I use now:

Code: [Select]

#value V1 V D2
#value V2 V D2
#value V3 V D2
#value V4 V D2
#value A1 A D3
#value A2 A D3
#value A3 A D3
#value A4 A D3
#value Status - DIGITAL(OFF,CV,CC)

#askValues getV? 1;getV? 2;getV? 3;getv? 4;getC? 1;getC? 2;getC? 3;getC? 4;[50];status? 1;[50];status? 2;[50];status? 3;[50];status? 4
#readingdelay 1

The Result (cut):

For using the last Output string the NaN must be a 0,1 or 2 (OFF, CV or CC)
So how can i change the OFF, CV and CC in 0,1 and 2?
I hoped the DIGITAL Parameter do this.

No the digital format show bits as text, but it need a numeric input.
Use:
:readmath: listIndex(value,"OFF CV CC")
To do the conversion from string to number

Next Problem:
#cmdSetup buttonsOn CH-1
:read:
:updatealloff:
Off off
On on

This Buttons works ok, but i dont know which :read: Command i must use for the Red/Green Light?

The result from :read: must match the "on" value, then the indicator will turn on.

The ON value is only for switch the Output on/off:
#scpiCmd on tx ENABLE
#scpiCmd off tx DISABLE
I can not read this parameter in the PS.

The only way is to read out the status?
When Answer is "OFF" then output is off.
When Answer is "CC" or "CV" then Output is on.
But i am not able to make a Command for this

But i am not able to make a Command for this

:readmath: value=="CC" || value=="CV"?"on":"off"

And if you change the status? to numeric output you can use:

:readmath: value>0?"on":"off"

Wow, you must be a Doctor or better.....
Thank you very much.

You basically have to add a spy on the communication and then manually decode the protocol.

I often uses this terminal program for it: https://www.compuphase.com/software_termite.htm it has a pass-through  mode that can be used.
It requires 3 serial ports on the computer to do this: One for the original program and two for the terminal program (one in and one out). All can be done with usb adapters.

Thanks for the info. I will have a look in a few weeks.

Hello again

is it possible to put more than one replace in one line?
Original value = OFF -1 CV  -2 CC  -3 CV  -4
Code:
#scpiCmd getStat? txrx? READ
:readmath: getElement(value,2,";")
:readmath: replace(value,"OFF","0")
:readmath: replace(value," -1","")
:readmath: replace(value," -2","")
:readmath: replace(value," -3","")
:readmath: replace(value," -4","")
Result = 0 CV CC CV
Is it possible to make replace(value," -*","") and all channel from 1-4 replaced by ""?

Same question for "getElement"
:readmath: getElement(value,2,";")
:readmath: getElement(value,0)
:readmath: listIndex(value,"OFF CV CC")
Is this possible in one Line? and is this then faster or same speed?

There is no replace with wildcards, but it is a good idea and I will include it in the next release (replaceRX where the from can be regEx, i.e. replaceRX("OFF -1 CV  -2 CC  -3 CV  -4"," -[1234]","") -> OFF CV  CC  CV
)
You can put stuff on one line, you basically have to replace value with the expression from the line above:

replace(replace(replace(replace(replace(getElement(value,2,";"),"OFF","0")," -1","")," -2","")," -3","")" -4","")

It gets a bit messy if you do it too much.

Same question for "getElement"
:readmath: getElement(value,2,";")
:readmath: getElement(value,0)
:readmath: listIndex(value,"OFF CV CC")

Same way:

listIndex(getElement(getElement(value,2,";"),0),"OFF CV CC")

And it will be faster, because the calculator only need to be invoked once.

V2.06 is up
It is a mixed bag of devices and a new popup that gives a visual interface to some chart based commands.
   Added: replaceRX() that is a RegEx version of the replace() function
   Fixed: Riden RD6012 power supply.
   Added: Riden RD6018 power supply (Thanks toddehawk)
   Added: Riden DPH5005 power supply (Thanks rachdatu)
   Added: Manson HCS-3404 power supply (Thanks Scheppo)
   Added: East Tester ET5301 electronic load (Thanks SebiTNT)
   Fixed: GridPanel color selection remembers last selected colors
   Fixed: Table column width can be adjusted.
   Changed: Keysight DS0X2214A to DS0X2024A, the 2214 do not exist according to WS.
   Added: Keysight U1242C DMM (Thanks WS)

   Changed: HP/Agilent 34401A uses handshake for more reliable RS232 communication (Thanks WS).
   Added: Script generation with all settings from layout popup and a bit more to restore a chart layout.
   Changed: Increased maximum number of scale from 6 to 8 due to the easy way to combine scales.
   Added: Layout popup to chart, this can change colors and names, add annotations and reduce number of scales.
   Added: HP E3632A, HP E3633A, HP E3634A Power supplies (Thanks WS)
   Added: Support for RS232 flow control (Only fully supported on Windows)
   Added: HP 6631B, HP 6632B, HP 6633B, HP 6634B Power supplies (Thanks WS)



Colors can easily be changed on different elements on a chart.



Names of the curves can be changed on the chart (these changes will only affect the chart, not anywhere else)



Combine similar scales to get more chart area, due to this I have also increased the maximum from 6 to 8 simultaneous curves.



Annotations can be added here.



When this popup is open it is possible to generate a script with all chart settings

  ReplaceRX is very good

All what i want is now in one Line, and i have learned how this works.

#scpiCmd getStat? txrx? READ
:readmath: listIndex(getElement(replaceRX(getElement(value,2,";")," -[1234]",""),inputValue-1),"OFF CV CC")

I get now for every Channel 0,1 or 2
           
When the electronic Fuse in PS is active, then the value string changes from
"OFF -1 CV  -2 CC  -3 CV  -4" to "OFF F1 CV  F2 CC  F3 CV  F4"
So i change the Part " -[1234]" to " [-F][1234]"
And this works

I have installed Termite and com0com (pass-through). It works pretty well with most of my devices ...except with the Hyperion EOS Suite.
The Suite does work with my device. I can change any parameters. However, as soon as I put the sniffer in between, the Suite doesn't recognized the device 

I am kind of stuck. Do you have any suggestions?
Thanks

Baudrate or handshake. Termite must be set to same baudrate as the program uses.
I am not sure if it will echo the handshake signals or use some standard setting.

Instead of using the com0com software make up a passive spy/tap cable

That is a better solution, but with Termite having two COM ports you can ditch the diodes and resistors and simply directly use the two RX inputs.

We can identify a few things:

The button change status, the "End sound melody" value, the Power values 28.0 and 40.0. These ones multiplied by 10 and convert to hex give
118 and 190). The input voltage value (10.000) multiplied by 1000 and converted to hex give 2710.

Before we go further, is that possible with this info to make a test with TC, create a dialog box and enable/disable the Button sound?

Thanks

Yes, you will want to use the block driver: https://lygte-info.dk/project/TestControllerConfigDevice2%20UK.html#Binary_with_fixed_communication_blocks_(Block)

And you will want to run TC in debug mode (use testControllerDebug.bat) to see exactly what is going on.

Hello HKJ and thanks for your effort and change for us to use your sw
I can see that you have support for UNIT UT61E (serial connection old type)
I have UNIT UT61E+ for USB connection and I cant find that it uses usb2serial.
Do you support this new type and if not do you think you will ?
I cant tell you verison of your sw because I cant find it (files since july of 2020)
Thanks alot

The version can be seen if you select the Configuration page and press About. If you are using TestController with your computer online it will tell you if TestController has been updated.
I will generally recommend to update TestController every few months, i.e. at least 3 to 4 times a year and, of course, more often if you see a interesting feature or device in the update list.

I have not got any code that can handle the serial HID connections that UNI-T uses, I hope to fix that one day. Straight serial connections and socket connections are handled without any problems, it is only the HID connection that is a problem. The reason some DMM's uses HID interface is because it works without a driver, but it requires some special coding to access and that is not covered by standard Java or by the serial library I use.
You can see some of the (good) DMM's I support here: https://lygte-info.dk/info/DMMFrequencyResponse%20UK.html.

Thanks, HKJ, for an amazingly comprehensive program! Very handy for logging from my Keithley 2000 using the GPIB interface (works perfect).

I've crafted a basic configuration for an HP 6624A (four channel power supply) which is attached. I feel like there should be some way that I can simplify things so I don't need SCPI commands for each channel, but I haven't been able to figure out how to pass the channel as a parameter. Any suggestions?

Thanks, it will be included in the next release.
It is missing the #interface definitions, they are used for some functions in TestController.

The #scpiCmd only accept one parameter string, but this string contains all parameters. This means you can use a parameter with both channel and value and then split it up in the actual #scpiCmd definition (Using getElement()).
I.e. something like:
#scpiCmd setV tx VSET(getElement(value,0)),(getElement(value,1))
Would probably (I have not tested it) work with "setV 1 5"

Thanks. I've attached a newer version that includes the #interface definitions. I had them in there originally, but took them out as removing them didn't seem to affect anything (to be honest I'm not sure what Test Controller uses them for).

The #interface is used in scripts, in LogEvent popup and in some panels on GridPanel. They are not required, but it adds some functionality.
In a script this:
=var ps=getDevice("ps");
=setVoltage(ps,5);
=setCurrent(ps,1);
=setOn(ps,1);
Will work with any power supply that as a working interface. Without the interface you would have to use the SCPI commands and they are not the same for all supplies.

You can use the popup "Test interface for current selected device" to test that the functions are working correctly
I doubt they are with this definition:
#scpiCmd setV tx VSET(channel),(value)

Try this one instead:
#scpiCmd setV tx VSET(getElement(value,0)),(getElement(value,1))

Hi,
I recently purchased a Gossen Metrahit Energy with the USB IR interface cable and was excited to run across this software. Unfortunately, the cable doesn't seem to work with my MacBook running 10.15 Catalina or MacMini running Monterey. Normally, a device shows up in the /dev folder with the names cu.usbserial-xxxxx and tty.usbserial-xxxxx. I assume that is the address that the Test Controller program wants. At first I thought it was a FTDI driver problem but other FTDI devices I have do work. I did install the FTDI beta VCP driver 1.4.7 for MacOS 10.15 from their website but no luck.

Has anyone got the Metrahit USB X-Tra cable working with their Mac? I'm looking forward to trying out Test Controller. It looks pretty impressive. Thank you.

Edit:
I am beginning to think that the Gossen cable only works with the supplied driver in Windows. That would be a shame. I have asked Gossen about this and will let you know what they say.

Attached is a updated version of the Siglent SDL10xxXxx definition to fix the mAh vs Ah display and logging table, and incorrect label of the CR mode resistance setting.

Thanks for pointing out the error.

I do not know what chip Gossen uses, but I believe I have seen a user made interface for the Metrahit (Somewhere around here) that uses a standard chip.
