1.3 QUICK SETUP
The following instructions are a quick start for setting up the 1788-R with a single Model 1788 or a
bank of Model 1788s. The Model 1788s should already be installed. If they are not installed, refer to the
Model 1788 User’s Guide.
To interface the 1788-R, it must first be connected to the power supply via a DB-25 connection. Use
either the supplied parallel cable or any standard parallel DB-25 cable. The maximum cable run for
guaranteed operation is ten feet.
Using either the RS-232 or RS-422 DB-9 connectors on the 1788-R Power Supply (labeled “To Preamp”)
to connect the 1788-R to the Link In (RS-232/RS-422) on the first Model 1788 in the system using the
appropriate connection cable. Use a null modem cable when connecting via RS-232 and a standard
serial mouse/monitor extension cable when connecting via RS-422.
Note: On older Model 1788’s the DB-9 connectors are labeled Master RS-232 and RS-422.
For long communication distance (> 100 feet, 33 meters) always use the RS-422 communication link.
For shorter distances choose between RS-232 and RS-422 based on availability of the proper communi-
cation cable.
Place the 1788-R Power Supply either on the floor close by the remote or if the remote is mounted in a
rack the power supply can be physically attached to the back of the remote. Four screws are supplied
for that purpose.

Refer to sections 3.0 for more details on interfacing the 1788-R into a system, particularly
a system running the proprietary, PC-based, 1788 Remote Program.
