1. General
The DX602-C1 is a rugged 2-antenna ‘true’ diversity video receiver
intended for demanding high end video applications. The unit has
special features added for the UAV applications.
It is a analog FM receiver with our intelligent electronics that selects
the best ‘video’ signal to be sent to the output.
The standard audio channel is modified to receive data at 4800 Baud.
The DX602 tuning range is from 2400 MHz to 2500 MHz. (**)
The DX602 receiver has the following standard channels:
A video channel.
A data channel.
(**) Optional - Extended Range from 2150 to 2500 MHz.

2.2.1 Power Input (pins 1 and 8).
a) The DX602 operates off a 9Vdc to 16Vdc unregulated voltage
source with a ripple of less than 0.5Vp.p.
b) Input current at an input voltage of 12Vdc is under 0.6 Amps.
c) Power is switched via an ON/OFF mechanical switch.
d) The DX602 power input is protected against over voltage and
reverse polarity.
2.2.2 Video Output (pins 2 and 3).
a) The DX602 video output is NTSC/PAL/RS170A/CCIR
base-band, 75 Ohm.
b) Output amplitude is 1 V(p.p.) with negative sync tips of 0.3
V(p.p.)
2.2.3 Data Output (Downlink) (pins 4 and 9).
The DX602 data output is at RS232 compatible levels at 4800 Baud.
2.3 Antenna Inputs, total of 2 (Circles 1 & 8 on front panel).
DX602: The tuning frequency range is 2400-2500 MHz, FM
modulated. The antenna connectors are SMA type with a 50 Ω(ohm)
impedance. An option extends the range from 2150 to 2500 MHz.
2.4 RSSI Outputs (pins 10, 14 and pin 8)
The RSSI outputs from both the tuners are brought out for monitoring/
tracking purposes. These are buffered outputs and have a range of
0-4V.
2.5 Remote Programming Connections (pin 6, 7 and pin 9).
The DX602 can be remotely programmed via a RS232C interface.
Data rate is 9600 baud, 8 bits, no parity, ASCII encoded per protocol
described in Appendix A.
