Figure 3-2. RS485 “Star” Connection
When V1691 is used in a “Daisy Chain” configuration, remove the
120-ohm terminating resistor from all but the last Receiver (see
Figure 3-3, 3-4). Remove Manchester Jumper J200, and RS485
Jumper J201 on the PCB to eliminate the terminal resistor.
The green LED labeled “CODE” on V1691 receiver/driver
illuminates when the unit is receiving valid control code. The LED
turns off immediately after the control code disappears.

3.1.2 Pan/Tilt and Lens Connections
The connection to a Pan/Tilt unit and a motorized camera lens is
with a 12-pin connector. This connector, labeled J300, J301 is
located on the main PCB (see Appendix II). A mating 12-position
screw-terminal connector plug is provided.
When wiring the connector, insert each wire carefully with
approximately 0.25 inch of insulation removed. Screw down the
clamping screw on each pin of the connector.
Pan/Tilt Wiring:
1.
Check the power supply cable to make sure the power is off.
2.
Locate the Pan/Tilt and Lens connector on the side of the
receiver/driver near the power cord.
3.
Insert the Pan Right wire of the Pan/Tilt unit into the pin location
for Pan Right.
4.
Insert the Pan Left wire of the Pan/Tilt unit into the pin location
for Pan Left.
5.
Insert the Tilt Up wire of the Pan/Tilt unit into the pin location
for Tilt Up.
6.
Insert the Tilt Down wire of the Pan/Tilt unit into the pin location
for Tilt Down.
7.
Insert the Pan/Tilt Common of the Pan/Tilt unit into the pin
location for Pan/Tilt Common.
Lens Wiring:
1.
Check the power supply cable to make sure the power is off.
2.
Locate the Pan/Tilt and Lens connector on the side of the
receiver/driver near the power cord.
3.
Insert the Iris wire of the Lens unit into the pin location for Iris.
4.
Insert the Focus wire of the Lens unit into the pin location for
Focus.
5.
Insert the Zoom wire of the Lens unit into the pin location for
Zoom.
6.
Insert the Lens Common wire of the Lens unit into the pin
location for Lens Common.
Note:
Do Not Connect the Lens Common to the Pan/Tilt Common.
3.1.3 Camera Power Connections
V1691 receiver/driver provides 24VAC and 14VDC power source
for camera (See Appendix II). Please refer to section 3.2.3 for
details.
3.2. Setup
3.2.1 DIP Switch SW200
DIP Switch SW200 is used to set the local camera ID, ranging from
1 to 255. Besides, it could be used for system testing. For details,
please refer to the appendix
Ⅰ
.
Note:
After the address is changed, it must be re-powered to control
the receiver.
