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.
4.1Step 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.
