2.2.2 Command Port - KBU 64 Rear Interface Cards
The command port on each of the Rear Interface Card types is a female 15 way 'D' type and uses the same V28 level circuits as the standalone KBU 64. You can only use this command port when a Manager Card is not fitted into the rack (please see section 3).
The pin assignments are as follows:
Pin No. | Circuit No. | Signal Name |

2 | 103 | Transmit Data |
3 | 108 | Data Terminal Ready |
4 | 104 | Receive Data |

A standard cable (CAB0032) can be supplied to present a standard 25 way interface to the command terminal or PC. This cable has male connectors at both ends.
