Jim,
I don't know if your message is in response to those I have sent =
regarding my experience building a 301, or if you have received any =
other responses, but.....
Contact Ten-Tec Service Department (423-453-7172) and ask for whatever =
parts they have that comprise the 301. It may, depending on what parts =
they have remaining cost about 60 dollars. As to documentation, you =
don't need any. The parts list is amazing light.
Here is a summary parts list of needed items:=20
1. rotary optical encoder
2. case
3. weight
4. knob (I ordered an Omni VI knob separately after I got the unit =
wired up and working)
The rest (screws, strain relief, cable, terminal strip) , you can =
acquire locally at a Radio Shack or whatever.
The wiring is straightforward.
Four of the five pins of the rotary encoder are marked to indicate =
function:=20
1. Minus sign
2. blank
3. A
4. Plus sign
5. B
This is how I hooked my 301 up using a DB25M connector:=20
Minus to Pins 1, 14, and 7 (ground)
A to Pin 6 (phase 1)
Plus to Pin 16 (+5V)
B to Pin 8 (phase 2)
I used a shielded, 4 conductor cable about 5 feet long to run from the =
back of the Omni VI, under the desk, and to the 301 on an =
under-the-desktop-keyboard drawer shelf attachment I made, and it works =
perfectly. =20
That should do it. =20
At the minimum, the rotary optical encoder is the heart of the 301. If =
Ten-Tec no longer has anything else, they will have the encoder. You =
can find any box (I recommend the sloped front type) to put it in. =20
73 and HNY,
