CAN-digital-Bahn
The SwitchMann-GBS replaces all variants of the old SwitchMann modules. It also changes slightly the concept and, as the name has always said, it is now only intended for switching magnetic addresses or also for triggering routes via a start-finish button of the RoutenMann-GBS .
If possible, only pushbuttons (NO contacts) should be used. Toggle switches can only be used in operating mode T2, i. e. the two-button operating mode.
When switching routes, it is particularly important that only buttons (NO contacts) are used, because the RoutenMann-GBS also pays attention to the sequence in which the buttons are pressed and whether they have been released again. This information then triggers the desired route.
The position of the magnetic address is now displayed separately via another module, the SwitchMonitor-GBS , which allows you to compose your track layout control panel even more individually.

Funktional Mode:
The properties of the SwitchMann-GBS can be set via the last three DIP switches with the numbers 6, 7 and 8.
No further programming of properties is currently required. The addresses to be switched are set in fixed blocks according to the selected operating mode via the first five switches of the DIP Switch. The tables can be found below under the heading "Adressen & Codierung".
Switch 8:
With switch 8 you can choose between the request of DCC or Motorola switching commands. To change the data format, the module must be disconnected from the operating voltage once and switched on again after the switch has been changed.
If the switch is "OFF", switching commands for Motorola data are sent. If the switch is "ON", the same addresses are addressed via the DCC format.
In pure CAN systems, this selection plays only a subordinate role, since there are no track formats in CAN. Here only absolute addresses are used and the track format is part of the address, so you have twice as many switching addresses available.
Switch 7 is used to select between the two operating modes "T1/Start-Finish" or "T2". It is not possible to change the operating mode during operation. To change the operating mode, the module must be disconnected from the operating voltage once and switched on again after the switch has been changed, this needs to be done also when selecting the data format.
T2 mode: Switch 7 "ON"
In T2 operation, one solenoid address is operated via two keys, therefore the designation T2.
In this operating mode there is a separate button for each switching direction of the magnet address. If the key is pressed, the SwitchMann-GBS sends the corresponding address with the direction for which the key was pressed. The data format selected via switch 8 is used.
When generating the switching commands, no attention is paid to the current position of the address, because the direction sent always corresponds to the key pressed.
In operating mode T2, up to eight magnetic addresses can be operated with a SwitchMann GBS. This operation is very well suited for the construction of simple control panels.
T1/Start-Finish: Switch 7 "OFF"
The T1 mode with only one button - therefore T1 - is intended to get by on a control table with fewer buttons. An address is always toggled with the same key.
In start-finish mode, the SwitchMann GBS works as in T1 mode, only when extended by a RoutenMann-GBS does it become a "start/finish" mode.
In T1 mode, the opposite direction of the last key actuation is always switched with the data format selected via switch 8. The turnout or the signal switches back and forth by pressing the key twice. In T1 mode, up to 16 magnetic addresses can be operated with one SwitchMann. The SwitchMann-GBS also monitors the system bus for switching commands which are executed to these addresses by other sources and can thus automatically adapt the last switching position to the events from the bus. In addition, the switch positions are stored in the memory so that they are available the next time the game starts and the keys are preloaded according to the position before the last switch-off. This means that the turnout is always switched correctly the first time the button is pressed. (Saving and monitoring the system bus is only possible with new firmware from September 2018 on.)
Selection of the T1 operating mode is required for setting routes via start-finish buttons together with the RoutenMann-GBS . However, the direction and the selected data format play no role in the generated telegrams for switching the routes, because this is not taken into account by the RoutenMann-GBS . It only pays attention to the sequence and how keys are pressed. It can see from the data which key was pressed first as "Start" and remains pressed until a second "destination key" is pressed. More about this on the page of the RoutenMann-GBS.
(New function from September 2018 on:)
Switch 6 is the selection of the system on which the SwitchMann is to be operated.
If switch 6 is "OFF", the CAN bus of the SwitchMann automatically adapts to the data operation of the Märklin CAN.
If switch 6 is "ON", the CAN bus of the SwitchMann automatically adapts to the data operation of the ZCAN for operation with the Z21 or the Zimo world.
There is only one SwitchMann-GBS, the operating mode of the module is defined by this switch 6. An automatic detection would in principle be possible in most structures, but there may be system constellations where this would simply not be possible, therefore this setting must be made once by hand.

Adresses & Coding:
The address is set via the first six DIP switches. The number of possible addresses per module results from the operating mode selected with switch 7.
If one and the same address is to be operated from two positions, two SwitchMann-GBS can be set to the same address in different control panels without any problem; the "T1 or T2" operating mode is irrelevant.

The highest address that can be selected in T2 mode is 248, whereas in T1 mode it is 496.
If only CAN modules are used in its structure, the data format becomes a component of the address and it only plays a subordinate role. The limit of possible addresses in T2 mode is 496, because the CAN switch modules (WeichenChef etc.) can also process addresses above 320 of the motorola format. However, the assignment of the MM addresses over 320 can only be made via the learn button on the respective switching module. Or for the completely new modules, which are also suitable for both worlds, this can also be entered as CAN address via the service tool.
LED:
Since it is difficult to see whether such a rather compact module actually works, i. e. whether the keys are recognized and the corresponding telegrams are sent, there is an LED on the board.
The LED changes state after each switching command sent. This means: After switching on, the LED is initially on. If a key is pressed and the module is able to send this information via the CAN, the LED goes off. If you release the key after a while, an attempt is made to send this information via the system bus as well. Once this has been done successfully again, the LED lights up again and remains on again. This makes it very easy to see whether the system bus is active and the keystrokes can reach other users.
Error message:
If the LED flashes quickly, this indicates that the operating voltage of the module is too low and has dropped below 9 volts. The module flashes as long as the voltage is too low and does not send any switching commands. If the voltage rises again, the module continues to operate normally. The error does not have to be reset.
The connection of the buttons or switches to the SwitchMann GBS does not depend on the "Start-Finish" or "T2" operating mode and is also very simple, since no further external components such as "pull-up resistors" or similar are required. The switches only have to be NO contacts and these must be connected to the ground of the module. Please pay attention to the power supply here, the modules are not! galvanically isolated and should only ever be supplied from their own source within a track layout control panel, and should not have an electrical connection to the rest of the system. In this way, unnecessary problems can be avoided at the same time
.
The middle screw terminal on the board serves as the ground connection .
The power supply of all GBS modules must always be 12 Volt DC and should be provided by a PowerBox-GBS or the RoutenMann-GBS , so that several SwitchMann-GBS and other modules can be supplied if necessary.
