Section 8. Internal Jumpers
There are two sets of jumpers that are internal to the camera. One set of
jumpers is used to select either RS-232 or RS-485 communications on the
Power I/O cable. The other jumper set is used to select a pull up or a pull
down resistor on the External Trigger input line.
Refer to Section 20 Backplate Removal Procedures for details to remove the
backplate to access the internal jumpers of the camera.
8.1 RS-232 / RS-485 Jumpers
The jumper locations are shown in FIGURE 8-1. There are three jumpers that
can be moved from either the left or the right 2x3 jumper posts. When the
jumpers are on the right 2x3 jumper posts then the RS-232 output is selected
(Factory Default position). To change the serial output format from RS-232 to
RS-485 move all three jumpers from the right to the 2x3 jumper posts located
in the left position. Always move all three jumpers and never install additional
jumpers.
The available communication interfaces can be configured with the cameras
web interface or via the Device Configuration Utility. The RS-232 and RS-485
interfaces can be configured to a range of baud rates between 9600 and 115200
bps. Both interfaces support only the PakBus protocol.
