Module
LonPoint DO-10 Digital Output Module
The front panel of the DO-10 module is shown in figure 7.1. There are no user-
configured jumper blocks on the DO-10 module. The front panel of the module
includes four three-position hand/off/auto switches that permit the user to force an
output to an ON or OFF state, or to allow the network to select the output state.
The switches force the output low (0 position) or high (1 position), or allows the
application program to select the output state (center network position). A separate
front panel LED is provided for each output.
The four hand/off/auto switches control the outputs of the DO-10 as long as the
module is powered, regardless of the software state of the module. The four status
LEDs will track the state of the outputs only if the application program is running
and the module is in the configured state. The status LEDs will not fuction if the
module is in an unconfigured state.
