USB
This port can be used for instrument communication and is also good for quickly downloading data,
onsite diagnostics, maintenance and firmware upgrades.
TCP/IP (optional)
This port is best used for remote access and real-time access to instruments when a network is
available to connect with.
External I/O Port
The analog/digital port sends and receives analog/digital signals to other devices. These signals are
commonly used to activate gas calibrators or for warning alarms.
Analog Outputs
The analyser is equipped with three analog outputs. Menu selectable as either voltage output
0-5VDC, or current output 0-20, 2-20, 4-20 mA.
Analog Inputs
The analyser is also equipped with three analog voltage inputs (0-5VDC CAT 1) with resolution of 15
bits plus polarity.
CAUTION
Exceeding these voltages can permanently damage the instrument and void the
warranty.
Digital Status Inputs
The analyser is equipped with 8 logic level inputs (0–5VDC CAT 1) for the external control of
zero/span calibration sequences.
CAUTION
Exceeding these voltages can permanently damage the instrument and void the
warranty.
Digital Status Outputs
The analyser is equipped with 8 open collector outputs which will convey instrument status
conditions and warning alarms such as no flow, sample mode, etc.
CAUTION
Exceeding 12VDC or drawing greater than 400mA on a single output or a total
greater than 2A across the 8 outputs can permanently damage the instrument
and void the warranty.
