2.7.2Using a PC Onsite

Procedures !20 to !25 explain how to use a PC onsite.

!20 To connect a null-modem cable

1.Power off the Multi-Media unit.

2.Connect the 9-pin (or 25-pin) female connector of a null modem cable to one of the PC’s serial ports. Connect the other 9-pin female connector to the RS-232 Port 2 connector at the back of the unit.

!21 To setup a terminal program

1.On the PC connected to a Multi-Media unit, start a terminal session. You can use a program such as HyperTerminal—bundled with Microsoft Windows. The commands for launching HyperTerminal are listed in table 6. The terminal session is used to send commands to the Multi-Media Shell software on the unit. A dialog appears, similar to the Connection Description in figure 18.
