Installing the Serial Interface

Caution! Handle the interface board with care to avoid damaging its components. The components can also be damaged by static discharges. We recommend that you leave the board in its protective packaging until you’ve read these instructions and are ready to install it. Make sure the printer is unplugged before you install the board.
