Wiper is controlled via RS485 (Pelco D commands)
IR lamp switches an output contact, which can be used to force the camera to night mode.
Wiper
The RS485 connection of the HSG04 is fixed at:
Baud rateBaudrate: 2400
Data bits: 8
Parity: 1N
Stop bitbits: 1
The RS485 data settings on the camera must be the same
...
The RS485+ (brown) and the RS485- (Black) of the HSG04 must be connected to the camera D+ and D- of the camera.
...
Check the Quick Start Guide of your camera type for the correct pin location of D+ and D-, this may differ per model.
Example (BC920):
...
Note, : On the BC920, the Pin layout of the Digital connector is printed as I/0 1-7
...
IR synchronization
The IR lamp of the HSG04 turns on automatically in low light conditions.
I/O contact is available to force camera into night modes mode (black/white) to synchronize this process.
Good to know, the IR lamp is always “master” in this kind of installation and overruled overrules other IR related settings of camera.
Pin D01 DO1 and DI1 (White/Green is in this example) of HSG04 is the I/O contact of the IR lamp.
