NT4 Configuration Worksheet
The following configuration procedure and worksheet are provided to
help you configure each of the channels on your thermocouple
module.
Channel Configuration
Procedure
The channel configuration word consists of bit fields, the settings of
which determine how the channel will operate. This procedure looks
at each bit field separately and helps you configure a channel for
operation. Refer to chapter 5 as needed to complete the procedures in
this appendix or you may prefer to use the summary worksheet on
page B-4.
1. Determine the input device type for a channel and enter its
respective 4-digit binary code in bit field 0-3 of the channel
configuration word.
2. Select a data format for the data word value. Your selection
determines how the analog input value registered by the analog
sensor will be expressed in the data word. Enter your 2-digit
binary code in bit field 4-5 of the channel configuration word.
