Connecting Devices to a VAC/16 Junction Box

Each full-duplex line on a VAC/16 junction box can support an RS–232–C
asynchronous terminal, modem, serial printer, or other device. Figure 4–5 shows
the location of the device connectors on a VAC/16 J-box assembly.

Recording Device Line Information
If your system uses the DG/UX operating system, fill out the worksheet in
Figure 4–6 as you connect external devices to your VAC/16 J-boxes. (Use the sample
in Figure 4–7 as a reference.) You will need the information recorded on the
worksheet later, when your operating system documentation directs you to set
device characteristics such as baud rate and parity. Leave the "tty Line" column on
your device worksheet blank. Appendix B contains extra worksheets that you can
copy.
If your system will run DG/UX Release 4.30 or one of its updates, see Installing and
Setting Up the DG/UX System on Stand-Alone Multiuser AViiON Computers for
information on determining tty lines and specifying device characteristics. If your
system will run DG/UX Release 5.40 or higher, see Customizing the DG/UX
System for this information.
