The BAUD parameter allows the user to select the baud rate for communica-
tions on this port. The user may choose between 1200, 2400, 4800, 9600,
19200, 38400, and 57600. The default baud rate is 9600.
The LF parameter allows the user to specify whether a linefeed character
(ASCII 0A hex or 10 decimal) is appended to the end of each line transmitted
over the serial port. Selecting ON sends both a carriage return (ASCII 0A hex
or 13 decimal) and a linefeed. Selecting OFF sends only a carriage return.
The ECHO parameter allows the user to set the echo (duplex) mode. Selecting
ON enables echoing so that all characters received on the serial port are echoed
back over the serial port. Echo mode ON is useful when using terminal emula-
tion software on a computer to communicate with the instrument. Selecting
OFF disables echoing. Echo mode OFF is commonly used when using control
software on the computer.
The SER PER parameter allows the user to select the interval at which mea-
surements are automatically transmitted over the serial port. The user may
choose between 1, 2, 5, 10, 15, and 30 seconds, 1, 2, 5, 10, 15, 20, and 30 min-
utes, and 1 hour.
The PRINT parameter allows the user to enable automatic printing of measure-
ments over the serial port. Selecting ON enables printing and selecting OFF
disables printing.
