The following notes apply to the single V.35 DTE cable:

1.The term “no conn” means the wire is not connected to a pin in the 34-pin connector.

2.Wires 12B, 13A, and 14B connect to pin B in the 34-pin connector.

3.At each end, the cable shield and connector shell must connect respectively to pin A of the 34-pin connector and pin 1 of the standard 28-pin connector.

4.Do not connect Shield to Signal Ground because these are separate signals.
