2.3 Connecting the Reader to GV-AS Controller
You can connect the readers to GV-AS Controllers through Wiegand or RS-485 interface.
Note that the connection between the reader and GV-AS Controller varies among controller
models. For the number of readers supported by a variety of GeoVision controllers, see the
compatibility table
.
Note:
1. GV-RK1352 / R1352 / DFR1352 is compatible with GV-AS100 / 1010 / 110 / 120 / 210
/ 2110 / 2120 / 410 / 4110 / 810 / 8110, GV-AS1620, GV-CS1320. However, to enable
the keypad function on GV-RK1352, you can only connect GV-RK1352 to the
controllers through the following interfaces.
 GV-AS100 / 110 / 120: Wiegand
 GV-AS1010: RS-485
 GV-AS210 / 2110 / 2120 / 410 / 4110 / 810 / 8110: Wiegand and RS-485
 GV-AS1620: Wiegand and RS-485
 GV-CS1320: RS-485
2. Each GV-RK1352 / R1352 / DFR1352 consumes 60 mA of power. The total power
consumption of the output devices and readers connected to GV-AS Controller must
be under 2.5A (for GV-CS1320), 3A (for GV-AS1620, GV-AS210 / 2110 / 2120), 3.5A
(for GV-AS410 / 4110) or 5A (for GV-AS810 / 8110). Connect an external power
supply if the power supplied from GV-AS Controller is insufficient.
2.3.1 Connecting through Wiegand Interface
The following diagrams use GV-RK1352 and GV-AS810 Controller as an example. Up to
eight readers can be connected to GV-AS810 Controller through the controller’s Wiegand
interface.
