32 AC-215IP Hardware Installation Manual

The RS-232 connection can only connect a single access control panel to the

computer.

The distance between the computer and the access control panel must be no

more than 150 feet (50 meters).

If the baud rate is increased to 57600 or beyond, the distance must be no

more than 30 feet (10 meters).

6.1.2 RS-485 Connection to the Computer

Set the J1 switch to the RS-485 position.

Up to 32 access control panel's can be linked together and connected to a

single communication port on the computer.

Use the RS-485 interface for situations where there are multiple controllers

connected. The serial port used to control the access control panel is assigned

within the AxTraxNG™ software.

The access control panel supports the two-wire RS-485 interface. RS-485

interface enables the distance between the Access control panel and PC to be

extended up to 4000 feet (1219) meters. The data line wiring must be in daisy

chain formatting with one control unit following another. The first Access

control panel connecting to the PC must use the MD-14 RS-485 to RS-232

adaptor.

6.1.3 Daisy Chaining

Daisy chaining allows many panels to connect to the computer along a single

serial line.

The first panel is connected directly to the computer and a second panel

connects to the first panel. Additional panels connect in the same way, one

after another.
