RS-442/449 to RS-530 Adapter Cable
Using an AMT-70 with devices that have an RS-422/RS-449 interface (such as a BER tester)
requires an adapter cable. Although the RS-530 and RS-422/RS-449 interfaces are electrically
identical, they have different connectors.
Use a cable with the pin-outs as listed in the figure below;
