Types of Door Access Control
GV-AS100 / GV-AS110 / GV-AS400 Controllers can be configured to support the following
types of door access control. By default, GV-AS 100 / GV-AS110 Controllers are set to one-
way control and GV-AS400 Controllers are set to two–way control.
• One-way control: A door is equipped with one card reader for entry. For example, a
user may swipe a card to open the door of office and push a button to leave from the
same door.
• Two-way control: A door is equipped with two card readers. The outer reader is
defined as entry reader and the inner reader is defined as exit reader. For example, a
user may swipe a card to gain access to a laboratory, and swipe a card to exit from the
same door.
• Mixed control: A mix of One-Way and Two-Way Control applications. Some doors are
equipped with one card reader for entry and some doors are equipped with two card
readers for entry and exit. For example, a building includes both office and laboratory
applications.
• One-way traffic: Two doors are applied for entry and exit separately. For example, in a
parking lot, a user may swipe a card at the entrance and swipe a card again at the exit.
Installation Considerations
1. There are distance limitations for Wiegand and RS-485 communications. Please note:
• Wiegand interface: 30 meters (98.43 feet)
• RS-485 interface: 600 meters (1968.50 feet)
• Recommended cable: standard 485 cable (a twisted pair of 24 AWG wires)
2. GV-ASManager software is used to manage GV-AS100/GV-AS110/GV-AS400 Controllers.
There is a limit for the number of controllers connected to GV-ASManager based on
communication modes.
• Through the network, up to 255 GV-AS100/GV-AS110/GV-AS400 Controllers can
connect to GV-ASManager.
• Through RS-485 connection, up to 16 GV-AS100/GV-AS110 Controllers can connect
to the same COM port on a computer running GV-ASManager.
