RS-232 DB-9 to DB-25 Terminal Cables

This section tells you which pins to connect to construct cables for particular terminals supported by
Alpha Micro. We have grouped the signals into pairs which will also allow longer and more reliable
communication to the computer system.

The AM-60, AM-62, and AM-70 terminals are all RS-232 devices and use the same cabling. The AM-
62A, AM-65, AM-72, and AM-75 terminals, when used as RS-232 devices, also use these pinouts.

For RJ-45 connectors, use the standard AM-359-50 cable set or straight RJ-45 patch cords. The
RJ-45 connectors use the same pin-outs as DB-9 connectors.

The following table gives the pinouts required for RS-232 cables connecting a terminal to the computer:

Table A-2: Pinouts for RS-232 Terminal-to-Computer Cables

The DTR connection (pin 20) to the computer (pin 4) can serve as 'READY/NOT BUSY' handshake line
to prevent 'overrunning' the terminal with data. This protocol is also effective for several printers used by
Alpha Micro.

Caution: While this cable configuration enhances the use of the Alpha Micro terminals, it may
degrade system performance with other types of terminals and printers if they do not provide a
compatible DTR on pin 20. In such cases, the connection to pin 4 at the computer end should be
disconnected.
