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.
