2.5.8 Digital I/O, RS485, IBIS, GPS, BMK
The HDSub 44 (female) socket offers connectors of alarm notifiers, the RS485 serial interface and to
establish a connection to your IBIS bus (Integrated On-board Information System), BMK (Rail Media
Multilink system) or GPS receiver. Please note that only GPS receivers and navigation systems
distributed by DResearch are supported.
Connect the GPIO (30 pin) VZGPIO plug set to this socket. The connector offers up to 8 sensor
(optical coupler input) connections. Furthermore, 4 switch outputs are available (2 x relay, 1 x high-
side switch, 1 x optical coupler output). The optional GPIO (44 pin) VZGPIOALL plug set allows you to
use the IBIS and RS485 serial interfaces. Alternately, you can connect the GPIO tester (available on
request) to this socket.
