Tim & All I'm do not know what the requirements for IEEE 1284 are, all I can do is repeat the manufactures web page. "Compliant with IEEE 1284 - 1994 parallel port standard" "Supports ECP, EPP, PS2 and SPP modes" "Works with various types of parallel devices including printers, removable drives, scanners, CS-R/RW's, and more...."
What I do know comes from trial and error. I am currently using the SIIG board that I mentioned previously. The computer is a clone I build about a year or so ago. It is based on an Intel Dual - Quad core processor. I have it set up as a dual boot system for Win. XP-32 and Win 7 - 64 bit system. I specifically purchased this board because it has 2 serial ports and 1 parallel port. The equipment I am using : F3K LP 100A watt meter (serial com 1) Ameritron ALS-500M amp. (parallel port, 4 BCD pins E ,F ,G & H or 6 ,7 ,8 & 9) Ameritron RSC-12C Antenna Switch (parallel port, 4 BCD A, B, C & D or 2, 3, 4 & 5) Tuner at this time is a manual Palstar. Please note that I am using all 8 BCD data bits. Operational software for Windows 7 - 64 bit. (In order of loading and running) VSP Manager DDUtil 2.0.0.52 PowerSDR 2.0.16 Mini Deluxe DM-780 Operational software for Windows XP - 32 bit. (In order of loading and running) VSP Manager DDUtil 2.0.0.52 PowerSDR 2.0.16 Mini Deluxe DM-780 As much as possible all programs are set up identical - same communications ports etc..... No changes in hardware are made when booting between the two operating system. So the only real difference that I know of is the driver for the parallel port. One is an XP-32 bit driver and one is a Win 7 - 64 driver. Results: When using Win XP - 32 - everything works (antenna switch and amplifier). When using Win 7 -64 - antenna switch and amplifier do not work. Construction : I made the interconnect cables myself. When doing this I first checked for shorts and opens. Then I connected the cable to the parallel port. I then ran the software and checked the switching voltage at the end of the cable. I was surprised to fine 3.35VDC, I had expected to see 5VDC. I can see where this difference may not switch all devices. Anyway for what's it worth, that's what I've done so far.
