FBL2360 Status LED output

I would like to have an external status LED for my FBL2360 application because the controller is not easily visible. I have used the Roborun+ utility to define the function of DOUT4 to be "StatusLED" and saved that to the controller. But, when I monitor the voltage on pin 7 (DOUT4) I get nothing, yet the status LED on the controller is blinking nicely (3 short green pulses in my case to indicate analog command mode).

Am I misunderstanding the function of the StatusLED output?

BTW, I have tried defining DOUT4 to be Active High and Active Low. Both produce the same 0V when pin 7 is measured w.r.t GND (pin 1) but things are mysteriously different when pin 7 is measured w.r.t +5 (pin 25). With DOUT4 set to Active Low, pin 7 measured 5 volts below pin 25...i.e. at ground. But when DOUT4 is set to Active HIGH, pin 7 measures only about 3 volts below pin 25...! It's as if pin 7 is in a high impedance output state and not being driven at all by the controller...

Thanks for any assistance.

Sorry, I forgot to mention that I already tried that LED idea. I used a small LED and a 240 ohm R in series and connected it both from DOUT4 to GND and from +5 to DOUT4 and it never flashed. To test the LED+R combo (and to get the polarity right), I connected it from +5 to GND and it glowed steadily.

I'm away from the unit now and, unfortunately, I'm not 100% sure that I tried all these combinations both with DOUT4 set to Active High and to Active Low. Which of those settings should I use for a Status LED? Assuming I did try them all, then it looks to me like DOUT4 simply does not work for a StatusLED. Of course, all this is assuming that the StatusLED output mimics the behavior of the built-in status LED, which was showing three short green flashes all the while I was doing this testing. Could yall check it there on one of your FBL controllers please?

Thanks,

Scott
