9. Connect an Ethernet cable as follows:
• On QT models, connect an Ethernet cable from ETH2 on the A4I #1 board to ETH2 on the A4B
board.
• On ST and N4 models, connect an Ethernet cable from ETH2 on the A4I board to ETH3 on the
A4M board.
• On SA models, complete the following steps:
a. Disconnect the Ethernet cable between ETH3 on the A4M board and ETH1 on the A4B board.
b. Connect the Ethernet cable from ETH2 on the A4I board to ETH3 on the A4M board.
c. Reconnect the Ethernet cable from ETH1 on the A4B board to ETH1 on the A4I board.
10. If your kit includes a second A4I board, complete the following steps:
a. Install four 1.5-inch hex standoffs to secure the A4I #1 board to the A4M board and provide space
between the two A4I boards.
b. On the A4I #1 board, connect of the second Ethernet cable to ETH1. (You’ll connect the other end
later.)
c. On the second A4I board, ensure that DIP switch S1-2 is ON to designate it as A4I #2.
d. Align the 1.5-inch standoffs with the A4I #2 board. The Ethernet jacks on the A4I #2 board should
be near the Ethernet jacks on the A4M board.
11. Attach the A4I board polycarbonate shield using the supplied screws to secure the A4I #2 board to the
assembly and protect it.
12. If you installed an A4I #2 board, connect the Ethernet cable from ETH2 on the A4I #2 board to ETH1
on the A4I #1 board.
13. Install ground wires for the installed A4I boards using the captive mounting fastener nearest to TBE1
on the A4M board.
Due to the risk of cross-threading standoff, remove the captive mounting fastener by hand.
