Document Introduction
This document describes the subnetwork for the LN Series Input/Output Extension
Modules used with the LN Free Programmable PRG 600 Series Controllers. The
LN Free Programmable PRG 600 Series Controllers use the subnetwork to support
one or more extension modules with structural cabling. This document does not
describe how to set up a LONWORKS® network. For information on setting up your
LONWORKS® network, refer to the LONWORKS LN-Series Network Communication
and Interface Guide Technical Bulletin (LIT-12011253).

Subnetwork
Figure 1 shows the LN Series Input/Output Extension modules on the
subnetwork with the proper End-of-Line (EOL) terminations.
Figure 1: EOL Terminations Settings on Subnetwork
Topology and EOL Terminations
Set the EOL terminations on the LN Free Programmable PRG 600 Series
Controller and the last LN I/O Extension Module to ON. All other extension
modules must have their EOL termination set to OFF (Figure 1).
Note: In Figure 1, the EOL jumpers are located on the inside of the controller and
modules.
Subnetwork Length
The total maximum length of the subnetwork is 300 meters (1,000 feet). The
polarity of the LN Series I/O Extension Modules must be configured as shown in
Figure 2. All terminals identified as SUBNET+ must be connected to the same
conductor. Similarly, all terminals identified as SUBNET- must be connected to the
same conductor.

4 LN Series Input/Output (I/O) Extension Modules Subnetwork for LN-PRG6x0-2 Application Note
Use properly grounded, shielded cable for the best protection against interference
on the LN Series I/O Extension Module subnetwork. Use the daisy-chain
configuration with the cable shield twisted together and isolated with electrical
tape at each extension module.
When you use an LN Free Programmable PRG 600 Series Controller, connect the
shielding of the extension modules on the subnetwork to the electrical system
ground at one point only (Figure 2).
Physical Specifications and Cable Requirements
Use cables composed of stranded conductors, instead of solid conductors, for the
best breakage resistance during pulling operations. Table 2 describes the physical
specifications and cable requirements for an LN Series I/O Extension Module
subnetwork.

Addressing
Each LN Series I/O Extension Module on the subnetwork must have a unique
address. The current valid addresses are 1 or 2. Figure 3 shows an example of how
to set a DIP switch. Table 3 shows the DIP switch settings.
