1.3.1 Board Descriptions

SBC/Alarm Transition Board
The Single Board Computer (SBC)/Alarm Transition board must be installed in the
bottom slot (Slot 5) of the card file (see Figure 1-1). This single board computer
contains on-board DRAM, a programmable timer/counter, system interrupt handling
and status monitoring. It also includes a VMEbus interface, SCSI bus interface and
an Ethernet interface.
A McIAS 1610/68 SBC board allows the installation of one McIAS AppSOFT Module;
a McIAS 1610/IP board (SBC-187 or SBC-197) allows the installation of multiple
McIAS AppSOFT Modules. The McIAS 1610/68 and McIAS 1610/IP SBC boards
currently available are described below.
The McIAS 1610/68 SBC board has four LEDs on the front panel: FAIL, STAT,
!
RUN, and SCON.
The McIAS 1610/IP SBC board (SBC-187 or SBC-197) contains the FAIL, RUN,
!
SCON, LAN, SCSI and VME indicators. The SBC-187 also contains a STAT and
+12V (LAN power) LED.
The LEDs on all SBC board types will light at system power-up. Major and minor
alarm LEDs are provided on the front panel of the system.
All SBC board types have two switches. The black ABORT switch is a processor
switch and should not be pressed. The red RESET switch is a "panic button" that
should not be used during normal system operation. If necessary, the RESET switch
may be used to re-start the system.
