“This product is NOT compatible with your application.” These are the dreaded words that no customer is glad to hear.  Not only were you looking forward to using the device, but now after built anticipation and empty hopes, you are told it will not work.  At Grid Connect  we try to avoid this statement at all costs.  Our technical sales advisory, expert technical support, and vast product versatility give us the tools to make our Bluetooth products work for you.

Recently a customer requested help using our firefly unit with a Siemens DDC.  The only problem was that this DDC required a loop back of hardware flow control pins CTS and RTS.  This is an option normally not supported.

End Device Flow Control Loop-Back

The flow control loop-back is a problem that is normally solved through a custom cable that would be in-between the firefly and the DDC controller.

This was not a possibility for the customer; the firefly needed to be directly plugged into the DDC.  So we tested and came up with a different solution.  We found that jumpering internal pins 6 and 7 of the firefly unit would directly loopback the RTS and CTS pins of the db9.  This is a solution within the firefly and no additional cables would be needed.

Since the jumpers will not fit in a diagonal orientation, we suggest using wire wrapping rather than soldering so not to void our one year warranty.
