Balance between leds is adjusted by changing the intensity of red/infrared. Intensity of infrared (
Ired int.
) is in
the range of 40 to 255 and red intensity (
red int.
) is in the range of 40 to 255.
DC gain
shows the gain of DC signal adjusted by the module.
IDC
is the value of infrared signal.
RDC
is the dc value of red signal.
AC gain
is the gain of infrared and red ac signals. AC gain values can be 1 or 0. Value 1 means high ac gain
and 0 means low gain.
Pre gain
is a preamplifier gain for infrared and red signals. Pre gain values can be 1 or 0. Value 1 means
normal operation. Value 0 means that signal levels are very low and extra gain is taken into use.
Temp error
shows the status of the temperature test. No errors found show the status (OFF) and errors found
(ON).
Protect key
shows normally OFF, but turns to ON when the button at the bottom of the module is pressed.
Protect mode
is normally ON.
It turns to OFF, when Protect is switched to OFF for the temperature calibration
in Calibration Menu.
Configuration
shows the chosen module configuration: TP, ST, or STP.
Timeouts
is a cumulative number that indicates how many times the module has not responded to the the
monitor’s inquiry.
Bad checksums
is a cumulative number that indicates how many times communication from the module to
the monitor has broken down.
Bad c-s by mod
is a cumulative number that indicates how many communication errors the module has
detected.
The monitor starts counting these items at power up and resets to zero at power off. The values may also be
reset when a module is attached to the monitor frame and be set to 32769 or continuous counting may be
started when the module is removed from the monitor frame.
The nonzero values do not indicate a failure, but the continuous counting (more than 5 per second) or value
32769 indicates either a serial communication failure or a module not in place. Also failures in other modules
may cause these numbers to rise or be set to 32769.
RAM
indicates the state of the RAM memory.
ROM
indicates whether the checksum at the EPROM is in accordance with the one the software has
calculated.
EEPROM
indicates if the values stored in the permanent memory are valid.
The state is either
OK, Fail
or
?
(module not in place or a communication error).
