9.1.4.C Connecting GV-Readers and GV-GF Fingerprint Readers
You can connect up to 4 units of GV-Readers and GV-GF Fingerprint Readers to GV-
ASBox. Multiple GV-Readers and GV-GF Fingerprint Readers can be connected with a
single RS-485 cable to separate RS-485 interfaces on GV-ASBox.
Since Wiegand communication distance is shorter than RS-485’s, you can choose GV-
Reader and GV-GF Fingerprint Reader supporting RS-485 communication to add another
door control and meet the need of long-distance installation.
Use the RS-485 B+ B- to connect to GV-Readers and use the RS-485 interface to connect
GV-GF Fingerprint Readers. Refer to the figure below to see where the RS-485 interfaces
are located. When multiple readers are connected together, an extra power supply to each
unit is required. Use the auxiliary power output of 12V and GND on GV-ASBox to power on
each unit.
Figure 9-3
To define each GV-Reader and GV-GF Fingerprint Reader, you need to use the GV-
AS100/GV-AS110/GV-AS120 Web interface. See 9.3.2.G Extended Reader Setting.
Note: The RS-485 connector on GV-ASBox is only designed for the connection of GV-
Readers and GV-GF Fingerprint Readers.
