Communications
Communication lines are used to upload and download information between
the access control panel and the AxTraxNG 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
The access control panel address is defined in the AxTraxNG 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 AxTraxNG software. The default bitrate is 9600 bps 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 connection if
you wish to connect additional panels to the primary control panel already
connected to the COM port.
The J1 switch must be in the correct position to select the RS-232
communication.
6.1.1
RS-232 Connection to the Computer
Set the J1 switch/jumper to the RS-232 position.
The RS-232 connection can only connect a single access control panel to the
computer (Figure 16).
