RS-232 Cable Chart

Locate the actual serial connector on the back of the vendors equipment. Find that connector in the left column below. Check the pin out of Transmit (Tx). Then click on the Destiny Networks cable name under the Domain 3000 column. You will be linked to a drawing of the cable and how it connects to the vendors equipment.

Note that the convention is that DB9 male connectors on the vendor's equipment should use a standard straight through cable, and DB9 female connectors on the vendor's equipment should use a crossover cable.
