1.3 SET-UP of the TCB4 Interface card
To ensure correct operation of the TCB4, the following settings are required:
1. DIP-switch S14 must be set, to configure the communication protocol and baud
rate used on Port 1 and Port 2 (see Chapter 3 ).
2. DIP-switch S9 must be set to configure the boards functionality (see Chapter 2.1 ).
3. Jumpers X13 and X14 must be set (see Chapter 2.2).
NOTE:
Once the TCB4 has been successfully installed in the CCU, replace the
top-cover and connect the mains supply to the CCU. Check the CCU for cor-
rect operation. If the CCU functions correctly, the CCU should be switched ON
for at least 24 hours to charge the back-up battery located on the TCB4.
