Testing Mode
Control V1691 receiver without the cable connection.
Follow the steps above to use DIP Switch SW200 to set the testing
mode. For details on the switch position on the PCB, please refer to
the appendix

.
3.2.3 Lens Voltage Adjustment
V1691 is adjustable for a range of camera Lens servo voltages. The
lens output voltage can be adjusted through the selection switch
(R114) on V1691 PCB. The voltage range is from 6V to 14V, and
the default voltage is 10V.
3.2.4 Jumper Setting
Note:
The PCB edge is in the left of the jumper switch.
Terminator Setting
Terminator jumper: Manchester ---J200; RS485----J203

Communication Mode Setting
V1691 receiver/driver could select Manchester or RS485 through
the internal jumpers J204 and J201 on the PCB. The jumper is set as

AUX Mode Setting:
The AUX2 can set the “Auto pan” through jumper J309 .The
jumper is set as below:
J309
A 24VAC output always exists between AUX2A and VACCOM.
There is 24VAC output between AUX2B and VACCOM when the
receiver/driver receives AUX2 ON command; and the 24VAC
output between AUX2B and VACCOM will disappear when the
receiver/driver receives AUX2 OFF command.
In the case that the AUX2 is set to “AUTO PAN”, the pan/tilt
device will start AUTOPAN action when the receiver/driver
receives AUX2 ON command; and the pan/tilt device will stop
AUTOPAN action when the receiver/driver receives AUX2 OFF
command.
Note:
The factory default mode is AUTO PAN mode.
