5.5.1 Setting Up the RS-232 Interface
The baud rate is set from the front panel by SETUP-MORE-COMM-BAUD. Select the baud rate
appropriate for your application, 300, 1200, 2400, 4800, 9600, or 19,200. It is important to note
that the other device must have identical settings in order for the communications to work
correctly.
Second is physical wiring of the analyzer to the other unit. We have incorporated into the
Analyzer LED's that signal the presence of data on the communications lines, and also switches
to easily re-configure the analyzer from DCE to DTE if necessary. In addition the front panel
diagnostics allow test data streams to be sent out of the port on command. This flexibility and
diagnostic capability should simplify attaching our equipment to other computers or printers. If
problems occur, see the Troubleshooting Section 9.3.2.
Setup from the Front Panel
There are 2 additional RS-232 setups that can be done via the front panel.
1. Set the instrument ID number by SETUP-MORE-COMM-ID, and enter a 4 digit number
from 0000-9999. This ID number is part of every message transmitted from the port.
2. Set the RS-232 mode bit field in the VARS menu. To get to the variable press, SETUP-
MORE-VARS, then ENTR and scroll to RS232_MODE, then press EDIT. The possible
values are:
5-24
