The Prima Luce Lab ECCO-NTC adapter allows you to use the ECCO 2 environmental computerized controller with Celestron dew heater rings. 

Celestron dew heater rings differ from standard dew heater straps, as they utilize an NTC thermistor to measure temperature of Schmidt-Cassegrain or aplanatic SC telescopes' corrector plate without the need for an external temperature probe. By using the ECCO 2 environmental controller in combination with these rings, you will have a fully-featured automatic dew heater and environment monitoring setup!

Note: The ECCO-NTC is not compatible with the first generation ECCO controller.

The ECCO-NTC is small, lightweight and fits in a standard finder-style saddle for convenience. It does not need external power source - just connect it to the ECCO 2 via the included 3.5mm male to male cable.

Instructions for use:

1. Insert ECCO2 body into ECCO-NTC and lock it with the 2 grub screws.
2. Connect the "12VDC 5.5/2.1 mm to RCA power cable" (that is included with the Dew Heater Ring) to one of the EAGLE's dew heater ports.
3. Connect "3.5mm to 3.5mm power jack cable" to ECCO's port number corresponding to the EAGLE's dew heater port you connected the "12VDC 5.5/2.1 mm to RCA power cable". For example: if you connect dew ring power cable to EAGLE's port number 6, you have to connect this "3.5mm to 3.5mm power jack cable" to port 6 of the ECCO2.
4. Connect the other side of this "3.5mm to 3.5mm power jack cable" to 3.5mm port on one side of the ECCO-NTC.
5. Connect the "2.5mm to 2.5mm cable" to port 2.5mm port on one side of the ECCO-NTC and to the thermistor jack of dew ring.
6. Connect the "USB-C port to USB-A port cable" (that is included with ECCO2) to ECCO2 and to EAGLE (compatible with EAGLE models with dew heater ports).
