Sub-Menu Item Description
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 denitions include:
Address Denition
0 Disable Modbus interface.
1–127 Enable Modbus interface on RS-232 port.
128–255 Enable Modbus interface on RS-422 port.
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 “Conguring the
Hardware for Digital Communication” in Chapter 3.
Baud Serial communication baud rate. Options include:
• 9600 (system default)
• 4800
• 2400
• 1200
I1L On the rst analog output – V/I #1 – this is the low-scale (minimum) WDP temperature (°C or °F) cor-
responding to the 4.00 mA output.
Note: This parameter will be displayed only if an external water signal is provided
and if the H2O DP:EXT option is enabled from the MonitorCFG menu.
I1H On the rst analog output – V/I #1 – this is the full-scale (maximum) WDP temperature (°C or °F) cor-
responding to the 20.00 mA output.
Note: This parameter will be displayed only if an external water signal is provided
and if the H2O DP:EXT option is enabled from the MonitorCFG menu.
I2L On the second analog output – V/I #2 – this is the low-scale (minimum) HCDP temperature (°C or °F)
corresponding to the 4.00 mA output.
I2H On the second analog output – V/I #2 – this is the full-scale (maximum) HCDP temperature (°C or °F)
corresponding to the 20.00 mA output.
I3L On the third analog output – V/I #3 – this is the low-scale (minimum) WCT – mg/m
3
(lb/MMcf), PPMV,
or PPMW – corresponding to the 4.00 mA output.
Note: This parameter will be displayed only if an external water signal is provided
and if the H2O CT:EXT option is enabled.
I3H On the third analog output – V/I #3 – this is the full-scale (maximum) WCT – mg/m
3
(lb/MMcf), PPMV,
or PPMW – corresponding to the 20.00 mA output.
Note: This parameter will be displayed only if an external water signal is provided
and if the H2O CT:EXT option is enabled.
I4L The fourth analog output – V/I #4 – is reserved for the low-scale (minimum) pressure (KPA or PSI)
corresponding to the 4.00 mA output. This analog output is currently not used.
I4H The fourth analog output – V/I #4 – is the full-scale (maximum) pressure (KPA or PSI) corresponding
to the 20.00 mA output. This analog output is currently not used.
Chng PSCD1? This prompt asks if you wish to change Passcode1. To change the password for the ApplicCFG menu,
enter a new 4-character code, using any combination of the , ‘+’, and ‘–’ buttons. After entering the
password, “Chng PSCD1?” will be displayed again. Enter the passcode a second time.
Save AppCFG? This prompt asks if you wish to permanently save the changes you made to the ApplicCFG param-
eters. To save any changes you made, press the ‘+’ button. If the changes are not saved, they will
remain in eect until the analyzer is powered down or reset.
