WARNING: Disconnect all power to the unit before
installing Plug-in cards.
Adding Option Cards
The PAX and MPAX series meters can be fitted with up to three optional plug-
in cards. The details for each plug-in card can be reviewed in the specification
section below. Only one card from each function type can be installed at one time.
The function types include Setpoint Alarms (PAXCDS), Communications
(PAXCDC), and Analog Output (PAXCDL). The plug-in cards can be installed
initially or at a later date.
COMMUNICATION CARDS (PAXCDC)
A variety of communication protocols are available for the PAX and MPAX
series. Only one of these cards can be installed at a time. Note: For Modbus
communications use RS485 Communications Output Card and configure
communication (

) parameter for Modbus.

UNITS LABEL KIT (PAXLBK)
Each meter has a units indicator with backlighting that can be customized
using the Units Label Kit. The backlight is controlled in the programming.
PROGRAMMING SOFTWARE
The Crimson
®
2 (SFCRM2) software is a Windows
®
based program for
configuring and updating the firmware of the PAXDP meter from a PC. Using
the software makes programming the PAXDP meter easier and allows the user
to save the PAXDP database in a PC file for future use. The software is available
as a free download from Red Lion’s website.
The first time Crimson 2 software is run from the File menu, select “New” to
display a dialog and select the PAXDP. The screen will display icons that
represent the various programming sections of the PAXDP. Double-click on an
icon to configure the programming parameters pertaining to the selection. Tool
Tip help is available for each of the program parameters. A PAX serial plug-in
card or PAX USB programming card is required to program the meter using the
software.
When communicating with Crimson 2 software, the PAXDP must be set in
default configuration type of:
Communications Type: MODBUS RTU
Baud Rate: 38400
Data Bit: 8
ParityBit: no
Meter Unit Address: 247
