................................ .

TheSuperView has two RS-232 serial communications portsfor remote control

ofits functions, enabling the SuperView to receive data and instructions from

hostap plications, and tob eexplici tlyco ntrolled with commands sent via the

serial port from a computer (or ASCII terminal). Th is port is configured

accordingto the Electronic Industries Association Standard RS-232-C

publishedin August 1969.

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

................................................

TheSu perViewcan be explicitly controlled with ASCII Command Set

instructionssent via the Primary RS-232 serial port from either a computer or

anASCII terminal. See Chapter 6 fordetails of the Command Set.

TheAu xiliary serial communications port is provided to implement daisy-

chaining of multiple systems. The Auxiliary por t of an upstream unit is

connectedto the Primary port of a downstream unit (Figure 11). When a unit is

notsel ected,it p asses all commands to its downstream port, and passes all

responses from its Auxiliary port back to the con sole. SeeAppendix D,“Serial

Controlof Multip leU nits.”

FIGURE11. Serial Control of Two SuperViews

Determinewhether the computer’s serial port has a 9-pin D-Sub or 25-pin D-

Subconnector. 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

theconnection if necessary).

When controlledfrom an AS CII terminal, theS uperViewmust echo characters

asthey 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”

optionmust be disabled to ensure correct operation. Selection of “echo” or “no
