addition, the scope can be brought back to its original condition without alteration in the event you
need to send your scope back to the manufacturer or want to sell in the future. The Meade RCDA or
CDA-R will solve your dew problems automatically while informing you every step of the way. Its
like having a hired dew specialist at your disposal.
The Meade CDA-R module incorporates a four port heater capability controlling multiple channels
using multiple channel temperature sensors. For instance, one sensor(DTS-12) may be used for the
main imaging telescopes corrector plate for dew control while the second(DTS-34)is used for another
mounted imaging scope, guider or finder scope or your eyepieces. Each monitored sensor channel
location is then paired with its associated output heat strap channel for dew control. For instance,
DTS12 sensor would be placed on the optical corrector and the heat strap would go around the optical
interface tube for instance CH1 or CH2 or both. The Meade RCDA is a simplified version of the
Meade CDA-R module which incorporates a four port heater capability controlling multiple channels
with manual user switch heat selections (25%, 50% or 80%) for independent control of CH12 or
CH34 PWM heat strap outputs using the provided two independent switch selectors.
In Figure 1 below you can see the normal LX200 GPS/R/ACF, RCX400 ACF, and LX600 battery
compartment, the installed 4 port controller (Model Meade-Meade CDA-R), and the circuit
board with its 4 heat channels and coupled temperature sensor channels(CH1/CH2<--->DTS-
12)(CH3/CH4<--->DTS-34). The center ATHS channel is for ambient temperature and humidity
monitoring normally placed against the optical tube of your main imaging telescope. LEDs next to
CH1/CH2 and CH3/CH4 show the dew control PWM rate when operating.
