I recently ordered some equipment to set up some small RFID demos in a lab environment.
I purchased RB-Asp-01, RB-Asp-04 and RB-Plx-166 to basically hook the thing up to a PC and begin programming with APSX’s .NET dll provided on their site.
I’m completely unable to get any response from the reader at all. When I plug in via USB I see the unit show up on COM3, but it appears to be the Parallax adapter, not necessarily the reader. When I try running ASPX’s demo application I cannot get any reads, writes, or even a reader version. The led’s on the board do not light up when an RFID tag is near, etc. I’ve tried hooking up to a Windows XP and Windows 7 machine with no luck, and am using a 6VDC adapter as specified in the product page.
I tried reaching out to ASPX but they only offer email support and haven’t heard anything in a week. Anyone have any experience using these readers and can point me at something I may be missing? Or did I potentially get a busted unit which could also be a possibility?
Thanks for any help.
What is the max voltage I can use to power the c-100?
Would 4 C size batteries work ok?
What about a 7.4 litho battery?
Thank you,
Steve
When having troubles with a USB-to-Serial converter or adapter, please
follow these steps:
(1)
Make sure the appropriate drivers are loaded and that the module is
recognized by the Operating System. In windows it will show-up as a
COM port and in Linux as a device /dev/ttyUSB0 for instance.
The most common drivers can be found here:
ftdichip.com/FTDrivers.htm
(2)
Once the module is properly installed, do a Loop-back test. This test
consists in connecting the RX line to the TX line and sending messages
through a serial communication program such as Hyperterminal in
Windows. The messages should immediately come back since the lines are
connected together.
(3)
If there are still problems and there are no shorts or power supply
issues, then it is likely the interface is defective and that you will
need to exchange it. Please provide your invoice number and product
code when requesting an exchange.
Let us know if the problem persists.
The C-100 needs 6VDC, 4C batteries (4x1.5 = 6) should be enough but a LiPo can be too much
