Model 9110T NOx Analyzer				Getting Started
Table 3-3:		Rear Panel Description
	Component		Function
		cooling fan	Pulls ambient air into chassis through side vents and exhausts through rear.
		AC power	Connector for three-prong cord to apply AC power to the analyzer.
		connector	CAUTION! The cord’s power specifications (specs) MUST comply with the power
			specs on the analyzer’s rear panel Model number label
	Model/specs label		Identifies the analyzer model number and provides power specs
		TO CONV	(not used)
		FROM CONV	(not used)
		MULTI	(not used)
		TO DRYER	(not used)
		FROM DRYER	Outlet for internal sample gas dryer; connect to external zero air scrubber (for IZS options
			only).

SAMPLE	Connect a gas line from the source of sample gas here.
	Calibration gases can also enter here on units without zero/span/shutoff valve options
	installed.
EXHAUST	Connect an exhaust gas line of not more than 10 meters long here that leads outside the
	shelter or immediate area surrounding the instrument. The line must be ¼” tubing or
	greater.
SPAN 1	On units with zero/span/shutoff valves option installed, connect a gas line to the source of
	calibrated span gas here.
SPAN2/VENT	On units with pressurized span valve option, used for venting.
ZERO AIR	Internal Zero Air: On units with zero/span/shutoff valves option installed but no internal
	zero air scrubber attach a gas line to the source of zero air here.
RX TX	LEDs indicate receive (RX) and transmit (TX) activity on the when blinking.
COM 2	Serial communications port for RS-232 or RS-485.
RS-232	Serial communications port for RS-232 only.
DCE DTE	Switch to select either data terminal equipment or data communication equipment during
	RS-232 communication.
STATUS	For ouputs to devices such as Programmable Logic Controllers (PLCs).
ANALOG OUT	For voltage or current loop outputs to a strip chart recorder and/or a data logger.
CONTROL IN	For remotely activating the zero and span calibration modes.
ALARM	Option for concentration alarms and system warnings.
ETHERNET	Connector for network or Internet remote communication, using Ethernet cable
ANALOG IN	signalsOption for external voltage signals from other instrumentation and for logging these
USB	Connector for direct connection to laptop computer, using USB cable.
Model Label	Includes voltage and frequency specifications
