The illustration below shows several items. Some of these are not used in
the A
X
M application and are identified as such. The following describes the
ones that are used.
• Sys Fail—(Red indicator) Comes on at power on and turns off after
internal test routines complete successfully.
• Boot/Run—(Green indicator) Blinks during the boot process and turns
on (steady) when the boot is completed.
• SCSI—It is the interface used for connecting the coprocessor SCSI
(disk drive) interface to the disk drive tray through a cable.
• AUI/VID-A—Provides the interface to the Plant Information Network
(PIN). The PIN is Honeywell’s terminology for the Local Area
Network (LAN).
• RS-232-A—Commonly referred to as Serial Port 1. It provides the
interface for the coprocessor console (terminal) or TAC access modem.
