4.Select the DB9 and DB25 cutouts you want to use on your Eagle
computer’s rear panel. Remove the knock-out covers from the selected
cutouts. Install the free end of the DWB-10314-00 cable to the rear panel
using the hex-nut screws included in the installation kit.
The DB9 connector has threaded PEM-nuts, which the hex-nuts thread
into. The DB25 connector requires two #4 nuts that are used in conjunction
with the hex-nuts. All necessary hardware is included.
5.Now, install the DWB-10154-00 cable that links the AM-338 board’s J1
connector to the AM-339 board’s J1 connector. Make sure the cable is
installed pin-1 to pin-1. Figure 1 shows the pin-1 location for the AM-338
and AM-339 boards.
6.After the hardware has been installed, 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 configuration is running properly.
A simple diagnostic to verify the operation of the AM-339 board is to use
an an oscilloscope to watch the DTR line (pin 20 on the DB-25 connector).
After a reset, DTR will go low for around two seconds while the AM-339
performs a memory self test. After memory self test has completed, DTR
will go high.
7.Once self test has passed, power the computer down again, replace the
top cover, and proceed to the next section.
