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.

PAXI 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. When programming

the unit via Crimson, a Windows® based program, the RS232, RS485 or USB

Cards must be used. Note: For Modbus communications use RS485

Communications Output Card and configure Communication Type parameter

(tYPE) for Modbus.

PROGRAMMING SOFTWARE

Crimson software is a Windows® based program that allows configuration of

the PAX meter from a PC. Crimson offers standard drop-down menu commands,

that make it easy to program the meter. The meter's program can then be saved

in a PC file for future use. A PAX serial plug-in card or PAX USB programming

card is required to program the meter using the software.

SETPOINT CARDS (PAXCDS)

The PAX and MPAX series has 4 available setpoint alarm output plug-in

cards. Only one of these cards can be installed at a time. (Logic state of the

outputs can be reversed in the programming.) These plug-in cards include:
