Pin
Indicator
Specifies whether the termination resistance is connected for the Host Link System. Turn this pin ON to
connect the terminal resistance. When RS-422 is used set this pin to ON at the last PC connected in the Host
Link System. When RS-232C is used, this pin does not affect Host Link System operation and may be set to
either ON or OFF.
To transfer the user program file (AUTOEXEC.OBJ) and the PC Setup (AUTOEXEC.STD) from the Memory
Card to the CPU on power application, set this pin to ON. If this pin is set to OFF, the PC Setup can be
changed from the CVSS so that only the user program (AUTOEXEC.OBJ) is transferred when power is
turned on. If program transfer is designated both with this pin setting and in the PC Setup, then both the
program file and the PC Setup will be transferred. The user program will not be transferred when the system
protect keyswitch on the front panel of the CPU is set to the SYSTEM PROTECT position, or memory is
write-protected from the CVSS.
Set this pin to the ON position to establish the following communications settings for the host link interface.
These are the most common setting for an IBM PC/AT interface.
Baud rate:
Unit number: 0
Parity:
Data length: 7 bits
Stop bits:
When this pin is OFF, the communications settings for the host link interface are set in the PC Setup. Refer to
the CVSS Operation Manuals for details on the PC Setup.
Note: The above settings apply to CPUs manufactured from July 1995 (lot number **75 for July 1995). For
CPUs manufactured before July 1995 (lot number **65 for June 1995), only 1 stop bit will be set and the
baud rate will be 2,400 bps.
Lights when power is supplied to the CPU.
Lights when the PC is operating normally.
Lights when an error in the CPU causes operation to stop. When the ERROR indicator lights, the
RUN indicator will go out and all outputs from Output Units will be turned OFF.
Lights when a CPU error (watchdog timer error) has been detected. When the WDT indicator
lights, the RUN indicator will go out and all outputs from Output Units will be turned OFF.
Lights when non-fatal error is detected.
Lights when the Output OFF Bit (A00015) is turned ON to turn OFF PC outputs.
Lit from when data is received from the host computer until the response is completed.

The following table describes the indicators on the front panel of the CPU.
The DIP switch is used to set certain basic operational parameters for the CPU.
To gain access to the DIP switches, open the cover of the Memory Card com-
partment as shown in the following figure. Turn off power to the PC before setting
the DIP switch.
