Open CTM (Revision D)

Command Reference

n = 1 to 6 input channel number

d = A set as analog input

d = D set as digital input

x.x = 0 to 9.9 sets the voltage threshold for alarm reporting (valid if input set as analog only, use 0.0 for

digital input)

p = P sets input polarity to positive (this also determines the alarm level)

p = N sets input polarity to negative (this also determines the alarm level)

a = 0 alarm off

a = 1 alarm on

a = 2 alarm on change state (valid for digital inputs only)

The current setup can be queried by using the insetup without parameters.

Note: When configuring insetup with a digital input, the voltage threshold parameter is ignored. The

modem's I/O module has fixed digital input thresholds of 3 V and 2 V (1 V hysteresis).

Examples:

1. Set input #2 as digital, with alarm when ON

cmd insetup 2 D 0.0 P 1

2. Set input #4 as analog, with alarm when > 7.5V

cmd insetup 4 A 7.5 P 1

3. Query the setup parameters for all 6 inputs

cmd insetup

cmd insetup 1 A 0.0 N 0

cmd insetup 2 A 0.0 N 0

cmd insetup 3 A 0.0 N 0

cmd insetup 4 A 0.0 N 0

cmd insetup 5 A 0.0 N 0

cmd insetup 6 A 0.0 N 0

A cmd save is required for this command to take effect.
