Communications

6. Communications

Communication lines are used to upload and download

information between the access control panel and the

VeriTrax AS-225 software. When the access control panel and

the computer are communicating,

the system’s two LEDs flash

accordingly.

• The RX LED flashes when the controller receives data

• The TX LED flashes when the controller transmits data

Note:

The access control panel address is defined in the

VeriTrax AS-225 software.

It is important that the DIP switch and the software are set

to the same address.

There are three connection modes:

• Serial Network (RS-232 or RS-485)

• Modem Network

• TCP/IP Network

6.1 Serial Network Connection

The computer serial port controlling the access control panel is

set from within the VeriTrax AS-225 software. The default is

9600bps for direct connection to the computer.

When using an RS-232 connector, only one access control

panel can be linked to each communication port on the

computer. Use an RS-485 if you wish to connect more than

one panel on one communication port.

Note:

The J1 switch must be in the correct position to select the

RS-232 communication.
