New PE43703 - HELP!

[M0LIH]

Good Afternoon,

I have purchased a PE43703 to go with a Portsdown Setup for QO-100.

I think I have a slightly newer model / different layout than in the instructions on the wiki site.

Before I blow something up, please could someone have a look at this with me and explain what I need to do to it before using it?
The main confusion come from the fact that it doesn't have the solder pads as described in the Output Attenuator instructions.
I think that it could be on the jumpers on the right hand side, but wanted to check before I proceed.

Please see picture below;


Many thanks in advance an 73 to all!

Please could you try to post a higher resolution picture? Not enough detail here to be confident of any advice.

Hi Ian

The full res image from flickr was perfect. The forum simply takes what is uploaded to it, but does have an upper limit on file size.

You need to make sure that the P/S DIP switch (the left-most one) is in the off position (down) so that the P/S line is high. The other DIP switches are then irrelevant.

Then the following connections to the header:

Code: Select all

A0 - Gnd
Data - SPI Data
Clk - SPI Clock
LE - Atten LE
A1 - Gnd
3v3 - NC as the supply comes from the 5v connector on the left of the board
Gnd - Gnd
A3 - Gnd
P/S - NC

(and take off that shorting jumper)

It is important that A0, A1 and A2 are grounded because that is the address (000) that the software addresses it by.
