Fluke 1522 - Manual (Page 49)

The protocol for serial communications is 8 data bits, 1 stop bit, and no parity.
Use no flow control. The baud rate is fixed at 2400, the linefeed to ON (all car-
riage returns are followed by a linefeed (ASCII decimal 10)), and the duplex to
HALF disabling echo.
The serial port can be used to transmit measurements to a computer or printer.
It can also be used to change settings of the instrument from a computer or in-
terface with software. A full list of commands follows in Section 8.2.
Commands sent to the instrument must end with an EOS character which is a
carriage return (ASCII decimal 13) or linefeed character (ASCII decimal 10).
Commands can be sent with upper or lower case letters. Data returned from the
instrument ends with a carriage return and a linefeed.
