CAN-GC5 has exactly the same function as CAN-CAB1 as available from MERG.
This unit is a handheld like CAN-CAB1 but slightly larger.
It could also be used as a stationary unit, mounted in a switchboard.
It contains no difficult SMD parts, so it is easy to assemble.
With a few small alterations, it is mainly a copy of the unit as published in MERG Journal of dec 2017.
The previous MERG CAB1 is a very nice handheld unit, but unfortunately for most people very hard to build your own, and no longer available from MERG.
Because of the nice handheld size, it was hardly possible to build CANCAB without the use of SMD parts.
This version is slightly larger, but still good to use for 1-hand control.
On the other hand, when you like to build several of these control units in a switchboard, there is no need to make it that small.
That is way this unit comes in.
All parts have standard size, no SMD parts are used.
Display and potmeter are all on-board. The firmware is a bit different from CANCAB1, because of universal output for various types of displays.
There is a limit of 32 controllers to be used in the same system.
The board is connected to CBUS J3 on CAN-GC3.
The complete ordered kit comes with front plate and box with pre-drilled holes in front cover.
The kit has two connectors for CBUS, one on top-side and 1 on bottom side.
It is your choice where to connect the cable.
Both connectors cannot be used at same time, like for connection to the next CAN-GC5.
There is not yet an English manual for this board, but the operating instructions according use of keyboard are
mainly the same as
If after selecting a loco address the following message is shown on the display:
The selected loco is probably in use by Rocrail.
Select Release throttle to make it available for the CAN-GC5.

|The complete list of materials for OLED use|
|N.B. Only complete ordered kits will be supported!|
Generally we have two different 8 x 2 displays, both useable:
LCD, with background illumination, here you will need a type without contrast adjusting option (pin 3 not connected)
OLED, which only needs pin 1 to 14.
Displays with 14 pins (like OLED types), or 16 pins (like LCD with backlit panel) are possible.
Be sure NOT to mount R5 with use of OLED.!
Any questions ? ask Peter
2) First mount all:
5) Fixing the front plate.
5) Fixing the pcb support.
It is preferrable to support the keyboard with an extra point in the middle.
For that, a pcb support M3 x 10 is added.
Put the M3 washer on it and screw a m3 nut to position it to the end.
Insert the support on the bottom side between S1 and S2 and fix it with the 2nd nut.
6) Fixing the leds and finish.
