CGU 04i DESCRIPTION
22
Circuit example:
The CIO 2 modules are connected by the help of KD-51 cable (cable 1:1).
The connector K1 is input, K2 output to other CIO 2 module. By serial modems connection
the addresses are automatically assigned. In the direction from modem the addresses raises
uplink: 1,2,3,4 and 5. Maximal module number in series is five. See reference
