AM-314 in any slot for compatibility with your previous configuration. See Chapter 3 of the

Eagle 250 Installation and Technical Manual for more serial I/O configuration information.

If you purchased the optional AM-90 Lightning boards for the eight on-board serial I/O ports,

install them into each of the two bottom rear panel I/O slots (see Figure 7-7). Attach the cable

from the board for ports 0-3 at P1 on the AM-138-10; attach the cable from ports 4-7 at P2.

If you are using DB-9 connectors for the eight on-board serial ports, use the same cables you

used to connect the initial eight serial I/O ports on-your Eagle 200 or 300 to route the on-board

serial ports to the back panel. Use the dual DB-9 connector adapter plates to mount the DB-9

connectors to the back panel. If you choose this option, you’ll need the bottom four back panel

slots, instead of two, for the eight on-board ports.

Install cabling from any other serial I/O boards to the back panel, following the installation

instructions for the I/O board. If you’re using AM-90 cards for the back panel connections

(which we recommend), insert the bottom AM-90s first and work your way up the back panel.

Make sure pin-1 orientation is correct for all cable connections.

If you have a brace for the serial I/O boards (DWB-20791-00 or -01), install it following the

instructions in PDI-20791-00.

Attach the front panel display cable. If it’s a 26-pin connector, use P9; a 20-pin connector plugs

in at P10.

If you use the 20-pin connector, you should also have four wire pairs which were connected to

the front panel from the AM-319. Attach these to the P8 connector on the AM-138-10, as

follows:

Board Label Wires Purpose/Notes

Run Yellow/White Run light; white wire goes toward

edge of board.*

Disk Red/White Disk activity light; white wire toward

edge.*

Power Green/White Power light; white wire toward edge*

Reset Green/Black Reset switch

*: If the light does not work in this orientation, reverse the wires.
