31 | * Building an adaptor to DE9 / DB25 RS232 | |
32 | * ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ | |
33 | * | |
34 | * DISCLAIMER: Use this description AT YOUR OWN RISK! I'll not pay for | |
35 | * anything if you break your mouse, your computer or whatever! | |
36 | * | |
37 | * In theory, this mouse is a simple RS232 device. In practice, it has got | |
38 | * a quite uncommon plug and the requirement to additionally get a power | |
39 | * supply at +5V and -12V. | |
40 | * | |
41 | * If you look at the socket/jack (_not_ at the plug), we use this pin | |
42 | * numbering: | |
43 | * _______ | |
44 | * / 7 6 5 \ | |
45 | * | 4 --- 3 | | |
46 | * \ 2 1 / | |
47 | * ------- | |
48 | * | |
49 | * DEC socket DE9 DB25 Note | |
50 | * 1 (GND) 5 7 - | |
51 | * 2 (RxD) 2 3 - | |
52 | * 3 (TxD) 3 2 - | |
53 | * 4 (-12V) - - Somewhere from the PSU. At ATX, it's | |
54 | * the thin blue wire at pin 12 of the | |
55 | * ATX power connector. Only required for | |
56 | * VSXXX-AA/-GA mice. | |
57 | * 5 (+5V) - - PSU (red wires of ATX power connector | |
58 | * on pin 4, 6, 19 or 20) or HDD power | |
59 | * connector (also red wire). | |
60 | * 6 (+12V) - - HDD power connector, yellow wire. Only | |
61 | * required for VSXXX-AB digitizer. | |
62 | * 7 (dev. avail.) - - The mouse shorts this one to pin 1. | |
63 | * This way, the host computer can detect | |
64 | * the mouse. To use it with the adaptor, | |
65 | * simply don't connect this pin. | |
66 | * | |
67 | * So to get a working adaptor, you need to connect the mouse with three | |
68 | * wires to a RS232 port and two or three additional wires for +5V, +12V and | |
69 | * -12V to the PSU. | |
70 | * | |
71 | * Flow specification for the link is 4800, 8o1. | |
72 | * | |
73 | * The mice and tablet are described in "VCB02 Video Subsystem - Technical | |
74 | * Manual", DEC EK-104AA-TM-001. You'll find it at MANX, a search engine | |
75 | * specific for DEC documentation. Try | |
76 | * http://www.vt100.net/manx/details?pn=EK-104AA-TM-001;id=21;cp=1 | |
