Page 3Installation Instructions: AM-338 / AM-339 RJE Board Set
The AM-366 Ethernet controller must always be installed in connector J14 in the
AM-1600 computer.
If you must remove an AM-314 serial I/O board in order to install the AM-338 board,
remember to remove the TRMDEF and SETJOB statements from your AMOSL.INI file
supporting the serial I/O board you are removing.
4.1Step by Step Installation (AM-1600 Desktop Model)
1.Power down your computer and remove the top cover.
2.Remove all cables connected to the AM-135 CPU board, take note of
where each cable is connected and how it is routed.
3.Completely remove the AM-135 CPU board from the computer. You’ll
need to squeeze the nylon locking posts in order to remove the CPU board
from the computer. Use a hex-driver to remove the hex-screws securing
the parallel printer port to the rear panel.
4.Using a hex-driver, remove all the serial I/O connectors from the rear
panel. Also, remove the SCSI connector from the rear panel using a small
phillips-head screwdriver.
5.Now, remove the rear panel by removing the four phillips-head screws
holding it in place. Replace the old rear panel with the new rear panel
included in the product kit.
6.Connect the serial port connectors to the new rear panel, replace the
hex-screws for the parallel port, and attach the external SCSI connector.
7.Re-install the CPU board and re-connect all cables you removed earlier in
this procedure.
8.Insert the AM-338 board into connector J14. Use J15 only if you have an
AM-366 Ethernet controller board installed in your computer.
9.Screw the AM-339 board into the rear panel using the supplied screws and
connect the ribbon cable between the two boards; being sure to connect
pin-1 on the AM-338 to pin-1 on the AM-339.
10.Power up the computer and run self test. Although self test will not check
the AM-338/AM-339 board set, it will insure that your basic system is
working properly.
