Pulls ambient air into chassis through side vents and exhausts through rear.
Connector for three-prong cord to apply AC power to the analyzer.
CAUTION! The cord's power specifications (specs) MUST comply with the power
specs on the analyzer's rear panel Model number label
Identifies the analyzer model number and provides voltage and frequency specs
Connect a gas line from the source of sample gas here.
Calibration gases are also inlet here on units without zero/span/shutoff valve options
installed.
Connect an exhaust gas line of not more than 10 meters long here that leads outside
the shelter or immediate area surrounding the instrument.
On units with zero/span/shutoff valve options installed, connect a gas line to the source
of calibrated span gas here.
Used as a second cal gas input line when instrument is configured with zero/span
valves and a dual gas option, or as a cal gas vent line when instrument is configured
with a pressurized span option
Internal Zero Air: On units with zero/span/shutoff valve options installed but no internal
zero air scrubber attach a gas line to the source of zero air here.
LEDs indicate receive (RX) and transmit (TX) activity on the when blinking.

Serial communications port for RS-232 only. (Sections 3.3.1.8, 5.7, 6.3, 6.7.2.1)
Switch to select either data terminal equipment or data communication equipment
during RS-232 communication. (Section 6.1).
For ouputs to devices such as Programmable Logic Controllers (PLCs). (Section
3.3.1.5).
For voltage or current loop outputs to a strip chart recorder and/or a data logger.
(Sections 3.3.1.3 and 3.3.1.4).
For remotely activating the zero and span calibration modes. (Section 3.3.1.6).
Option for concentration alarms and system warnings. (Section 3.3.1.7).
Connector for network or Internet remote communication, using Ethernet cable
(Section 3.3.1.8).
