6.7 MODULE 7 - S ERIAL C OMMUNICATIONS P ARAMETERS ( ????? )
PAXI O NLY
PARAMETER MENU
Module 7 is the programming module for the Serial Communications
METER UNIT ADDRESS
Parameters. These parameters are used to match the serial settings of the PAXI
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 PAXI. In order to establish serial
communications, the user must have host software that can send and receive
ASCII characters. Red Lion's SFPAX software can be used for configuring the
PAXI (See Ordering Information). For serial hardware and wiring details, refer
to section 4.5 Serial Communication Wiring.
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.
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 PAXI. 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.
BAUD RATE
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.)

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.

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 information (meter address, parameter data and
mnemonics) can be sent to a printer or computer as a block.
Select either 7 or 8 bit data word lengths. Set the word length to match the
other serial communications equipment on the serial link.

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.
