Mounting And Connecting The PRM
Now you can begin to connect your Student Camera System components to your CameraMan camera, and audio equipment.
Mounting the PRM
1. Mount or place the Programmable Response Module in the desired location, being sure to leave
sufficient space to allow access to the connections on the back panel.
A rackmount is also available.
2. Verify that the switch on the front of the PRM is turned OFF.
3. Mount or place the PRM power supply in a convenient location near the PRM.
4. Plug the connector from the power supply cord into the DC POWER jack in the back of the PRM.
5. Connect the other end of the power supply into a 100-240 VAC source.
The PRM Power Supply and CameraMan Power Supply should not be interchanged.
Connecting Microphones To The PRM
1. Place the microphones around the room, and label them accordingly
(i.e.: numbered 1, 2, 3, etc).
2. Connect the microphone via the appropriate length microphone extension cable (not
included) to the optional microphone “Y” Cable (5-pin mini XLR to 3-pin male
XLR/2-pin female Phoenix connector).
3. Connect 3-pin male XLR to your room’s microphone mixer/phantom power source.
4. Connect the 2-pin female Phoenix Connector (green connector block) to the appropriately labeled
PRM input (i.e.: 1, 2, 3, etc).
5. Repeat steps 2-4 for all remaining microphones.
If you are using non-ParkerVision supplied “Y” Cables, follow these instructions to connect the
2-pin female Phoenix Connector wires to the green connector block:
1. Strip a short section (approximately 0.15”) off the end of the wire.
2. Insert the wire into the screw terminal slot on the connector plug.
3. Tighten the terminal screw.
4. Repeat steps 1-3 for the other 4 wire-pairs in that connector block.
If you are using microphones which are polarity sensitive, the inputs should be wired as
follows:
1. The positive lead, from the contact closure of the microphone, should be wired to the top
input of the pair, labeled “+”.
2. The negative lead, from the contact closure of the microphone, should be wired to the lower
input of the pair, labeled “-”.
All of the inputs labeled “-” are wired together internally and connected to ground.
