EN4000 EchoStream

Serial Receiver

Installation Instructions - 05853A

1 Overview

The EN4000 serial receiver is a gateway that uses reliable frequency-

hopping, spread-spectrum technology to decode radio frequency (RF)

transmissions from end devices and high-power repeaters, and then output

the decoded data to the application controller in a common serial data

format. The EN4000 is used for all one way Inovonics applications.

2 Select the Frequency Band

EchoStream products are able to use a range of radio frequencies, and

must be configured for your geographic area. To configure the serial

receiver:

1. Use a small screwdriver to press the housing release tab (Fig. 1A);

separate the housing.

2. Place a selection jumper on the appropriate frequency band selection

pins (Fig. 1B).

• Leave the jumper off the pins to set the frequency range to 902-928

MHz for North America.

• Place the jumper on the right two pins, marked AUS, to set the

frequency range to 915-928 MHz for Australia.

• Place the jumper on the left two pins, marked NZ, to set the frequency

range to 921-928 MHz for New Zealand.

3. If the serial receiver is powered on, remove the power source to reset.

3 Connect the Serial Cable

Caution: Long cable runs should not be adjacent to high current power

feeds. Keep cable lengths as short as possible to minimize noise pickup.

Measure voltage at the serial receiver on long cable runs.

1. Connect a serial cable to either the serial data port (Fig. 1C) or the

serial data terminal (Fig. 1D). Cabling should meet the following

specifications:

Cable requirements 4-conductor 20AWG (or larger) stranded-tinned

copper with PVC insulation rated to 300 volts at 26°C (80°F). (Belden

#8205, for example.)

Maximum cable length 30.5 meters (100 feet).

2. Route the cabling through either the bottom cabling knockout (Fig. 1E)

or the side cabling knockout (Fig. 1F).

4 Mount the Serial Receiver

Caution: Mount the serial receiver in a location removed from metal. Metal

objects (duct work, wire mesh screens, boxes) will reduce RF range.

1. Use the provided anchors and screws to mount the serial receiver in a

location accessible for future maintenance.

2. Close the serial receiver housing.

5 Serial Receiver Operation

Caution: The EchoStream system should be tested regularly to ensure

operation. To test, place the system in test mode, activate an end device,

and ensure an appropriate response.

The following LEDs are used to monitor serial receiver operation.

Transmit LED Lit when the serial receiver is transmitting data to the

application controller (Fig. 1G).

Receive LED Lit when the serial receiver is receiving data from the

application controller (Fig. 1H).

Decode LED Lit when the serial receiver is decoding an RF transmission

from another Inovonics Wireless device (Fig. 1I).
