For reason I cannot correct, AN will not connect to ServoCAT. ? All was working well until the connection failed the next time I used my OTA. ?AN is functioning normally. ?After the usual startup protocol and a 2 star alignment, the encoders are functioning normally guiding me as I “push to” my target. ?Also when I power on the hand control, the function buttons all are working normally when I engage the ALT/AZ motor drives. ?What I don’t hear is the series of 3 double beeps after I power-up and turn on AN to indicate the 2 units have made connection. ?In AN under settings/SERIAL I have the correct parameters: SERIAL 1, BAUD rate, and ServoCAT. ?I have read through the manual but have not found anything that I have missed or not engaged correctly. ?It occurs whether I power by lithium battery or use the AC adapter for power. ?Again it was working fine until it failed and I cannot think of anything that may have happened. ?Any suggestions on what the problem may be? ?

Hi Mike,

Firstly check the LED on the ServoCAT labelled DSC.

When you first interface Argo Navis and ServoCAT and power the two on, that DSC LED should begin blinking.
The two units have an initial little chit chat with each other and the ServoCAT then blinks the DSC LED to denote that communication
between the two is successful.

After a completed successful star alignment, the DSC LED should go steady ON.

Argo Navis has two serial ports, SERIAL 1 and SERIAL 2. Double check that the cable is plugged into the correct serial port.
Verify that you are using the correct cable to interface between the two. Whilst there are other cables that look similar, they will
almost certainly be wired differently and not work.
Since Argo Navis has two serial ports, you could also configure the "other" port to have a STARTUP of navis and a BAUD rate of 19200,
power the unit OFF, move the cable to the "other" port and then see whether the ServoCAT DSC LED flashes.

Email us if you require further assistance.

Mike,

I've responded to both your emails ... the 2nd response, because it was obvious you didn't get the first, was sent out using a different email address. please check your spam folder.?
