DCS400 Multipurpose Connector

R/C Switch Blimp Cameras


This special connector was modified to switch two cameras (one infra red, 1 ultra violet) on via a tethered blimp from a height of up to 3000 feet (1KM).The transmitter/receiver pair itself can handle up to 5KM, so more than enough power.System was for Professor Richard Heck, Land Resources Department, University of Guelph.

1. The battery charger input must be a 15 volt DC regulated supply current limited to 2.5 amps.The supply must current limit linearly and must be capable of prolonged operation in current limit.Exceeding 15 volts or 2.5 amps may permanently damage the DCS.The DCS has been tested to comply with safety and electromagnetic interference regulations only with the power supply provided.Use of any other supply is not recommended.

2. The serial port TXD and RXD pins are 5 volt CMOS logic.Serial parameters are 19200 baud, 1 start bit, 8 data bits, 2 stop bits, no parity.

3. The remote release pin is a three level input.When active, it is pulled to 5 volts (internally) by a 10K resistor in the DCS.To wake up the camera (equivalent to lightly pressing the N90 shutter release), the pin must be pulled down to between 1 and 3 volts.This may be accomplished by connecting a 10K resistor to ground.
To relase the shutter, the pin must be grounded.The shutter may be released without using the wake up feature.

4.Make NO connections to the filter wheel motor and sensor pins.
