Hi guys,

I have three TEF20 units; TEF20SHIP, TEF20LM, and TEF20 REV A.  The first unit communicates using a parallel-hi to parallel cable, parallel-hi to USB adapter, and parallel 25 to parallel 9 cable.  The second two units communicate as well, but they do not communicate using the parallel-hi to parallel cable.

The problem is I will only have parallel-hi to parallel cables to use with these units.  What do I need to do to get them to work?  I have the LPT1 settings as 57600 baud rate, LPT port address as 0x378 (which corresponds to the settings for the port on my computer), neither box is checked ("Force LPT standard" or "bi-directional) as checking them doesn't seem to do anything, and for reference the HI card address is set to 308 which is the default according to the techron book (but no, I don't have one of these old cards since I'm using 6 or 7 year old windows xp laptop).

I'm not sure how active this forum is, but any help would be appreciated.  The switches are set to 5 and 6 down, others up.  I am curious as well if anybody can explain why switch one was down when I got this unit (what does that switch do??), or what the other switches are for, besides the fact 7 and 8 are used to reprogram the unit which I've already managed to perform.

Thanks,

I talked to Louis at gold line and apparently the parallel-hi to parallel cable only works with the newest TEF20 models, since only the newer models switch to RS232 communication when the cable is plugged in.  The older models still need the HI card unless we use a TEFUSB adapter.

Another thing I talked about was that the first switch on the 8 pin SW1 was flipped on these older units, and he believes this switch is a "don't care" which explains why nothing would occur when I flipped it.

Anyways, that confirms all three units work great which is what I was after.
