Figure D-12 RS530 to RS449 Conversion Cable
The connecting cable must be a shielded cable.
Circuits which are paired (contain an (A) and (B) reference) should be connected to
twisted pairs within the connecting cable.
This cable is used to connect an RS530 link to an RS449 device. The cable converts from
a DB25 connector to a DB37 connector.
