To other unit's control input
• Control Output Terminal Connections
Connect the control input terminals of all other
connected units using 2 control lines.
Caution
Be sure to connect only these
control lines to other unit's control
input terminals.
Connecting in parallel with control
lines from other equipment may
cause the unit to malfunction.

Note
To control a power distributor or PA
amplifier mounted in the same rack
as the unit using the unit's control
output terminals, provide an external
relay and power supply as shown
below to perform control with the
relay contacts.

[Control Input Specifications]
To other unit's
control output
• Connections to the Control Input Terminal
Connect the control output terminals of all other
connected units using 2 control lines.
• RS-232C Interface Connections
The NX-100 can be used to control such RS-232C
components as DTE and DCE components over a
network.
Use a "straight" cable fitted with a 9-pin D-sub
connector when connecting to DTE components
such as PCs.
Use a "cross" cable fitted with a 9-pin D-sub
connector for connecting to DCE components such
as modems.
NX-100 only
Tips
• Refer to p. 2-5, CONNECTIONS TO TERMINAL PLUGS, for control terminal connection procedures.
• When not using the RS-232C interface, place the supplied RS-232C cover over the terminal to protect it
against dust.
