36 AC-225x-B Series Hardware Installation and User Manual
The maximum distance from the Ethernet port of the panel to the LAN/WAN
connection is 100 m (330 ft).
When the TCP/IP connection is implemented over a WAN, it becomes possible to
connect through the Internet. This makes it possible to control multiple access
control panels worldwide, all from a single computer.
Before connecting a panel by TCP/IP connection for the first time, the AxTraxNG
software must configure the device. Settings then remain stored in non-volatile
memory on the device (see the AxTraxNG Software Manual).
When using an MD-N32, for a single panel, either an RS-232 cable or Rosslare's
MD-14U RS-485 to RS-232 converter can be used.
To connect an MD-N32 to more than one panel (up to 32 panels), Rosslare's MD-
14U RS-485 to RS-232 converter must be used. Connect the MD-14U between the
RS-485 access control panel network and the MD-N32 converter (Figure 22).
