Connecting Peripherals to a DHW42-CB Option
If the system has the DHW42-CB asynchronous communications option installed, the
system has two four-line asynchronous ports with modem control. You can connect up to
four peripherals to each of these ports using the breakout cable (BC29J-06) supplied with
the option.
To connect a peripheral to an asynchronous port, refer to Figure 2-17 and follow these
steps:
1. Set the ON/OFF switch on the peripheral to the OFF (O) position.
2. Make sure that the 120 pin to 2 x 50 pin cable supplied with the DHW42-CB is
installed. (Figure 2-17, Item 1)
3. Hold in the connector clips on either side of the 50-pin connector of the breakout
cable and connect it to one of the asynchronous cable ports on the back of the system
unit. (Figure 2-17, Item 2)
4. Release the clips. The hooks on the port secure the connector in place.
5. Connect one of the four EIA-232 connectors on the breakout cable to the peripheral.
6. Set the ON/OFF switch on the peripheral to the ON (l) position.
