Setting the Module Jumpers
There are seven jumpers (J8) located on the PC board of this module. The description of each
jumper’s function is also located on the PC board. These jumpers configure the module for
the following options:
• Number of channels: 1 thru 4.
• The input type: 10

RTDs.
• Temperature conversion: 2’s complement or mag sign format in Fahrenheit
or Celsius.
There are two channel selection jumpers, labeled CH+1 and CH+2, that are used to select the number
of channels that will be used. The module is set from the factory for four channel operation. Any
unused channels are not processed, so if you only select channels 1 thru 3, channel 4 will not be active.
The following table shows how to use the jumpers to select the number of channels. Unused
jumpers can be stored on a single post to prevent losing them.
