The DX502 tuning range is from 900 MHz to 928 MHz. (*)
The DX602 tuning range is from 2400 MHz to 2500 MHz. (**)
NOTE
Unless explicitly stated, every reference in this document to
the DX602 also implies the DX402 and DX502. The main
difference between the models is the frequency range.
The DX602 receiver has the following standard channels:
A video channel.
An audio channel.
And the following optional features:
Broadcasting industry options
• Remote synthesizing of a TX600, TX623 or TX630.
• Talk back audio channel.
• Lemo interface connectors.
Security industry options
• Remote control of the receiver via RS232.
• Remote synthesizing of a TX600, TX623 or TX630.

Interface.
The DX402/DX502/DX602 can be remotely programmed via an
RS232C interface. The data rate is set to 9600 Baud, 8 bits, no
parity, 1 stop bit and no handshaking signals. Data is ASCII encoded.

Protocol.
<Frequency> <CR> where frequency is any frequency in the tuning
range of the receiver in increments of 250KHz.
E.G.: DX602 -> 2400 <CR> will tune in to 2400MHz
2413.25 <CR> will tune in to 2413.25MHz
