Connecting to GV-AS Controllers
There are three ways to connect a camera reader to GV-AS Controllers:
Wiegand
,
RS-485
and
network
. Below we use GV-AS400 Controller as an
example.
7. Place camera reader on the mounting plate and thread the cables
through the rectangular hole.
8. Secure the security screw on the bottom.
1. Wire GV-CR420 to GV-AS Controller
a. Connect a wire to the Wiegand pins of the GV-CR420 and the
other end to the Wiegand pins on the controller.
b. Connect a wire to the GND pin of the camera reader in addition to
the existing black GND wire for power cable, and connect the
other end to the GND pin on the controller.
Wiegand
Note:
Each camera reader must be connected to a power adapter
instead of using the power from GV-AS Controller.
