LNL-3300 Intelligent System Controller
33
Installation
To install the ISC, perform the installation procedures described in the following sections, in the order in
which they are presented.
1.
Wire the device for communication.
2.
Supply power to the controller and wire the unsupervised alarm inputs for power fault and cabinet
tamper monitoring.
3.
Remove the plastic safety strip from the memory backup battery.
4.
Configure the correct settings using the jumpers and DIP switches.
5.
Set the board for the desired initial IP addressing mode.
6.
Configure the network and port settings using the embedded web server.

Communication Wiring
The controller communicates to the host via: onboard Ethernet 10Base-T/100Base100-TX port or on port 1.
Dual path communication from the host to the LNL-3300 is supported. Port 1 may be configured as RS-232,
2-wire RS-485 or optional Lantronix Ethernet 10baseT/100Base-TX CoBox-Micro interface. RS-232
interface is for direct one to one connection to a host computer port or a modem, 50 feet maximum.
PORT 1 CONFIGURED
There are a few options for establishing communication to configure the settings for the first time. For initial
configuration prior establishing a LAN connection, a CAT 5 crossover cable can be used to connect directly
to a PC. In this scenario, the controller has a static IP address and the web browser-enabled PC is connected
directly to the controller using a crossover cable.
Ports 2 and 3 utilize 2-wire RS-485 interface only. The interface allows multi-drop communication on a
single bus of up to 4000 feet (1,200 m). Use twisted pair (minimum 24 AWG) with shield for the
communication with 120 ohm impedance. Install termination jumpers only at the end of line unit.
