Linear LIN-501C User Manual

Am-sek / lin-501c quick start guide, Overview, Network issues

Overview

The AM-SEK Kit includes a LIN-501C Serial-to-Ethernet Module that
provides a standard network TCP/IP connection for Linear’s AM3Plus,
AE1000Plus, and AE2000Plus access controllers. The module can be
used as an alternative to a traditional telephone modem typically used
for remote access to Plus panel controllers.
The LIN-501C module connects between the Plus panel’s RS-232 Serial
port and the installation’s Local Area Network (LAN). Access to the panel
can be locally through the LAN or remotely from the Wide Area Network
(WAN). Typically the module is connected to a port on a router located on
the installation’s LAN.
In Plus panel networks, with multiple panels interconnected via
RS‑485 wiring, the LN‑501C module connects to Node #1 of an
AXNET network, or Node #1 of any AccessBase2000 network.
The LIN-501C does not replace the RS-485 and modem connections in a
multiple access panel network. It does enable using an Ethernet network
connection (instead of a direct serial connection or modem) between
a Windows PC and supported Linear access panels to access and
configure the panels using AXNET and/or AccessBase2000 applications.
For easy configuration and setup, Windows

based software utilities are

included on the installation CD. The utility software is used for setting up
the LIN-501C module’s IP address and the computer’s virtual COM ports.
The utility software is compatible with Windows XP

, Windows Vista

, and

Windows 7

®.

To help with the module and router network configuration,

a log sheet is provided to document the installation settings.

Network Issues

Computer network topologies range from simple to complex. These
instructions outline installation for a basic local area network. Large and
complex networks may require setup that is beyond the scope of these
instructions. If setup issues arise while configuring the LIN-501C module,
seek assistance from the IT professional responsible for maintaining the
network.

Programming PC Overview

At the installation site, a programming PC needs to be connected to the
Local Area Network. This PC can be a permanent one in the installation,
or can be a temporary PC brought in by the installer.
Administrator access will be required to setup the virtual COM ports on
the PC. The virtual COM ports are assigned the IP address and port
number of each LIN-501C module.
If AccessBase2000 is used to manage the access network, it needs
to be installed on the management PC.

To avoid overwriting the

installation’s database, don’t run AccessBase2000 remotely on a
separate setup PC.
If AXNET is going to be used to manage the access network, the PC will
use a Windows direct connect network connection to communicate with
the access network. Refer to Page 5 of AXNET manual P/N 226505 for
details on setting up the Windows direct connect network connection.

Module Installation

1. Mount the LIN-501C module in a secure and weather protected location.
2. Connect the modular jack end of the A2C-DB9 cable to the RS-232

Port of the Linear “Plus” panel.

3. Connect the DB9 connector end of the A2C-DB9 cable to the COM

port on the LIN-501C module.

4. Connect a CAT-5 network cable between the LAN connector on the

LIN-501C module and an open port on the Local Area Network’s
router (300 foot cable length maximum).

5. Route the wire from the power supply and connect the power supply

cable RED (+) and BLACK (-) terminals on the plug-in terminal block.
Plug the terminal block into the module.

6. Repeat Steps 1-5 for each additional LIN-501C module installed for

different access networks in the installation.

7. When power is applied, a module’s RUN indicator should light and

the LAN indicator should flash.

Communicating with the Access Network

Local Connecting with AccessBase2000

After opening the AccessBase2000 application, go to the network
settings screen and set each active network to connect using the virtual
COM port number (COM2 - COM8) that was setup to communicate with
its LIN-501C module.

Local Connecting with AXNET

Create a Windows direct connect network when setting up for AXNET
communications. Be sure to select the virtual COM port number assigned
to the LIN-501C module for the “Communications Cable Between Two
Computers” setting. Be sure to configure the port speed to 38400 bps.

Remote Connecting with AccessBase2000

✓

NOTE: In existing installations, it is not recommended to
connect with AccessBase2000 remotely on a separate setup
PC. The installation’s database in the local PC could get
overwritten, causing LOSS OF ALL CARDHOLDER DATA and
other programming! Always backup installation data!

Remote Connecting with AXNET

Create a Windows direct connect network when setting up for AXNET
communications. Be sure to select the virtual COM port number that was
setup to communicate with the router’s external IP address and module’s
public port number. Be sure to configure the port speed to 38400 bps.
After the network connection is made and connected, use an Internet
Web browser to connect to the AXNET panel.

Using Ping to Test IP Addresses

1. From the Windows START menu, select RUN.
2. Enter COMMAND (or CMD) into the OPEN: field and press OK. The

DOS command prompt window will open.

3. To test an IP address enter PING and the IP address.
4. If the Ping command displays “Request timed out.” the IP address

is not currently used. The address

can be assigned to a LIN-501C

module.

5. If the Ping command displays replies from the IP address, the

address is already being used by a device and

cannot be assigned

to a LIN-501C module.
