Refer to Table 2 to identify the proper jumper settings for
your application’s communications configuration. Position
the jumpers as needed on the module. Figure 9 shows the
locations of the jumpers on board the module.
When shipped from the factory, no jumpers are installed on
E131, E132, E133, E231, E232 and E233. For multidrop
configurations you will need two jumpers for each port (such
as E131 and E133 for port 1). The default factory settings
include jumpers positioned at E104, E106, E114, E116, E124,
E126, E204, E206, E214, E216, E224, and E226. These
jumpers connect termination, pull-up and pull-down resistors
for the CTS and DSR signal pairs for port 1 and 2. Since the
CTS and DSR signals are not actually used by the module,
you can remove jumpers installed at any of these positions in
order to install them as needed for E131, E132, E133, E231,
E232 or E233.
