connectors

CH1 and CH2

Before installing a Piggyback in the plug-in location (see section Replacing

Piggybacks on page 23), the pin assignment of the D-SUB9 connector (CH1/CH3 and

CH2/CH4) has to be selected via DIP switches, which can be found inside the device

at the plug-in locations.

Figure 11: DIP switches (left: CH1/3, right: CH2/4).

The pin assignments of the D-SUB9 connectors depend on the used bus transceiver

configuration inside the VN1630. A list of available Piggybacks and their D-SUB9 pin

assignments is included in the separate accessories manual.
