Connecting Synchronous Devices To A Vsc/3 Controller; Cables For Synchronous Devices And The Vsc/3 Board - Data General AViiON Series Customer Documentation

Connecting Synchronous Devices to a VSC/3
A single VSC/3 controller in your system can support three lines, with ports on the
air dam at the rear of the VSC/3 board. Each full-duplex line can support an
RS–232–C synchronous modem or other device. Figure 4–25 shows the location of
the device connectors on a VSC/3 board.

NOTE: You specify the characteristics of synchronous devices through your
communications software. You should refer to the device-specific
documentation and your X.25, SNA, PAD, or other synchronous
communications documentation for information on setting characteristics,
such as baud rate, to conform to your system requirements.
Synchronous devices connect to the VSC/3 board in your computer through cables
with male DB25 connectors. To connect synchronous devices to the VSC/3 board,
use one of the cables listed in Table 4–6.

NOTE: Make certain you use the correct cables to connect your synchronous
devices. Although the RS–232–C interface supports many devices, your
device requires the correct cable in order to work properly.
