Chapter 3 Module Data, Status, and Channel Configuration

Channel Configuration

Each channel is independently configured via a group of eight

consecutive words in the Configuration Data file. The first two words

of the group consist of bit fields, the settings of which determine how

the output channel operates. See the tables below and the

descriptions that follow for valid configuration settings and their

meanings. The default bit status of the configuration file is all zeros.
