Configuring the RS-232C Port(s)
2-10 Operating and Programming Guide
Making Changes to the Serial Port Settings
(If Needed)
CAUTION If you change the serial port settings, your changes will be
stored in the Receiver. Cycling power will not reset to factory
defaults. Therefore, if you make a change, it is recommended
that you record the settings and keep the record with the
Receiver.
If you need to change the serial port settings, for example, to set
up for a different computer, use the guidelines given in this
section.
Serial port settings are changed by issuing commands.
It is recommended that you issue a single compound command which
simultaneously sets all the serial port parameters. Then connect the
other computer and begin using the instrument with the new settings.
NOTE If you choose to set parameters one at a time, you will make the
procedure more difficult. That is, with each change, the instrument
will be updated, but your computer will retain its original settings.
At each step, you will have stopped serial communications and be
forced to modify your PC settings to match the Receiver in order to
continue. It is recommended that you make all changes in a single
compound command, verify the changes, and record all parameters.
Configuring PORT 1 of the 59551A
Complete configuration of PORT 1 of the 59551A requires that you set
five parameters. The command line sent in the following example
would set the RS-232C port pacing to XON, baud rate to 2400, parity to
EVEN, data bits to 7, and stop bits to 2. This command line must be
transmitted on PORT 1.
SYST:COMM:SER:PACE XON; BAUD 2400; PARITY EVEN; BITS 7; SBITS 2
Configuring PORT 1 of the 58503B and PORT 2 of the
59551A
Complete configuration of PORT 1 (58503B) and PORT 2 (59551A)
require that you set three parameters. The command line sent in the
following example would set the RS-232C port pacing to XON, baud
rate to 2400, and parity to EVEN. This command line must be
transmitted on PORT 1 or PORT 2.
SYST:COMM:SER2:PACE XON; BAUD 2400; PARITY EVEN
