This chapter gives instructions for selecting a preset from the front panel of the
RCS-2700. For instructions on selecting or editing a preset with the RCU-67
Remote Control Unit, see the RCU-67 Remote Control Unit Instruction Manual.
For instructions on selecting, editing, or creating a preset with a Windows-based
PC, see the RCS-WIN Software Instruction Manual. For instructions on selecting
a preset with a contact closure, see “Wiring the Preset-Select Contact Closure” in
the Installation Chapter of this manual.
Selecting Presets from the Front Panel of the RCS-2700
You can select which of the 14 presets will go into operation at any given time
with the Preset button on the front panel of the RCS-2700.
To select a preset from the front panel of the RCS-2700 unit:
1. Repeatedly press the Preset button to progress through the available preset
numbers until you reach the desired preset number.
The display will progress from one preset to the next, starting at 1 and ending
at 14. When it reaches preset 14, it will start again at preset 1.
2. When the desired preset number appears on the display, hold the Preset
button down until the display goes blank, then release the button.
Releasing the Preset button before the display goes blank will cancel the
change. This feature prevents accidental changes.
The RCS-2700 main and expansion units will then change to the newly selected
preset. When this change is complete, the main unit will display the new preset
number in the “Preset/Code” window.
The change to the preset will take about two seconds for each main or expansion
unit in the system. For example, changing a preset in a system with a main unit
and two expansion units will take about six seconds.
Note: When you change a preset, the RCS-2700 will switch destination and
source assignments within the unit, causing a clicking sound. This is normal.
CODE AND LOCK/UNLOCK BUTTONS (7 & 8)
You can lock the Preset button on the RCS-2700’s front panel to prevent
accidental or unauthorized changes to the selected preset from the front panel.
When you first receive your RCS-2700 unit, it is set to the factory default code of
“0.” When the code is set to “0” the RCS-2700’s Preset button cannot be locked.
If you do not want to use the lock feature, you can leave the RCS-2700 set to the
factory default code of “0.”
If you want to lock the RCS-2700’s Preset button, you must first change the code
from the “no-lock” code of “0” to another single-digit code called an “unlock”
code, and then lock the unit. See the following section “Changing the Unlock
Code” for instructions.
Changing the Unlock Code
The process of changing the unlock code is the same whether you are changing
from the factory default code of “0” to an unlock code, or changing from one
unlock code to another.
• The RCU-67 Remote
Control Unit connects to
the RCS-2700 main unit
through up to 300 feet
(91 meters) of cable.
Category-5 cable is
recommended.
