Use shielded cable approx. 6 feet in length and for the HD62 use a metalized plastic covers. Ensure the shielding is soldered to the metal of the connectors (HD62 and DB25).

Label each cable near the V.35 connectors as follows:

P2 - Link 0

P3 - Link 1

P4 - Link 2

P5 - Link 3

Rx=Receive, Tx=Transmit, CTS=Clear to Send, RTS=Ready to Send,
DTR=Data Terminal Ready, DSR=Data Set Ready, DCD=Data Carrier Detect
