It is necessary to match the PAX meter’s serial communications parameters
to the host’s parameters before communications can be established. This is
accomplished by using the PAX front panel keys to enter .

Parameter
Selection/Value
Set the baud rate to match that of other serial communications equipment.
Normally, the baud rate is set to the highest value that all of the serial
communications equipment is capable of transmitting.
Select either 7 or 8 bit data word lengths. Set the word length to match that
of other serial communication equipment. Since the meter receives and
transmits 7-bit ASCII encoded data, 7 bit word length is sufficient to request
and receive data from the meter.
Set the parity bit to match that of the other serial communications equipment
used. 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 the meter
transmits and receives data with 2 stop bits. (For example: 10 bit frame with
mark parity)
Enter the serial node address. With a single unit on a bus, an address is not
needed and a value of zero can be used (RS232 applications). Otherwise, with
multiple bussed units, a unique address number must be assigned to each meter.
The node address applies specifically to RS485 applications.
Select abbreviated transmissions (numeric only) or full field transmission.
When the data from the meter is sent directly to a terminal for display, the extra
characters that are sent identify the nature of the meter parameter displayed. In
this case, select . When the data from the meter goes to a computer, it may be
desirable to suppress the node address and mnemonic when transmitting. In this
case, set this parameter to .
- Enters the sub-menu to select those meter parameters to appear in the
block print. For each parameter in the sub-menu select for the parameter to
appear with the block print, and to disable the parameter.
*Setpoints 1-4 are setpoint plug-in card dependent.
