3.4.4RS232C/V.35 Shunt

You can connect an external composite link device using either an RS232/V.24 or a V.35 interface to the DataTalker’s External Composite connector. To configure the DataTalker for V.35 operation you must move a shunt on the main circuit board. Two shunt sockets are located on the back left side of the board (Figures 3-3 and 3-4). When an external composite link device with an RS232C/V.24 interface is connected to the composite link, the shunt is installed in the RS232 socket (factory default). When the external composite link device has a V.35 interface, you must move the shunt from the default RS232 socket to the V.35 socket. The V.35 indicator on the front panel lights when the shunt is in the V.35 position.
