IO Error - Mac 10.7.5 #2

Closed kylebjordahl closed 1 year ago

kylebjordahl commented 11 years ago

So, I'm not the sharpest with Python, here's what I'm getting:

Using device /dev/cu.usbserial... Traceback (most recent call last): File "cs1504.py", line 323, in scanner.interrogate() File "cs1504.py", line 167, in interrogate raise IOError IOError

I don't mind tinkering in the code, but do you have any ideas what might be causing it to timeout? I believe I have the correct drivers installed, and the port is showing up in /dev/.

Using Mac OS X 10.7.5 and Python 2.7.1 (OS default, I think)

is it running as root? I had a problem that I couldn't connect because I wasn't root.

I ran as root and similar thing happened. CS1504 scanner blinks but nothing happens.

I have just acquired one of these scanners and was hoping that I could use your script to drive it. Using OS 10.11, Python 2.7 I get exactly the same error as @kylebjordahl. The program loops around self.send('\x01\x02\x00') 50 times and then fails. The /dev/ttyusb entry is showing up when the converter is plugged in and the LED flashes during the connection process. Running as root makes no difference. I can connect using the CS1504 'Mini Utility' using VirtualBox and Windows which leads me to believe that all the hardware and serial to USB converter is OK. I have tried adding self.ser.setDTR(1) to the end of the definit section (as a previous user suggested) but no luck. Any advice? I appreciate that this device and this thread are now quite old but I know that these scanners are still being used.

Please ignore above - I have now identified that this is a driver issue. After updating the Prolific Driver to the version from www.mac-usb-serial.com whic seems to have solved the issue. Get what you pay for - FTDI chips never caused me this grief!

I'm glad you figured it out. We eventually abandoned these scanners in favor of CS3000's.

I hope the driver update might improve the connection to a couple of cheap arduino clones too. I needed a cheap barcode scanner and picked up the 1504 for £4 so a bit of a bargain and your software clinched the deal!

Glad you found it useful. I haven't used it in a long time, as I myself switched to Delicious Library with its RoV Bluetooth scanner.
