Flaky FastRADs? 3

I have two FastRADs, both purchased within the last year, and neither can maintain a phone connection for more than about 20 seconds. They respond normally to Feature 9**. The only visible problem is that when the RAD is connected to a KSU (both KSUs are MICS with 6.1 or 7.1 software) the power LED blinks about every 8 seconds -- sometimes for 1/10 of a second, sometimes for half a second. The LED does not blink when the RAD is not connected to a KSU. The blinking goes on for as long as the RAD is connected. Changing ports makes no difference.

The fact that I have two doing exactly the same thing and responding normally to Ftr 9** makes me suspect something more subtle than just faulty FastRADs.

The blinking indicates communication between the FastRAD and the MICS. Was a password set in the FastRADs? Have you tried a direct connect to the serial port? Which version of NRU are you using?

Thanks for letting me know the blinking is normal -- I didn't see that in the documentation. Passwords are set in both RADs; I tried direct serial communication with one of them, without success. The NRU version is 10.0.

I also have a flaky FastRAD - is there any way to obtain the firmware update?

I tried the link, but it does not seem to work anymore.

using NRU v10 to connect to MICS v4.1 - my FastRAD says does not respond. This is trying 9600 and 19200 as baud rate when connecting directly.

my FastRAD is model NT8B80AAAB

Any help would be greatly appreciated.

I can access RAD using F** and can set password ok (in this case it is set to 12345678).

It seems like the only problem is getting into the RAD via serial connection as since the status msg can be applied to multiple problems I am unsure which direction to go.

I have tried 2 older M-F DB9 cables and have also purchased 2 new ones, in case one of the new cables was bad.

I'd suggest putting up a new post rather than adding to this thread -- it's pretty old. I think we're the only people looking at it, and neither of us knows what's causing your problem. (Mine was caused by a flaky modem, there was nothing wrong with the FastRADs.)

My suggestion may be way off but if you haven't tried a null modem cable...that may be the reason you cannot establish initial connection.

I have a RAD that works fine when Operator Assisted but when telling the RAD to answer a target line it does not answer....will the patch fix this too?.
