3.0 CONFIGURATION
The Model 1226 is simple to install, and is designed for excellent
reliability: just set it and forget it. The following instructions will help
you set up and install the Model 1226 properly. If you have any
questions, please call Patton Technical Support at (301) 975-1007.
3.1 CONNECTING TWO MODEL 1226s
(Parallel to Parallel)
The Model 1226 uses a set of eight DIP switches (see Figure 1)
that allow configuration to a wide range of applications. Because all
eight switches are in one externally accessible DIP switch package,
there is no need to open the Model 1226's case for configuration. The
configuration switches allow you to select data rates, parity, word length
and flow control selection. The following section describes all switch
locations, positions and functions.
The Model 1226 uses a DIP switch package (see Figure 2). To
configure your unit, use a small screwdriver and gently push each
switch to its proper setting. The ON and OFF positions are shown in
Figures 1 and 2.
