The following notes apply to the single X.21 cable:
1. Wires of pair 4 connect to wires of pair 5, but not to any pins in the DA-15.
2. The term "no conn" means the wire is not connected to a pin in the 15-pin connector.
3. Wires 13B and 14B connect to pin 8 in the 15-pin connector.
4. At each end, the cable shield and connector shell must connect to pin 1 of the connector.
5. Do not interconnect Shield to Signal Ground because these are separate signals.
