4.2 Connecting through RS-485 Interface
Up to eight GV-R1352 readers can be connected together to the RS-485 interface on GV-
AS400 Controller. When multiple readers are connected to the same RS-485 interface, you
need to specify each reader an ID so that the controller can distinguish one reader from
another. You will need to:
1. Connect GV-R1352 readers to a computer to access the GV-RK1352 Config AP.
2. Define the ID number of each GV-R1352 reader on the GV-RK1352 Config AP.
3. Wire GV-R1352 readers to GV-AS Controller.
Note: If only one GV-R1352 reader is connected to GV-AS Controller through RS-485
interface, you can skip steps 1 and 2, and the default ID number for the reader will be 0.
4.2.1 Connecting GV-R1352 to a Computer to Access GV-RK1352 Config AP
Using the GV-RK1352 Config AP included in the software CD, you can define the ID
numbers of multiple readers connected through RS-485 interface.
To start the GV-RK1352 Config AP, you have to connect GV-R1352 to a computer through
GV-COM, GV-Hub or GV-NET/IO Card V3.1.
