2. INSTALLATION
In most cases, installation consists of simply
connecting the appropriate cable between the
OmniLink 5000 OIT and the feed. Exceptions to
this are noted in the sections for each feed.
There are two different communication boards
used on the OmniLink 5000. The older style board
only supports certain feeds and provides for the
downloading of tonnage waveforms. The newer
communications board supports more feeds, user
selectable units for the feeds (for instance, inch and
millimeter), tonnage waveform downloads, network
operation, and other planned future enhancements.
OmniLink controls shipped after July 1998 have the
newer communications board installed as standard.
If the features of the newer communications board
are desired for an OmniLink control with the older
board installed, a retrofit kit is available to upgrade
the control. Contact Link for details and pricing.
The connection to the OmniLink OIT
depends on whether the old or new communication
board is installed. Sections 2.1 and 2.2 show which
port to use on each kind of communication board.
2.1 Old Communication Board Connection
The older communication board has 4
connectors and looks like figure 2.1 as viewed from
the back panel of the OmniLink OIT.

communications board
For this board, serial port #1 (see figure 2.1) is
intended for use with electronic roll feeds. This
interface conforms to RS-232C specifications. Data
is transmitted and received as ASCII characters with
1 start bit, 8 data bits, 2 stop bits, no parity, full
duplex, and 9600 baud.
2.2 New Communication Board Connection
The new communication board has 5 connectors
and looks like figure 2.2 as viewed from the back
panel of the OmniLink OIT.
