6.2 TCP/IP Network Connection
This section applies to the AC-225IP models only.
The computer running the AxTraxNG software can communicate with the access
control panels via a TCP/IP network. The connection settings are controlled within
the AxTraxNG software.
The AC-225IP panels connect to the TCP/IP network (LAN or WAN) directly, using
an onboard network module. For each AC-225IP panel connected on a TCP/IP port,
up to 31 subnetworked panels can be connected via an RS-485 bus, which means
that one IP port can support up to 32 AC-225x-B panels (Figure 20).
Figure 20: Connecting Multiple Access Control Panels to AC-225IP
To connect to a TCP/IP network using AC-225 non-IP models, add Rosslare's MD-
N32 TCP/IP to RS-232 gateway converter.
For more information on operating an MD-N32, refer to the MD-N32 User Manual.
6.2.1 LAN and WAN Requirements
The devices can be connected to a TCP/IP network using any valid network
address.
Use a TCP/IP connection when a LAN network already exists. Figure 21 illustrates
the connection of a single AC-225x-B to a computer via a LAN network.
