a main unit and displays the preset number. If the address switch is set to 1, 2,
and so forth, then the unit functions as an expansion unit and displays the
expansion unit numbers “U1,” “U2,” and so forth on its front-panel display.
In a multi-unit setup, the main unit is the only unit that will display the
currently selected preset. All of the expansion units will display only their unit
number in the multi-unit setup.
For more information on selecting or changing an address with the address
switch, see the section entitled “Setting the Address Switch” in the Installation
Chapter.
CODE-RESET BUTTON (2)
If you forget or misplace your unlock code, there are only three ways to unlock
the RCS-2700 unit’s Preset button without it:
• Try all 32 unlock codes.
• Use the Code-Reset button to restore all source/destination assignments to
their factory default positions. This will also reset the unlock code back to the
“unlock” code of 0. For instructions, see the section entitled “Using the
Code-Reset Button” in the Installation Chapter.
• Use the Code-Reset button in conjunction with a PC and RCS-WIN software
to set the unlock code back to the “unlock” code of 0 without changing the
source/destination assignments back to their factory default settings. For
instructions see the RCS-WIN Instruction Manual.
REMOTE RCU-67 REAR-PANEL JACK (3)
An additional RCU-67 Remote Control Unit can be connected to the rear panel
of the RCS-2700 unit. It connects to the RCS-2700 with Category-5 cable
terminated with RJ-45 connectors.
Only one RCU-67 Remote Control Unit can operate at any one time.
Communication with an RCU-67 connected to the rear-panel will be suspended
if an RCU-67 is plugged into the front-panel jack. The front-panel RCU-67
always takes precedence over the rear-panel RCU-67.
Warning:Do not connect a PC to the PC serial port while an RCU-67 is plugged
into the rear-panel RCU-67 jack. Doing this will connect multiple
serial ports on the rear panel which are not designed to be connected.
Either one or both of the ports will not work.
PC SERIAL PORT (4)
For ultimate programming capability, you can connect a PC (Windows
95/98/ME/2000) to the PC serial port on the back of the RCS-2700 main unit.
You can then program the RCS-2700 directly from the PC. The PC must have
the RCS-WIN program installed.
Do not connect an RCU-67 Remote Control Unit while the PC is in use. If you
connect a front-panel RCU-67, communication to the PC will be suspended. If
• With the Code-Reset
button you can set the
RCS-2700 preset button
back to a “no-lock”
status.
Warning: Do not connect a
PC to the PC serial port
while an RCU-67 is
plugged into the jack on
the rear panel.
• The “preset-select”
contact closure allows you
to use an external device
such as a wall- or
panel-mounted button to
change presets.
