Four years later, still more questions on reading digital inputs. I have two ADC24 units; for each unit, I am setting up my DIO lines by calling HRDLSetDigitalIOChannel with the following binary parameters: dirOut = 0101 digOutPinState = 0101 enableDigIn = 0010 One unit has its digital input D2 (bit...

Never mind, I figured it out. It looks like the same HRDLGetSingleValue can be used to read the digital port as channel 0. I wish the documentation for the SDK were more explicit about it. Thanks!

Hi, I have a question about the ADC SDK: I've been able to successfully read analog inputs using HRDLGetSingleValue. In addition to this, I need to be able to set some digital lines as outputs and some as inputs and then read digital inputs in single-shot (nonbuffered) mode. I've been able to set di...

Hi,

We use your USB TC08 with our software (communicating through usbtc08.dll). Can you offer any guidelines on programmatically detecting open and shorted thermocouples?

Thanks,

Hi, I have a program that supports old legacy serial TC08; we use USB-COM adapters based on FTDI chips. Recently I came across the following issue: if the adapter is assigned COM port numbers below 10, both PicoLog Recorder and my program (which uses tc0832.dll) work fine, but if COM ports are highe...

Most likely, the problem arises from either the driver for the serial TC-08 or the driver for your USB-COM adapter not being stable on a multicore system. Therefore (1) make sure you are using the latest driver for your USB-COM adapter; (2) when running your application, set its affinity to CPU-0 on...

Hi,

With USB-based TC-08, it is possible to retrieve the unit's serial number using its API. Is it possible with RS232-based TC-08? I could not find a applicable function in tc0832.dll. Are there any other API's available that support RS232-based TC-08?

Thanks!

Thanks Mark, it worked for me. I have another question though: When I distribute my application, I don't know whether the end user will be installing it on a 32-bit or 64-bit machine. I guess I can add a batch file to my installer that will either add picopp.inf and picopp.sys files to desired folde...

[quote="markB"]It is possible to do a silent install using our installer but it would mean that you would need a ~27MB installer to deploy only ~340kB of files. You only require three files to deploy the drivers yourself: [list]1) in your application directory: usbtc08.dll 2) C:\windows\system32\dri...

Sorry, I did not clarify that I was using the TC-08 API - I write my own programs to communicate with the logger. I was quoting from the description of the function "usb_tc08_set_channel". I hope that using the "X" parameter for "tc_type" is still valid.

Thanks,

According to the manual, if I set the thermocouple type for TC-08 to "X", the output will be reported as millivolts. Is it safe to assume that the cold junction temperature does not affect the measurement results, but I can still poll this parameter to monitor the internal temperature of the unit? T...

Mark,

This info is exactly what I was looking for! I'll give it a try. Thanks a lot!

Hello! We use TC08 USB as an OEM part in a larger system controlled by our own software. Therefore a question: is it possible to install just the driver for TC08 USB without installing PicoLog? Ideally, we would prefer completely "silent" installation. It is also acceptable to go through "New Hardwa...

Ziko,

That's just what I needed. Many thanks!

Sergey

Hello Ziko, Thank you for the prompt reply. Actually, in the past, I used both serial and USB TC-08. I believe that the manufacturer of the instrument for which I wrote my software switched to ADC-24. Therefore I have a related question/request: I downloaded the latest full installation of PicoLog a...
