If you are making your own cable, only a few of the cutter pins will actually need to be
connected to the host computer. To ensure optimum results, the cable length should
not exceed 4.8 m (16 feet). It should be taken into account that your computer or
cutting software may also require additional loopback connections at the host
computer's end of the data cable.
• Connect the Transmit Data (TXD) pin of the computer to pin #2 of the cutter.
• Connect the Receive Data (RXD) pin of the computer to pin #3 of the cutter.
• For hardware handshaking, connect the Clear To Send (CTS) pin of the
computer to pin #4 or pin #7 of the cutter. Connect the Request To Send (RTS)
pin of the computer to pin #8 of the cutter.
• Connect the ground (GND) pin of the computer to pin #5 of the cutter.
