	Types of PC Connections	6

There are three ways to connect the PC to the control unit:

■Direct Local Connection. For a direct local connection, you must connect the PC to the system programming jack (labeled ADMIN). This is the lower modular RS-232 jack on the processor module. (The upper jack is reserved for the SMDR printer.)

■Local Modem Connection. For a local modem connection, you must use a modem (either connected to or built into the PC) to access the internal modem in the control unit. Connect the modem to a 012 or 016 (Release 4.0 and later systems only) module in the control unit.

■Remote Modem Connection (DOS-Based SPM Only). For a remote modem connection, you must use a modem (either connected to or built into the PC) to access the internal modem in the control unit. You must also use a modem to dial into the system using remote access.

NOTE:

Remote access (modem connection) has priority over local access (direct connection), unless a backup or restore procedure is in progress through a direct local connection. If a modem connection is attempted while any other type of on-site programming is in progress (either at the system console or at a directly connected PC), the system sends a message to the on-site programmer. The message indicates that a modem connection is being established, and the on-site programming session is terminated.

Access to System Programming 6

Before you can begin system programming from a PC, you need to access the SPM software. The procedure for reaching SPM depends on whether your PC is connected to the control unit with a modem (either local or remote) or without a modem (direct). This section describes both of these procedures.

With a Direct Local Connection 6

To begin using SPM when your PC is connected directly to the control unit, follow

the steps below. For information about the procedure format, see ‘Using‘ the Programming Procedures’’ on page 6-3.

Console/Display Instructions Additional Information

Set up the proper physical connections between the PC and control unit.

If you installed SPM on the hard disk of the PC, go to Step 5.
