USB SETUP
CNFG SErL
CNFG = Configures USB with settings required to operate
with Crimson configuration software. This will
automatically internally configure the PAX2C USB
port to use Modbus RTU protocol, 38400 baud, 8
bits, and unit address of 247. The serial port settings
in the Serial Parameters (SErL) will not change, or
show this.
SErL = Configures USB to utilize serial settings and
protocol as configured in the Serial Parameters.

COMMUNICATIONS TYPE
ASC = Modbus ASCII
rLC = RLC Protocol (ASCII)
rtu = Modbus RTU
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 PAX2C, the PAX Modbus
option card, PAXCDC4, should not be used. The PAXCDC1 (RS485), or
PAXCDC2 (RS232) card should be used instead.
BAUD RATE
1200 2400 4800 9600 19.2k 38.4k
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
7 8
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 *
NO EUEN Odd
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.
* Available when Data Bit = 7.
