1. General

The DX404/DX504/DX604 are rugged 4-antenna ‘true’ diversity video
and audio receivers intended for demanding high end video
applications.

The DX404 NTSC model tuning range is from 56MHz to 802.25MHz
The DX404 PAL model tuning range is from 56MHz to 860MHz.
The DX504 tuning range is from 900 MHz to 928 MHz (2150 MHz
with Option 4)
The DX604 tuning range is from 2350 MHz to 2500 MHz (2150 to
2500 MHz with Option 4).

All receivers have the following standard feature:
One FM modulated (AM/VSB for DX404) video channel

Two (1 for DX404) FM modulated audio channels
And the following optional features:

Broadcasting industry options

* Talk back audio channel
* Remote control of the receiver via RS232

Security industry options

* Serial communication (RS485/RS422) input port for Pan/Tilt/Zoom
control
* Alarm output
* 3 analog telemetry outputs
* Remote control of the receiver via RS232

Unless explicitly stated, every reference in this document to the
DX604 also implies the DX404 and DX504. The main difference
between the models is the frequency range.

2. Specifications

2.1 Power Input (Circle 9 on rear panel).

a) The power input connector is a XLR 4 pin on the rear panel of the

DX604.
Pin 1 – Ground
Pin 2 – RS232 Interface (Transmit)
Pin 3 – RS232 Interface (Receive)
Pin 4 - +9Vdc to +16Vdc

Figure C – Power Input

b) The DX604 operates off a 9Vdc to 16Vdc unregulated voltage

source with a ripple of less than 0.5Vp.p.
c) Input Current is under 1 Amp at an input voltage of 12Vdc.
d) Power is switched via an ON/OFF mechanical switch.
e) The DX604 power input is protected against over voltage and

reverse polarity.

A bi-color LED on the rear panel indicates the condition. Yellow

indicates over voltage and Red indicates reverse polarity.

NOTE

f) The RS232 interface option on pins 2 and 3 is used to remotely

program and setup the DX604 as described in Appendix B.

2.2 Antenna Inputs, total of 4 (Circles 1,2,5,6 on rear panel).
a) DX404: The tuning frequency range is 56MHz-802/860MHz,

AM/VSB modulated. The antenna connectors of the NTSC model
are “F” type with a 75 Ω (ohm) impedance. The PAL model has
RCA connectors.

b) DX504: The tuning frequency range is 900-928 MHz, FM

modulated. The antenna connectors are “F” type with a 75 Ω
(ohm) impedance.

c) DX604: The tuning frequency range is 2350-2500 MHz, FM

modulated. The antenna connectors are SMA type with a 50 Ω
(ohm) impedance.

2.3 Video Output (circle 11 on rear panel)
The video output through a 75 Ω (ohm) BNC connector.
a) Output is NTSC/PAL/RS170A/CCIR baseband from 20 Hz to 5.5

MHz.

b) Output amplitude is 1 Vp.p. with negative sync tips of 0.3 Vp.p.

2.4 Audio Outputs (Circles 7,8 on rear panel)
Both audio outputs are XLR 3 pin connectors located on the rear

panel.

Pin 1 – Ground
Pin 2 – Audio Output (P)
Pin 3 – Audio Output (N)

Figure D – Audio Output(s)

Output is 1 V (peak to peak) into 600 Ω (ohm), balanced.
