X.21 and V.35 Cable Pinouts for EIA-530 PIC

The EIA-530 PIC accepts X.21 and V.35 cable connectors.

A V.35connection requires an DB-25 to V.35 cable and connectsto a V.35

data terminal equipment (DTE) 34-pin Winchester type male cable (one per

port). Table 34 describes the V.35 cable pinouts.

An X.21 connection requiresan DB-25 to X.21 cable and connects to a X.21

DTE DB-15 male cable. Table35 describes the X. 21cable pinouts.
