1.5 Connect the Reader to GV-AS Controller
You can connect the readers to GV-AS Controller through Wiegand or RS-485 interfaces.
Note that the connection between the reader and GV-AS Controller varies with different
controller models. To see how many readers can be connected to a GV-AS Controller, refer
to
1.7 The Number of Readers Supported by Controllers
.
Note:
Each GV-QR1352 / DES1352 consumes 85mA of power. The total power
consumption of the output devices and readers connected to GV-AS Controller must be
under
3A
(for GV-AS210 / 2110 / 2120),
3.5A
(for GV-AS410 / 4110 / 4111),
5A
(for GV-
AS810 / 8110 / 8111),
3A
(for GV-AS1620). Connect an external power supply if the power
supplied from GV-AS Controller is insufficient.
1.5.1 Connect through Wiegand Interface
The following diagrams use GV-AS410 Controller as an example. Up to eight readers can be
connected to GV-AS410 through the controller’s Wiegand interfaces.
