Analog Meter Inputs
Analog measurement capability consists of an 8 channel 10 bit analog to digital converter. Each channel is capable of measuring
voltages between 0 and approximately 5 volts DC and may be programmed to reflect actual values. With the proper sensor hardware
(see the RC210 Hardware Manual for details), the range of measurement can be anything you need it to be and not only those limited
to this range.
Signals may be provided from the receiver s meter and deviation metering circuits, from wattmeters, temperature sensors and other
transducers. There are a number of meter face names you can use, including Volts, Amps, W atts, Degrees, Miles per Hour, and
Percent. Scaling of these meter faces is completely programmable by the owner.
The voltage from an external sensor is applied to one of the Analog to Digital (A/D) inputs and measured. Then based on how that
meter channel is programmed, the RC210 speaks the measured value. For example, if you have Meter 1 programmed to read
temperature, the controller will speak the value in "Degrees".
When a meter readback command is entered, the controller reads back a value that represents the average of several measurements
taken over the past few seconds. As the A/D measurements are taken every second and smoothed in the controller firmware, this
provides for a very stable reading. For maximum accuracy, the reference voltage used by the A/D converter is programmable.
High and low values for each Meter are stored and can be read back by the user on command. This allows for tracking of trends and
each high and low value can be cleared using a command for each meter, or by a global command to clear all the stored high and low
values with one command.
How to setup Meters and how to calibrate them is explained later in the Programming section of this manual

Readback current value
1400 (channel 1 - 8)

Readback stored LOW value
1400 (channel 1 - 8)
2
Readback stored HIGH value
To reset a meter's High/Low Stored value:
1500x
where "x" is the Meter 1 - 8 channel you wish to clear. Entering a 0 will clear all channels.
Meter Alarms
Each of the Meter Inputs has programmable high and low alarms which when tripped will run a Command Macro. See the Programming
section of this manual for details.
Each of the 8 Meter Alarms may be enabled and disabled. To enable or disable a meter alarm:
1600xy
where x = 1 to 8 for the meter channel and y = 1 for ON and 0 for OFF
Disabling a Meter Alarm retains that alarm's programming but causes it to be ignored even if "tripped".
Logic Alarms
Each Alarm may be individually turned ON, OFF or interrogated. While enabled, an alarm is triggered by 2 different event
– its input line
transitioning from a logic high to a logic low and from a logic low to a logic high. Each state may be programmed to call its own
Command Macro. See the Programming Reference section for details about programming the Alarms. You may also interrogate the
logic state of each Alarm, which is handy for troubleshooting and setup.
