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.
ABBREVIATED PRINTING
Select
for full print or Command T transmissions (meter address,
parameter data and mnemonics) or
for abbreviated print transmissions
(parameter data only). This will affect all the parameters selected in the print
options. (If the meter address is 00, it will not be sent during a full transmission.)
PRINT OPTIONS
- Enters the sub-menu to select the meter parameters to appear during a
print request. For each parameter in the sub-menu, select
for that parameter
information to be sent during a print request or
for that parameter information
not to be sent. A print request is sometimes referred to as a block print because
more than one parameter's information (meter address, parameter data and
mnemonics) can be sent to a printer or computer as a block.

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 ADDRESS
Enter the serial meter (node) address. With a single unit, 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.

Module 7 is the programming module for the Serial Communications
Parameters. These parameters are used to match the serial settings of the meter
with those of the host computer or other serial device, such as a terminal or
printer. This programming module can only be accessed if an RS232 or RS485
Serial Communications card is installed.
This section also includes an explanation of the commands and formatting
required for communicating with the PAXDR. In order to establish serial
communications, the user must have host software that can send and receive
ASCII characters. For serial hardware and wiring details, refer to section 4.5
Serial Communication Wiring.
This section replaces the bulletin shipped with the RS232 and RS485 serial
communications plug-in cards. Discard the separate bulletin when using those
serial plug-in cards with the PAXDR. Also, this section does NOT apply to the
DeviceNet, Modbus, or Profibus-DP communication cards. For details on the
operation of the Fieldbus cards, refer to the bulletin shipped with each card.
