Page 131: Remote Control Applications
External Controllers and Printers Remote Control Applications The ST112 SONET Transmission Test Set can be remotely operated from its RS-232-C, ST112, or GPIB ports in one of the following ways: • Use the RS-232-C Port manually from a VT100 terminal or VT100 emulation program, using the ST112 SONET Transmission Test Set Virtual Front Panel feature.
Page 132: Using The Rs-232C Port
The RS-232-C interface is a 9-pin D-type socket connector located on the rear-panel. The pin-out of this connector is shown in Table 6–2 below. The ST112 SONET Transmission Test Set RS- 232-C port is wired as a DCE (data communications equipment) device, it receives on pin 2 and transmits on pin 3.
Page 133 Chapter 1, Getting Started. Quick Test, RS-232-C Port You can perform a quick test of the ST112 SONET Transmission Test Set RS-232-C port using a terminal (or a PC running terminal emulation software) as follows: 1. Verify that the Test Set echo mode is on.
Page 134 GPIB port. Error Messages The ST112 SONET Transmission Test Set verifies all commands received on the RS-232-C port to make sure that they contain the appropriate mnemonics and parameters. All valid commands will be executed.
Page 135 ------------------------------------------------------------------------- Figure 6–1 Error Reports Available (Example Screen) Be sure that the ST112 SONET Transmission Test Set printer function is turned off before activating the VT100 emulator. The printer and VT100 cannot work simultaneously through the single Test Set RS-232 port. If a parallel printer is connected to the ST112 SONET Transmission Test Set parallel printer port, then the printer and VT100 remote screen can function simultaneously.

Remote Commands Command Types and Syntax The ST112 SONET Transmission Test Set command set includes two basic types, set and query. The set commands are used to change current status, values, or states—to start or stop a test, for example. While query commands ask the instrument to respond with the contents of a status register, the value of a given setup parameter, a measurement result, or a current state.
