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.
See Chapter 2 of System Programming.

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