Sub-Menu Item Description
UsrRelay User-selectable relay type (Relay 4). Upon instructions from the customer, AMETEK can
configure Relay 4 (and LED 4) at the factory to indicate, when turned On, either:
• NoD = Hydrocarbon Dewpoint Temperature Not Found.
or
• Pur = Purging/Hold Stage Is In Progress (typically used for Data Acquisition Systems (DAS)
Note:
UsrVI User-selectable V/I type (Analog output 4). The only option currently available is:
• SCode = basic Status Code [if H2O DP:DISAB option is enabled from the MonitorCFG
Net This parameter allows you to select the Network communications type. Options include:
• S2K = System 2000 (Communicating via System 200 Configurator Software). For details
• MODBUS = Communicating via Modbus.
MB Addr z Modbus slave address, used to select a port that will allow communications between a
computer and the analyzer, where 'z' is a number between 0–250. The definitions include:
Comm Serial communication type. Options include:
• RS232 (system default)
• RS422
• 4WRS485 (4-wire RS-485)
• 2WRS485 (2-wire RS-485)
After selecting the desired serial communication type,
several jumpers on the CPU board may need to be changed in order to establish
communication. See jumper settings listed under "Configuring the Hardware for Digital
Communication" in Chapter 2.
Baud Serial communication baud rate. Options include:
• 9600 (system default)
• 4800
• 2400
• 1200
I1L On the first analog output – V/I #1 – this is the low-scale (minimum) WDP temperature
(°C or °F) corresponding to the 4.00 mA output.

If the User Relay is configured to indicate NoD, the condition is updated at the end of each
Cooling Stage. The result is used to interpret the temperature on the analog output signal
channels.
or other remote systems).
If the User Relay is configured to indicate Pur, the relay will be activated at the beginning of
the Purging/Hold Stage and deactivated at the end of the Purging/Hold Stage. This function
indicates to remote DAS systems that new data is present on the analog output channels.
While this function is typically configured by AMETEK at the factory, the User
Relay can be changed from the ApplicCFG menu.
