Chapter 3, Operating Overview
Using Remote Control
Using an ASCII Terminal
Connecting an ASCII terminal to the serial port allows you to remotely operate
the Test Set by entering characters that represent each front-panel control.
Before you can use this feature, you must first set the required serial port settings
in the I/O CONFIGURE screen, and make any hardware connections.
The Serial Port connections are described in
chapter 24, "Connector, Key, and
Knob Descriptions"
.
To Configure for Serial Port Operation
1. Access the I/O CONFIGURE screen.
2. Set the
Serial In
field to
Inst
.
3. Set the
IBASIC Echo
field to
On
.
4. Set the
Inst Echo
field to

.
5. Set the remaining serial communications fields according to your terminal/computer’s
serial communication requirements. These fields include:
•
Serial Baud
• Parity
• Data Length
• Stop Length
• Rcv Pace
• Xmt Pace
6. The Test Set now responds to the equivalent characters sent to it by the terminal/com-
puter.
Equivalent Front-Panel Control Characters
Table 6 on page 87
lists the terminal/computer keystrokes that equate to front-
panel controls. Each sequence must be preceded by the Escape key.

press the C key on your terminal/computer. Be sure to use upper-case C for this
example.
