CAN-digital-Bahn
This module provides a possibility for feedback (four inputs) and also for switching up to two turnouts (or four lamps) via solenoid addresses. This makes it possible, for example, to equip remote corners of a system or modular systems more economically, since only one instead of two modules are required. It is effectively a half GleisReporter deLuxe and a half WeichenChef Magnet, which were combined on one board. For further information, the module descriptions of the GleisReporters deLuxe and also those of the WeichenChefs Magnet can be consulted. The ReporterChef also has a combination function that - if activated - connects the feedback inputs to the switching outputs so that function models (e. g. railway crossing) can be triggered directly. This will be presented in more detail later under the heading "Operation".
The ReporterChef can be operated by all devices of the CAN-digital-Bahn-Projekt, such as the CAN-StellPult (CAN control panel). Central Station 2 and Mobile Station 2 are also suitable for this purpose. In short, there are many ways to operate it.
The ReporterChef is connected via a normal network cable. It does not matter on which side a cable is plugged in, there is no front and rear.
In addition to the connection to the system cable, the ReporterChef also needs an operating voltage for the switching part, but no extra voltage is required for the feedback signals.
Of course, several ReporterChefs can also be integrated into a larger system structure; there is no address-related limitation. A ReporterChef can be programmed to addresses from the CdB, DCC or Motorola range.
Connection:
Turnouts, relays, LEDs with series resistor or incandescent lamps can be connected to each of the two output pairs of the ReporterChef. Each module has an external power supply and driver modules for current amplification.
The electrical design of the module is somewhat more complex than that of the other modules, as it combines all the positive characteristics of the two modules. The ReporterChef works with a total of three separate voltages:
Firstly, there is the supply voltage from the CAN bus (yellow part), which reaches the module via the StartPunkt 2. From this voltage it generates a second voltage (light blue part) via a galvanically isolated DC/DC converter, which is then used by the controller and the entire feedback section. So even the reporter part - as with the GleisReporter deLuxe - can only recognize its own tension.
Notice: A power supply unit that supplies 12V DC must be connected to StartPunkt 2. A supply voltage other than 12V DC will destroy the ReporterChef!
The entire power section for switching (green part) is another third unit that has no electrical connection to the controller. Here, too, the information is transmitted via galvanic isolation. This completely eliminates feedback effects to the track signal or the rest of the system via the bus during switching. Nevertheless, only one external power supply is required for complete operation.
The load per output may be up to 1.3A, but all outputs of the module together must not exceed a total of 5A!
The positive voltage, thus the PLUS connection for the consumers to be operated on this module, is located in the middle of each of the two 3-pole screw terminals.

The voltage at the outputs of the ReporterChef corresponds approximately to the applied operating voltage of the module. However, it is essential to note that an applied alternating voltage on the module increases by the value 1. 414 due to the rectification!
The track sections for the feedback that are to be reported as occupied can be connected as with the known s88 modules.
The counting mode of the inputs is from left 1 to right 4 .
Please note: every! ReporterChef must be connected to track ground via the first of the five screw terminals. Without this connection, the module cannot detect any vehicles on the tracks. A marking of the connections can be found under the screw terminals, which can also be easily removed for better installation of the cables. .
Addresses:
The 2 outputs of the ReporterChef are automatically set to addresses 1 and 2 in the Motorola address space.
With this module, the address can only be set using the Service Tool, which is described in more detail in the next section .

Combination mode (automatic function):
The module requires five instead of actually only two solenoid addresses for switching the outputs. The fifth address is used to switch the automatic function on or off. If the assigned address is red, the function is not active. If the address is set to green, feedback messages that are running in the bus system and the own inputs that can trigger a switching change at the four outputs on the module are also evaluated.
Two feedback addresses can be assigned to each output pair. Whenever they change from "free" to "occupied", the output switches once in the respective direction. The inputs can also be combined with feedback units from ReporterChef and/or GleisReporters deLuxe if the internal inputs have the same feedback address. For example, this way it is easy to extend the trigger distance for a railway crossing in a modular layout.
Another example is a simple train change in a small station.
In the figure on the right, two feedback addresses 1 and 2 are assigned to output 1. This means that if the automatic function is activated (address 5 green), output 1 always switches to red if an event occurs on track detector 1 from "free" to "occupied". If a train moves via contact 2, the ReporterChef switches the output to green.
So you can already realize a simple train change without a computer. The arriving train always switches the switch in the other direction behind it and starts the train in the track and vice versa.

If the outputs are used for switching solenoid drives with limit switches, the monitoring function can be activated via the service tool. The ReporterChef can, just like the WeichenChef Magnet, detect the positions of these drives and actively report them to the system bus. If you only switch lamps or something else than magnetic drives, you should not use this function, because the magnetic address in the control units would then only ever blink, as the Reporter would report a switching error.
The properties of the ReporterChef can be adapted to many operating requirements using the service tool. The following description is compatible with program version 001, which can be used with firmware 1. 3 or higher (from May 2016).

The program requires a CC-Schnitte, as well as Microsoft. NET. The tool is tested under XP and WIN 7 and does not handle errors as Windows would like it to. If an error occurs, the tool simply lubricates. This always happens if the values read out cannot be displayed by the tool. This problem can be quickly solved with the reset tool. To do this, simply call the module once and trigger a RESET, so all settings are reset and the tool should now be able to process the messages of the module. The RESET-Tool can also be found in the download area.
After starting the program, select the COM port of the CC-Schnitte. If you plug it into the computer after startup, you can add the new interface to the selection with "Reload".
This selection of the interface activates the "scan" button. If this is activated, all ReporterChefs are prompted to report to the PC. The selection window is filled with these messages. Each additional scan updates the selection, for example, if another ReporterChef is added or one is perhaps not displayed the first time.

The resulting list in the selection field contains all ReporterChefs, sorted by module ID. If a module with ID 0 responds, a message is displayed stating that an ID greater than 0 must still be assigned for this module. This assignment is made by entering a number in the module ID, which must be terminated with "übernehmen" ("transfer"). After this, a new scan of the bus system needs to be effected, since the module is now to report with its new ID. At present, up to 63 ReporterChefs can be managed in this way. If this is no longer sufficient, please report it, because this limitation is only due to the number of bits used.
If you now select a module from the list, it will be asked to transmit all its stored settings. In addition, "Position" shows the current position of the actuator and the current status of the inputs in the feedback area. However, the position display of the switching outputs reacts only to the absolute position messages of the ReporterChef. If no drive is connected to the output, the display remains grey.

Weichen (Turnouts):
On the left, the four addresses of the two outputs are listed; the corresponding data format DCC or MM is also displayed. The second address is only one option, so that both outputs (red/green) can be operated separately via two addresses. The option "second address" needs to be activated for this, otherwise the address entered here is of no significance.
With the different selection fields in the middle you can now set the output behavior of the ReporterChef:
"k84" means that the outputs remain switched on, whereby the outputs switch alternately depending on the required position. Before using this function, the module should be reset once so that all other internal settings are correct. Under certain circumstances, this function can be overwritten by settings around the fixed switching time .

If a check mark is set in "Stellungsüberwachung" ("Position monitoring"), an attempt is made to determine the position via the limit switches of the solenoid drives. If no unique end position is detected, an error message is sent and the corresponding displays in the control units blink.
"Spannung aus nach xxx ms" ("Voltage off after xxx ms") activates an individually adjustable time for each output, after which the drive is automatically switched off again by the module at the latest. If a time has been entered here, the shutdown also occurs if no shutdown command has been received via the CAN bus. The time entered must be calculated by 10, smaller steps make no sense here. If the ReporterChef receives an OFF command before the time has elapsed, the drive is switched off immediately. If you want to define a certain switching time for an output, you must do this via the "feste Schaltzeit" ("fixed switching time") and the "Impulszeit" ("pulse time").
.
Notice:
For example, if a solenoid address is constantly pressed on the CS2 on the keyboard, the switch-on command is constantly repeated, so that the set time is only processed after the last switch-on command received!
With the red and green buttons in the PC-Tool under "Test" you can switch the main address of the output to test it.
The slow switching of solenoid articles (slow motion) or blinking functions:
The function "feste Schaltzeit" ("fixed switching time") can be used to set a time that the output is switched on, independently of other settings. This is particularly important in conjunction with the PWM function. Here you set the period (= how often the tiny pulses are to be repeated) and the pulse time (= the time the output is switched on) for the slow switching of the solenoid drives. Since the movement usually takes a few seconds to complete, the fixed switching time must be used here, otherwise, for example, the output would switch off too early when the button is released in manual mode.

This function can also be used to generate blinking lights or to control the ringing mechanism of a railroad crossing without additional electronics.
Here are some rough values for the different functions:
With solenoid drives, however, you have to find out the optimum time for each drive by trial and error. There is no "standardised" setting here .

Magnetadressen (Setting addresses):
On the second page you can easily and conveniently set the solenoid addresses to which the respective output should listen. The virtual 5th address for the automatic function can also be programmed here. With this address the automatic function can be switched on and off. If the automatic system is not required, you should not use address 5 in the system or assign an address here that is not used, otherwise "ghost switching" may occur!
Set the second address of the outputs only if the corresponding function (second address) is activated, otherwise the addresses entered there will not be processed.
Automatikfunktion (Setting combined operation):
On the third page you can also set the feedback addresses to which the respective output should listen in automatic mode.
Rückmelder (Feedback):
This part corresponds approximately to the range of functions of the familiar service tool for GleisReporter deLuxe. Since the ReporterChef has no rotary coding switches, it is also used to assign the desired feedback addresses for the four inputs on the ReporterChef. These can be set to an address between 1 and 65000 without any restrictions - for example, they do not have to follow one another. Here is a possible limitation only with the used control software, which number this permits maximally. An example can be seen in the following figure of the tool:

Naturally there is a connection test, too. If the check mark is set in the field, an occupy message moves over the four detectors. This makes it easy to check whether the module's data arrives in the control software. This test remains switched on until the check mark is removed or the operating voltage on the bus system is switched off once. In this way, several modules can be switched to this mode one after the other and it is possible to check in the control program whether the messages are visible there.
Attention:
In this test mode, current messages are only partially displayed, the current input status is only transmitted again after the test has been completed.
Ein- und Ausschaltverzögerung (Switch-on and switch-off delay):
These fields are used to set the time that a message must be continuously present or deactivated at least at the input before it is to be transferred to the system. However, the settings can only be made here in a resolution of 10ms .
Gerätekennung (Device ID):
Here you can define virtual feedback systems within the one CAN bus or clearly distinguish the messages of the ReporterChefs in the bus system from other system users (CS2) by their identification.
In the control programs, you can set which device identifier is to be taken into account for the feedback. For example, you can avoid the problem when starting a program if the ReporterChefs send their messages to the PC via the CS2.
ReporterChefs respond to the request of the programs much faster than the Central Station can. The CS always reports what it found on the s88. If nothing is connected there, all messages that were received before are unfortunately overwritten again and it looks as if there are no vehicles on the system. If you now assign an device identifier here, the program can immediately discard the unnecessary messages from the control unit and there will be no incorrect start state.
.

If the messages are also required in the track layout of the central station, however, you can instruct the ReporterChef with the tick "sende auch Master CS2" ("send also Master CS2") to also send the feedback messages under the CS2 ID, so that it can display them.
The tool is free and can be downloaded from the download area of the homepage.
