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.

NO

PAr

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.

Addr

METER UNIT ADDRESS

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

tYPE

parameter. With a single unit, configured for RLC protocol (

tYPE

=

rLC

), 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
2100 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 2100. In order to establish serial
communications, the user must have host software that can send and receive
ASCII characters or utilizes Modbus protocol. For serial hardware and wiring
details, refer to section 3.6 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 2100. Also, this section does NOT apply to the
DeviceNet, or Profibus-DP communication cards. For details on the operation
of the Fieldbus cards, refer to the bulletin shipped with each card.

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 2100, the

Modbus option card, should not be used

The RS485 or RS232 card should be used instead.

TRANSMIT DELAY

Following a transmit value (‘*’ terminator) or Modbus command, the

2100 will wait this minimum amount of time in seconds before issuing a
serial response.
