3. INSTALLATION
3.1 Unpacking
The following is included with each SPLD multiplexer
•Multiplexer and external power supply
•Cable for connecting a modem or DSU/CSU
•Manual
•Information regarding warranty, maintenance contracts and
repair
3.2 Location
Place the multiplexer in a clear area where you can reach the front
panel for setup and the rear panel to connect the cables. The
multiplexer has an external power supply that requires a properly
grounded 120 VAC outlet. The total power cord length is about 12 feet.
3.3 Setup
Each SPLD multiplexer must have a unique DROP ADDRESS set into
switches behind the front panel. In addition, each data port must have
the proper speed, parity and flow control settings. This is also done
with switches. See Section 4 for the location and proper setting of
switches.
3.4 Connections
The SPLD is connected to the modem or DSU/CSU using the cable
supplied. Connect the Network port on the multiplexer to the RS-232
interface port on the modem or DSU/CSU. The modem or DSU/CSU
must be set for controlled carrier operation (RTS controlled from
interface). This is absolutely required for the system to operate
properly. See your modem or DSU/CSU manual for information on how
to set the unit this way. For information regarding data port
connections to DTE devices, see Section 6.
