TLA7xxx hacks (32M Depth on TLA7AA4CS enabled successful) :)

@ bench_knob, KK, dxl, et al,

I'll give this a go on my TLA7AA s this weekend. One of them has max speed, but small depth, the other has max depth, low speed ::). However, I have one two question(s) about the procedure; where you have

      Set Parameters
      Code:
and
      Save Parameters
      Code:

what is the parameter? Is it a drop-down box with pre-defined values, or ...???

When you entered 1404025200 as the timestamp, did you have the true (e.g. today's) date set on the TLA, or had you changed the TLA Windows date to, or near to, 6/29/2014?

Thanks,
Sailor

Yeah, I have this thread marked for when I can find some free time to do the same with one of my TLA704's (I have two).  I wasn't even aware it was possible to use the 7AA4 modules with it, before I read it here.   :-+  Very good stuff, and thanks to all.

As far as I can tell these lines in the lists of commands to sent to the analyzer module were originally intended to be comments on what the following commands were doing and are not actually intended to be sent as commands to the analyzer module:

Set Parameters
Code:

Save Parameters:
Code:

So the literal list of example commands to be sent to the analyzer module would be reduced to the following, where the firmware version in the password string, the sample depth, and the speed would have to match the analyzer module as appropriate:

SYST:PASS:INST:PASS "PitBull5.5.001"
SYST:CONF:DEPTH 4194304
SYST:CONF:SPEED 200
SYST:PASS:INST:UPD 1404025200

I had success in getting these commands to work with a TLA7N4 analyzer module, but the settings did not persist across a power cycle. I believe this might be due to a dead battery in the DS1225AD NV-SRAM in the TLA7N4. I will have to try replacing the DS1225AD NV-SRAM and see if the settings then persist across a power cycle.

One other note, I wasn't able to figure out how to get TekVISA installed on my TLA714 running Windows 2000 SP4 and V4.4 of the analyzer application so I could send the commands to the TAL7N4 module from the TAL714 analyzer mainframe. Instead I installed the TLA7N4 analyzer module in another VXI mainframe with an NI VXI-1394 controller and installed NI-VXI 3.5.2 software on a Window XP system with a 1394 controller connected to the VXI-1394 controller. Then I used the NI-VXI 3.5.2 software to send the commands to the TLA7N4 analyzer module through the VXI-1394 controller. I wasn't sure if I would be able to get that configuration to work together but gave it a try and got it working.

   Ummm ???  So, no selection list, ...?

Congratulations, It sounds like an interesting journey :-+

Correct. That text is just commenting on what the commands are doing are not actual commands to be sent to the analyzer module.

Here are the actual commands that I used to update a TLA7N4 with Option 3S  (100MHz State, 4M Depth) to Option 7S (200MHz State, 4M Depth). Unlike the first TLA7N4 module I tried this one appears to have a working NV-SRAM chip and the option update persists across power cycles.

(write) and (read) are not included the command and response text sent to and from the analyzer module. I used a unix timestamp of 1424217600 corresponding to 02/18/2015 @ 12:00am (UTC). I don't know if that timestamp is used for anything anywhere.
