There does seem to be a parsing error in waveform subrecords.

Will let you know when I fix this. 1 month agopostedonHi John, appreciate the rapid response. And thanks very much for looking into this. I'd overlooked the.raw files! In generating some example debug files, I've established the following: a) same issue occurs with v1.006/5/4 - i.e. No waveforms runs fine, falls over after initial 1-2 readings when acquiring waveform data.

1.003 has weird behaviour where it immediately starts printing raw data into the command line, but we probably don't need to get into that! b) I am using FTDI chipset c) behaviour. 1 month agopostedonHi Stephen, Could you send me or attach here the.raw debug files generated by the app (from the app folder when the error occurs)? Will check if it's a parsing issue/bug.

Does the same issue occur with an older version of VSCapture? Also it is recommended to use FTDI chipset based usb serial cables with updated drivers for optimal performance, as other chipsets have drivers that seem to drop data with fast requests. Thanks, John. 1 month agopostedonHi John (and others), just wondering if anyone else has experienced problems with VSCapture (v1.007) in Windows10? We have been able to run the programme successfully without waveform data transmission (option '0'), but requesting waveforms causes the programme to fall over.

I see two behaviours: 1) receives 1-2 transmissions and then simply hangs 2) as above, but quickly flashes the following text in the Cmd line before the window closes - 'Error opening/writing to serial port:: The I/O operation. 2 months agopostedonHi Paolo, If you want LAN option and only CSV export then it should be, for example: mono VSCaptureRcAstm.exe -portoption 2 -serverport 4174 -export 1 The port name is only for serial ports!

Do you have an idea from where I can get the protocol? Do have a PDF or something like that?

Thank you very much for your help. Xavier. 4 months agopostedonHi, If you mean setting the S/5 monitor time through the RS232 interface, it may not be possible. Not sure if an API for that exists (you have to do time update manually through service mode). Instead you can capture S/5 data using VSCapture to a device like RaspberryPi which is time synchronized with a NTP server. The app source can be modified to use system timestamps rather than monitor time. John.

Xavier. 5 months agopostedonVSCaptureDash should work with GE Dash 3000/4000/5000 series monitors via AUX port. But I've not tested Dash 2500 (GE manuals mention Dash 2000 series to be similar to others, it may work). Did you try using the correct port and cable wiring as mentioned in the thread above?.

5 months agopostedonGuys, I try to collect data from a Dash 2500 without success now. Do you think it is compatible with VsCaptureDash? Thank you in advance. Xavier. 6 months agopostedonATEN cable drivers are probably inbuilt in the GE device, not sure if others might work.

A null modem cable is generally needed to connect the GE device to a RS232 serial port. If your PC already has a hardware serial port, you may not need a usb serial cable at the PC end. In RaspberryPi, it has been tested with usb serial cables rather than in-built GPIO pins. Did you get it working?.

6 months agopostedonAfter checking the B650 admin page USB connection. B650 is actully recognized the serial to USB cable. I suppose it is not that important to use ATEN cable. I will test it with ATEN next time. And a further question, if the PC, or the Rasberry Pi I mentioned above, has got a COM port, am I really need that null modem cable and the other USB adapter to connect?

This must be connected into a null modem serial cable, connected to a generic usb serial cable (interfaced with recording PC). Check your cables, it should work. 6 months agopostedonHi guys, I have test the B650 with VSCapture and got nothing. I connected the PC with B650 using 2 serial to USB adapter(FTDI chip) and a RS232 female to female cable(not sure null modem or not). Actually, I have a Rasberry Pi with COM port, which is able to connect to the B650 with only 1 adapter.

8 months agomodifiedonHi Bill, Due to hardware bandwidth limitations, the waveform export priority option must be set before capture. Certain waveforms like ECG use more bandwidth than other waveforms (500 or 250 samples/sec in ECG compared with 125 or 62.5 samples/sec for other waveforms). So selecting 3 ECG waveforms, for example, would utilise the full bandwidth, while it would take 8 non-ECG waveforms to do so. So selecting option 9 can result in dropped packets. If your study is only interested in a single arterial. 8 months agopostedonHi Bill, Due to hardware bandwidth limitations, the waveform export priority option must be set before capture.

8 months agopostedonFirst of all, I would like to thank you for developing and supplying this valuable tool! I am having problems acquiring arterial waveform data. I have been attempting to conduct analysis of the waveforms from a Philips Intellivue MP70 monitoring patients in our ICU. I am using a dedicated MP70 with static IP address that I move the transducers (from the wall-mounted mp70) to during the data acquisition period.

I have chosen this method because the RS232 port seems to drop too much data, and the bedside. 8 months agopostedonThere's another solution you can try with the serial splitter scenario. But you would need to modify and recompile the source code (download from this site). You could comment out the part which requests data in one app (PC2), so that it becomes a passive listener, while the app in PC1 runs unmodified and requests data on behalf of both apps. In Main.cs file in source code, look for these lines and comment it out (use // before each line). Then recompile the code in Visual Studio.

//Request transfer. 8 months agopostedonHi John, Thank you for the suggestions. The real-time analysis is done in Matlab, so the input format is very flexible. Currently I just read in the entire.csv file as it's being written to (about once per second) since the file size is tiny. I have considered that maybe the issue occurs if the file is being read at the same time as VSCapture tries to write to it, but I ruled this out as the issue does not occur when running the real-time analysis only (i.e. Not collecting continuous data on a separate.

8 months agopostedonHi Jostein, The chipset you mentioned is Prolific, which is different from FTDI. But the most probable reason for the issues could be the data request being sent by two machines at the same time (through the splitter cable) to the monitor. The GE machine probably was not designed to handle two simultaneous requests. We might have to think of alternative options to transport data. What format does the real time analytics support for input? What if a copy is sent/streamed to a Webserver that accepts. 8 months agopostedonHi John, I'm unsure what chipset my serial cables and serial splitter are, but the serial-to-USB adapter is using 'Prolific - PL2303RA' according to the product page.

Though as I have had absolutely no problems with VSCapture when sampling to one computer only, even when two computers are connected, I'm inclined to rule out the cables being the issue. I will nevertheless check if my drivers are up to date. The issue has only ever occured when sampling to two separate PCs simultaneously. One of the. 9 months agopostedonHi Jostein, Are you using FTDI chipset based serial cables? Serial cables with these chipsets seem to give optimal performance. Other serial cables may have dodgy serial drivers that cause memory leaks and communication drop outs.

Also update the serial cable drivers used in your OS (is your environment Windows?). Using VSCapture with a serial splitter hasn't been tested, could you give me a background of your study? Other options can be attempted. Polling requests from two PCs connected to the same. 9 months agopostedonI am having an issue with VSCaptureWavev1.005.exe stopping sampling (seemingly) at random when trying to export data from a GE S/5 monitor to two separate computers simultaneously using a serial splitter cable. Each instance of VSCapture will record data just fine for a while, sometimes for about an hour or more, but eventually both instances will stop receiving samples. This has never occured when running only a single instance of VSCapture, so I assume the issue has to do with running two separate.

9 months agopostedonExcellent, thank you John. I just ordered an MP70 with M3001A - nice gear! Will let you know how it works in a few days. Best, -Alex P.S. I also ended up getting an M1027A EEG module, not sure if you've had a chance to try one of those, if not I'd be happy to test it. 9 months agopostedonIn terms of capability of hardware for research, data bandwidth, code support for waveform output, the Philips Intellivue MP or MX series would be a recommeded option.

Hello, I'm trying to control the genesys TDK-L ambda 750W power supply through serial communication(Through hyperterminal). I have connected my power supply with the PC using a RS 232 cable with DB25 and Rj-45 connectors. THe power supplu has the following settings:Bits per second:9600(Default)Parity:NoneAddress:06(Default)For serial communication the power supply is setted to use RS232 in the rear panel.I have verified the address, the baud-rate, the switches on the rear of the instrument, but it appears all ok.I have verified the COM in the PC, too.but it doesn't talk with the tdk lambda. When I send 'ADR 06' to the power source through hyperterminal it should say 'OK', but I read onlyADR 06ADR 06I don't know whether the communication port on the power supply is enabled or not.could any please help. Mraya001, were you able to get this to work? I have the same Lambda power supply with the Lambda-supplied RJ45 to DB9 RS-232 cable and I get no response from the power supply whatsoever, just a timeout.The port on the supply is enabled as far, as I can tell from the documentation.

The PC's serial port is functioning because I can use the NI-MAX VISA Test Panel to communicate with two other devices that are presently sitting on my desk.Unless I missed it, the documentation does not say anything about having to send special termination characters, but it wouldn't surprize me if that's what it is. Ok, I got this to work using the VISA Test Panel in NI-MAX. It was the termination string which Dennis alluded to in a previous post.Make sure you uncheck Send End On Writes. The power supply requires only a carriage return after a command. Nothing more, nothing less.

Oddly, it will not work if you check Enable Termination Character. Once I unchecked those and manually added the r to the end of my command strings, everything worked. Also note that the supply will not respond if it doesn't get a ADRs06r as the first command in a 'session' (the s and r are just visual representatives of a space and a carriage return respectively. 06 is the factory default address setting).(edited for spelling).
