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.
