For more information about setting up and using SPM for programming on a PC
with DOS, see Chapter 2 of
System Programming . For information about
accessing SPM from IS II/III, refer to the appropriate book:
■ Integrated Solution System Manager’s Guide
■ Integrated Solution Installation and Maintenance Guide
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 (T/R)
(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 when you are 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 onsite programming is in progress
(either at the system console or at a directly connected PC), the
system sends a message to the onsite programmer. The message
indicates that a modem connection is being established, and the
onsite 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 access procedures.
