Gordon -- Here's a "conversion table" to help you convert from the Mini-DIN connectors to the DB-9 connectors: DB-9 Pin DIN Pin Description -------- ------- ---------------------------------------------------- 1,3 4 Ground 2 +5V -- see Inside Macintosh for power limits 4 6 TxD+ -- transmit data 5 3 TxD- -- transmit data (TxD+/TxD- may be used to drive a twisted pair) 6 +12V -- see Inside Macintosh for power limits 7 2 Input handshake (CTS or TRxC, depends on Zilog 8530 mode) 8 8 RxD+ -- receive data 9 5 RxD- -- receive data (also a twisted pair) 1 Output handshake (8530 DTR) 7 Not connected Blanks indicate no corresponding connection.
