BAUD RATE

Set the baud rate to match the other serial communications equipment on the

serial link. Normally, the baud rate is set to the highest value that all the serial

equipment are capable of transmitting and receiving.

DATA BIT

Select either 7 or 8 bit data word lengths. Set the word length to match the

other serial communications equipment on the serial link.

PARITY BIT

Set the parity bit to match that of the other serial communications equipment

on the serial link. The meter ignores the parity when receiving data and sets the

parity bit for outgoing data. If no parity is selected with 7 bit word length, an

additional stop bit is used to force the frame size to 10 bits.

METER UNIT ADDRESS

Enter the serial meter (node) address. The address range is dependent on the



parameter. With a single unit, configured for RLC protocol ( =



), an address is not needed and a value of zero can be used. With multiple

units (RS485 applications), a unique 2 digit address number must be assigned

to each meter.

to  (Modbus)

Select the desired communications protocol. Modbus is preferred as it

provides access to all meter values and parameters. Since the Modbus protocol

is included within the PAXDP, the PAX Modbus option card, PAXCDC4,

should not be used. The PAXCDC1 (RS485), or PAXCDC2 (RS232) card

should be used instead.

SETPOINT ANNUNCIATORS









The  mode disables display setpoint annunciators. The  mode

displays the corresponding setpoint annunciators of “on” alarm outputs. The



mode displays the corresponding setpoint annunciators of “off” alarms

outputs. The  mode flashes the corresponding setpoint annunciators of

“on” alarm outputs.

Alternate Setpoints

An Alternate list of setpoint values can be stored and recalled as needed. The

Alternate list allows an additional set of setpoint values. (The setpoint numbers

nor rear terminal numbers will change in the Alternate list.) The Alternate list

can only be activated through a function key or user input programmed for 

in Module 2. When the Alternate list is selected, the Main list is stored and

becomes inactive. When changing between Main and Alternate, the alarm state

of Auto Reset Action alarms will always follow their new value. Latched “on”

alarms will always stay latched during the transition and can only be reset with

a user input or function key. Only during the function key or user input

transition does the display indicate which list is being used.

- A communication card must be installed in order to access this

module.

Setpoint Alarm Reset Actions

When , the alarm is disabled (after a power up) until the trigger point is

crossed. Once the alarm is on, the alarm operates normally per the Setpoint

Action and Reset Mode.
