Does anyone know the pinout of the Orion Intelliscope RJ12 style serial port connector. I want to make a cable for a friend's Intelliscope Dob to connect to the Nexus RJ12 connector. I have an unused Nexus that I will give him to act as a serial to Wifi access point for Sky Safari on his Tablet. I don't want to spend $16 on a connector from Orion just to figure out it's pinout. I can't find the details from the Intelliscope manual. He lives about an hour out of town and I would prefer to show up with a working cable and not have to troubleshoot a new cable in the field. Using the Orion Intelliscope to PC-232 cable plus the Nexus RJ12 to DB9 connector just seems to be a lot of extra bulk compared to a custom RJ12-RJ12 cable.

 

The Nexus pinout is here:

 

Pin 1 Ground,

Pin 2 TxD – transmitted data (output)

Pin 3 RxD – received data (input)
Pin 4 Ground
Pin 5 Ground 
Pin 6 No Connection

 

I bought the NexusDSC so I really don't have a need for the Nexus anymore.

Thanks for the Link. Info from the linked page:

 

Pin 1 from the Orion computer is RS232 transmit, which should be connected to pin 2 of a standard PC DB-9 connector.   Pin 2 from the Orion computer is RS232 recieve, which should be connected to pin 3 of the DB-9.   pin 3 from the Orion computer is ground, which should be connected to pin 5 of the DB-9.

 

Looks pretty easy. I can use a 4 conductor flat wire and leave pins 1 and 6 empty. Pin 2 and 3 get rolled in the cable. Pin 4 goes straight through.

I'm kind of interested down the road about installing that resistor to the controller screen to keep it warm.....using a Lithium battery helps a bit though....
