Installation manual

Diagnostic Engineering Monitor
The Diagnostic Engineering Monitor (DEMON) is entered when the Diag/Norm switch is in the Diag
position.
POSITION SYSTEM ACTIVITY
DIAG Enters DEMON mode when Self-test is completed.
Self-test output is monitored by connecting the ISP-80 controller to a terminal set to 9600 baud, 8 data
bits, no parity, and 1 stop bit. The ISP-80 Controller serial port is a 25-pin, dual in-line, header-type
connector.
Since Sun does not make a cable that connects the ISP-80 controller and a terminal, use an adapter
cable and a null modem cable.
Adapter Cable
Examples of Sun cables that can be used as adapter cables are:
530-1178-01 (ALM-1, RS-232)
530-1179-01 (ALM-1, RS-232)
530-1312-02 (ALM-2, Printer)
530-1313-01 (MCP, RS-232)
Sun SMD data cables cannot be used as the adapter cable because they do not have Pin 2.
Null Modem Cable
The null modem cable must have Pins 2 and 3 crossed and Pin-7 straight. Laserwriter Cable
530-1172-03 is an example of this type of cable.
