Chapter 7, IBASIC Controller
Serial I/O from IBASIC Programs
Serial I/O from IBASIC Programs
There are two serial ports available for I/O (input / output) to peripherals external
to the Test Set. To bring data in to the Test Set through the serial port(s) use the
IBASIC ENTER command. To send data out, use the OUTPUT command.
Serial Ports 9 and 10
The Test Set uses a small RJ-11 female connector on the rear panel for connecting
to the two serial ports. This connector has six wires, 3 for Serial Port Address 9
and 3 for Serial Port Address 10. For information about serial port configuration,
refer to the
“Test Set Serial Port Configuration” on page 360. For connection
information, refer to
Figure 26 on page 364.
Before using either port, the RS-232 protocol must be established by setting baud
rate, pacing, and the other settings as explained in
“Test Set Serial Port
Configuration” on page 360
. Functionally, from an I/O perspective, the two serial
ports are identical. However, operationally there is one major difference. The
Serial Port Address 9 settings are adjustable on the I/O CONFIGURE screen or
with IBASIC commands, while the Serial Port 10 settings are adjustable only with
IBASIC commands. There is no screen for Serial Port 10 settings. For more
information, see
Chapter 4, “GPIB Commands,” which gives the command syntax
for Serial Port 9 and 10.
