MICROTEL Series 1000 Dialer
40
Site Control
The Series 1000 makes it possible to immediately begin equipment maintenance before
arriving at a remote site, or teleservice a physical process. Use the following touch-tone
commands to actuate digital outputs or control analog outputs over the telephone. An
example use would be turning a pump on or off when responding to an alarm call from
the dialer, or adjusting a variable-speed output device to control a measured parameter.
z Controlling Digital Outputs When a channel’s I/O Type is Digital Output (*c2,
**c203, see Section Configuring Input/Output Modules for more details), the user
can set the output state by entering the proper touchtone command.
*c6
Report I/O channel c Digital Output status
**c60 Program Digital Output channel c to be OFF
**c61 Program Digital Output channel c to be ON
There are two types of Digital Outputs: Latched and Momentary. A Latched
Output will maintain the last state the user commanded. A Momentary Output will
cause the output to close for this channel’s On Delay Time (*c5, **c51MMSS, see
Section I/O Channel ON/OFF Delay), then reopen.
To make a Digital Output Momentary, the command is **c80. To make this Output
Latched (Default), the command is **c81. To make this Output Latched and to
remain in this output state even after the dialer’s power has cycled, the command is
**c85.
Before using **c85, make sure that this fits your application. Use this feature
with caution since just the action of turning on a dialer can cause a pump to run.
Example-
Command: **161
Response: Channel one output is ON.
Example- Command: **160
Response: Channel one output is OFF.
NOTE: If this command doesn’t seem to control the output, make sure that the
channel’s Type is Digital Output (See I/O Channel Type (*c2, **c203).
z Setting An Analog Output This setpoint directly controls an analog output value
where “aaa” represents the analog value in percent from 0% to 99.9% (aa.a%).
*c92 Report I/O channel c analog output setpoint
**c92aaa Program I/O channel c analog output setpoint
Example- Command
**292250
Response: Channel two analog output is two five point zero percent.
