AC-215IP Hardware Installation Manual 33

At each end of the data line, both where the panel connects to the computer

and on the last panel in the network, a termination resistor of 120 Ω may be

required. Apply the resistor across the L1 and L2 connections.

These termination resistors are especially important in long cable runs.

6.2 TCP/IP Network Connection

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.

AC-215IP panels connect to the TCP/IP network (LAN or WAN) directly, using

an on-board network module. When an access control panel network is

connected using RS-485, up to 32 panels can be connected on each TCP/IP

network. This means that one AC-215IP panel can support up to 31 AC-

215/225/425 panels.

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 and the long RS-

485 network is not required. The following schematic illustrates the connection

of a single AC-215IP to a computer via a LAN network.

When the TCP/IP connection is implemented over a Wide Area Network (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 Software Manual configuring

instructions).

When using an MD-N32, for a single panel, either an RS-232 cable or

Rosslare's MD-14 RS-485 converter can be used.

To connect an MD-N32 to more than one panel (up to 32 panels), Rosslare's

MD-14 RS-485 converter must be used. Connect the MD-14 between the RS-

485 access control panel network and the MD-N32 converter.
