Interfaces
A2.4 Control Interface
A2.4.1 LAN interface
Please see A2.1.3, Page 103.
A2.4.2 Keypad 1,2 interface
To this interface you can connect an external b-line XT Keypad to control the
system. If you want to connect two Keypads simultaneously, you need an
adapter cable. Alternatively, if you don’t want to use the LAN interface to
connect a PC to b-line XT, you can also use the RS232 interface. To connect a
PC you need a 1:1 connecting cable, in which Pin 2 and Pin 3 are not crossed.
Additionally, Pin 5 GND must be connected. The remaining Pins are not used.
A2.4.3 TTL/RELAY interface
Via this interface external control signals can be used.
