Figure 7: Expanding the system with an RS-485 signal distributor
1. Keypad (KTD-405 keypad shown)
2. I/O box
3. RS-485 distributor
4. See section “RS-485 ports” on page 9
Caution
:
Most signal distributors are unidirectional. This means that the signal
only flows from the input towards the outputs. Consequently it is not possible to
connect several keypads.
See section “RS-485 ports” below to configure the RS-485 port communication
settings.
