Instrument Operation
7. Set Serial Rate
This menu item enables changing the serial rate of the data sent to the
RS-232 port.
1. At Set Serial Rate, press START to display Serial Rate = xxxx.
2. At Serial Rate = xxxx, the serial-port baud rate may be reset by
means of the < or > key to either 1200, 2400, 4800, 9600, or 19200
baud.
3. Press ENTER to store the new setting (or STOP to restore the
original setting).
8. Dis/Enable Xon/Xoff
This menu item enables or disables the Xon/Xoff handshaking protocol
for RS-232 communication.
1. At Dis/Enable Xon/Xoff, press START to display [on] < Xon/Xof *
[off]. The current setting is indicated by the symbol, *.
2. At [on] < Xon/Xof * [off], press < or > to enable or disable serial-
port Xon/Xoff handshaking.
3. Press ENTER to store the new setting (or STOP to restore the
original setting).
Note Sending a CTRL-S from the connected PC will suspend RS-232
output until you send a CTRL-Q. While suspended, data will
accumulate in the UART output buffer. However, output buffer
memory is limited, and data will be lost if the output remains
suspended for too long.
9. Serial Number
1. At Serial Number, press START to display the instrument serial
number (Serial #: 123).
2. Press STOP to return to the setup menu. This number is set by the
factory and cannot be changed by the operator.
