INSTALL PRINTER (IF AVAILABLE)
To connect printers such as DIGITAL's LA120 or LA34, you must use null modem cables which
terminate at both ends with RS232 female connectors.
Use the following procedure to attach a printer to the VT 180. DIGITAL recommends using a
BC26U-15 null modem cable. If you use another cable, make sure it has a right-angled female con·
nector (to attach to the VT180) and is wired as follows.

nector on the top left side of the module access cover. See Figure 2-23.
2. Attach the other end of this cable to the printer.
