CAN-GCA module firmware is based on CAN using the industrial CAN Bus.
|On all CAN-GC boards this termination resistor is already mounted and can be activated by setting a jumper.|
The best suitable cable for connection between all CAN-GCx modules is CAT-5 cable, mostly known as CAT-5 Patchkabel cable.
Almost any computershop or DIY Market sells this cable for pretty low prices. (e.g. Reichelt 4X2 AWG26/7-10)
| DB9 |
|3||+12V or LN||green||LN, LocoNet, for mixed systems|
Pin 2 and 4 are only needed when ORD-3 booster is used in the same system.
Changing wire colours could cause errors.
|For testing and small layouts.|
Standard full wired male to female extension RS232 cables are allowed, but up to a certain limit. (e.g.: Reichelt AK2300)
It is never experienced how many can be used. A few will not disturb the communication, but it is not able to conduct the full 3 Amp of the CAN-GC1(e).
