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...."
But what you are doing with the parallel port is not sending data to parallel devices. Obviously the x64 drivers are not meeting the manufacturer's claims whereas the x86 drivers are. You have done more than most and your test setup eliminates many variables. Obviously the x64 drivers are not meeting the manufacturer's claims whereas the x86 drivers are. This brings back memories of the transition from 16 to 32-bit Windows. I assume when I am a bit more gray headed, we'll be doing the 64 to 128-bit "dance". Oh what fun. -Tim -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Don Sent: Tuesday, December 28, 2010 6:02 PM To: Flex Edge Subject: [FlexEdge] Parallel Ports Tim & All I'm do not know what the requirements for IEEE 1284 are, all I can do is repeat the manufactures web page.

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.
