Remote Operation

Introduction
Two operating modes—local or remote—control the Analyzer. When the Analyzer is
powered on, it initializes in local mode. The Analyzer keyboard is enabled, and the
Analyzer can understand information input from its front panel.
The remote mode allows communication with the Analyzer, using a serial controller (a
computer with an RS232 port or a medTester with medCheck). Connect the Analyzer to
the controller with a null modem cable. As soon as the Analyzer receives a remote
command from a controller, it goes into the remote mode and recognizes commands from
only that controller.
The Analyzer keyboard is completely disabled during remote operation, except during
some procedures in which the Esc or function keys are needed. To return the Analyzer to
the local mode, use the GOTOLOCAL command. Program examples are given at the
end of this chapter.
There are two types of commands associated with the Analyzer:
• Those that instruct the Analyzer to simply perform a procedure
• Those that cause the Analyzer to perform a procedure and send test results (data)
back to the controlling device.
If the command instructs the Analyzer to do a procedure that generates no data, such as
drawing a pressure envelope, the Analyzer completes the procedure, then sends an
asterisk (*) to the controller. When the asterisk displays, the Analyzer has received,
understood, and carried out a command.
The following sections on remote commands include instructions on writing commands,
an error message list, a section of detailed command descriptions, and examples of how
to use the Analyzer commands in a computer program.
Setting Up the medTester
Before the Analyzer can communicate with a medTester, the medTester must be
configured, using the values listed in Table 3-1.
