INPUT AND ENCLOSURE POWER  
The receiver is configured for 120 VAC operation. The input power and enclosure power are  
connected to a terminal strip located underneath the PC board.  
To change the receiver input power to 230 VAC and/or to connect power to the enclosure, do  
the following. Refer to Figure 1.  
1.  
2.  
3.  
Loosen the thumbscrews on the PC board (refer to Figure 1) and move the board out of  
the way.  
Remove the protective shield positioned over the terminal strip by loosening the thumb-  
screw that holds it in place.  
230 VAC Only - Remove the factory-installed 120 VAC power cable. Insert the 230  
VAC power cable through the feedthrough gland at the base of the receiver. Connect to  
terminal strip.

5.  
Insert the enclosure cable through the feedthrough gland at the base of the receiver.  
Connect to terminal strip. Enclosure voltage is always the same voltage as the input volt-  
age to the receiver.  
Replace the protective shield over the terminal strip and reinstall the PC board.  
ERD97P-AUX, OPTION BOARD (ALARMS AND AUXILIARIES)  
To install the ERD97P-AUX board, do the following. If the ERD97P-AUX is already installed,  
proceed to step 4.  
1. Locate P7, the 16-pin female connector located on the main board of the receiver. Re-  
fer to Figure 1.  
2. Insert the male connector, located on the bottom of the ERD97P-AUX board, into P7.  
3. Secure the ERD97P-AUX board to the main PC board with three Phillips head screws  
and lock washers. (The three screws and lock washers were packaged with the  
ERD97P21-U Receiver.)  
4. (Optional) The auxiliary switches are factory set for remote (keyboard) operation.  
The option board’s auxiliary functions can be controlled manually by resetting the  
Manual Auxiliary Control switches to the ON position. Refer to Figure 2.  
5. (Optional) The auxiliary output relays are factory set in the normally open (NO) position.  
To reset the auxiliary output relays to normally closed mode, change the jumpers to  
the NC position. Refer to Figure 2.  
EQUIPMENT CONNECTIONS  
All connections to the PC board and option board are made through easy-to-use terminal  
strips. To make equipment connections, thread cable/wire through the feedthrough glands  
located on the base of the receiver. Refer to the Wiring Table (located on the inside lid of the  
receiver) and the printed labeling on the circuit boards. Use a small, slotted screwdriver to  
connect wires to the terminal strip.  
WIRING TIPS  
Pan/Tilt –The ERD9721-U has two connections for wiring pan/tilt preset operation.  
a. SL/PP Models – Wire Pan A to the pan/tilt connection that is labeled “SL (360°)  
Preset.” Wire Pan B to the pan/tilt connection that is labeled “Pan Preset.”  
b.  
PP Models – Pan A is not used. Wire Pan B to the pan/tilt connection that is labeled  
“Pan Preset.”  
Alarm Inputs – The main PC board has one alarm input, which is normally open. The  
ERD970-AUX option board provides an additional eight alarm inputs (normally open), as  
well as eight auxiliary outputs.

JUMPER SETTINGS  
1. RX Termination – To daisy chain receivers (connect two or more receivers together),  
reset the RX Termination jumper to the non-terminating position. The last receiver in  
the daisy chain is the terminating unit, do not reset the jumper.  
2. TX Termination – Not applicable.  
3. Alarm Out – The ERD9721-U alarm output can be set for normally open or normally  
closed operation.  
VOLTAGE AND FUSING OPTIONS  
The ERD97P21-U Receiver can be configured to operate at 24 VAC, 120 VAC, or 230 VAC.  
Seven plug-in connectors and nine fuses are included with the ERD97P21-U Receiver.  
Install the proper voltage cubes and fuses. Refer to Table A and Figure 1.

*The receiver comes with three enclosure fuses (1.5A, 3A and 5A). Select the appropriate  
value for your application using the following steps:  
1. Determine the full-load wattage requirements of the enclosure.  
2. Divide the enclosure wattage determined in step 1 by the input voltage to the receiver.  
3. Select a fuse value that is close to, but not less than, the value determined in step 2.  
Example:  
An environmental enclosure with 120 VAC input, heater, defroster and window wiper.  
From the enclosure specifications:  
Heater ................... 160 watts  
Defroster ............... 15 watts  
Window Wiper ....... 90 watts  
Total wattage ......... 265 watts  
265/120 VAC = 2.208 Amps  
Therefore, a 3A fuse will work for this sample enclosure.

OPERATION  
The ERD97P21-U Receiver runs a configuration cycle at startup to detect preset capabili-  
ties and verify that the unit functions properly.  
To start the receiver, plug it in. Set the ON/OFF switch to ON. The pan/tilt unit tilts down and  
pans left, followed by a tilt up and a pan to the right. The lens zooms out and focuses far.  
The lens zooms in and focuses near. During the configuration cycle, the receiver will not ac-  
cept any commands.  
LENS VOLTAGE ADJUSTMENT  
The lens voltage is adjusted manually by turning a potentiometer on the PC board. Refer to  
Figure 1. The range of adjustment is from 5 VDC to 10 VDC.  
MOTION COMMANDS  
Motion commands tell the receiver to start or stop a pan/tilt or lens motion. More than one  
motion command can be requested at a time. There is a 60-second timeout on all motion  
commands. If the receiver initiates a motion and no commands are received for 60 seconds,  
the receiver stops all motion. This prevents the receiver from being driven continuously if  
communication problems arise.  
PRESETS  
The ERD97P21-U can store up to 80 presets. (To set presets, refer to the instruction  
manual for the control unit.) All presets are cleared if the preset clear switch is pressed and  
held down while the processor is either reset or powered up.  
If any motion command or alarm is received during a move to a preset position, the com-  
mand is aborted and the new command is initiated.  
ALARM AND AUXILIARY FUNCTIONS  
The alarm inputs are reserved for the first nine presets. If an alarm becomes active and  
there is a preset for the alarm, the preset is initiated. For example, if alarm 4 is activated,  
the camera moves to preset 4. If more than one alarm is activated, the receiver sequences  
between the corresponding presets, stopping for five seconds at each preset.  
If a motion command or move to preset command is received while alarms are active,  
alarm processing stops and the command is processed. After 60 seconds, alarm process-  
ing resumes. The alarm lockout timer is reset if all alarms become inactive. Alarm process-  
ing restarts immediately if an alarm is triggered.  
AUXILIARY OUTPUTS  
There are eight auxiliary outputs on the optional alarm/auxiliary board. These relays are  
opened and closed by receiver software commands.  
SCANNING  
FRAME SCANNING  
To start frame scanning, call preset 98.  
To stop frame scanning, call preset 96.  
Panning motion is not continuous during frame scanning operation. The receiver moves the  
pan/tilt unit to the right for three seconds, stops for three seconds, pans to the right again  
for three seconds. When the unit hits a limit stop, it reverses direction.  
If any motion command or alarm is requested during frame scan, the scanning is aborted  
and the new command is initiated.  
8
Pelco Manual C939M-D (7/00)  
 
RANDOM SCAN  
To start random scanning, call preset 97.  
To stop random scanning, call preset 96.  
When random scanning starts, the pan/tilt unit moves to the left for 60 seconds or until it  
hits a limit stop. When a limit stop is hit, the unit pans to the right for 60 seconds or until it  
hits a limit stop. The receiver then starts a random cycle of movement, panning and stop-  
ping for a random amount of time.  
If there are no limit stops, the movement time varies between 1 and 60 seconds. If there are  
limit stops, the movement time varies between 1 second and the time it takes to move be-  
tween the limit stops. The time between movement varies from 4 to 60 seconds. If any mo-  
tion command or alarm is received during random scan, the scan is aborted.  
TROUBLESHOOTING  
RESET  
If the receiver settings are changed (for example, DIP switch or voltage settings) or if the  
unit locks up, press the reset button located on the main PC board. Refer to Figure 1.  
The reset command starts the receiver’s configuration cycle. The pan/tilt unit tilts down and  
pans left, followed by a tilt up and a pan to the right. The lens zooms out and focuses far.  
The lens zooms in and focuses near. The receiver will not accept any commands during the  
configuration cycle.
