RS-232 C
ONTROL
The SuperView has two RS-232 serial communications ports for remote control
of its functions, enabling the SuperView to receive data and instructions from
host applications, and to be explicitly controlled with commands sent via the
serial port from a computer (or ASCII terminal). This port is configured
according to the Electronic Industries Association Standard RS-232-C
published in August 1969.

Physically, the RS-232 ports are 9-pin D-Sub female connector.

The SuperView can be explicitly controlled with ASCII Command Set
instructions sent via the Primary RS-232 serial port from either a computer or
an ASCII terminal. See Chapter 6 for details of the Command Set.

an ASCII terminal. See Chapter 6 for details of the Command Set.
The Auxiliary serial communications port is provided to implement daisy-
chaining of multiple systems. The Auxiliary port of an upstream unit is
connected to the Primary port of a downstream unit (Figure 11). When a unit is
not selected, it passes all commands to its downstream port, and passes all
responses from its Auxiliary port back to the console. See Appendix D, “Serial
Control of Multiple Units.”

Serial Control of Two SuperViews
Determine whether the computer’s serial port has a 9-pin D-Sub or 25-pin D-
Sub connector. Use a 9-pin to 9-pin serial cable to connect the SuperView’s
serial port to that of the computer (with a 9-pin to 25-pin adapter to complete
the connection if necessary).

When controlled from an ASCII terminal, the SuperView must echo characters
as they are typed—this enables you to see characters as you enter them.
However, if you are using a serial port on a UNIX workstation, the “echo”
option must be disabled to ensure correct operation. Selection of “echo” or “no
