The network coordinator is a gateway that uses reliable frequency-hopping, spread-spectrum 
technology to coordinate signals between end devices, high-power repeaters and the 
application controller in a common serial data format.

If you have any problems with this procedure, contact Inovonics Wireless technical services:

•  E-mail: support@inovonics.com

•  Phone: (800) 782-2709; (303) 939-9336

EchoStream products are able to use a range of radio frequencies, and must be configured for 
your geographic area. To configure the network coordinator:

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

Place a selection jumper on the appropriate frequency band selection pins (Fig. 1B).

•  Place the jumper on the left two pins, marked AUS, to set the frequency range to 915-
928 MHz for Australia.

•  Place the jumper on the right two pins, marked NZ, to set the frequency range to 921-
928 MHz for New Zealand.

•  Leave jumper off the pins to set the frequency range to 902-928 MHz for North 
America.

If network coordinator is powered on, press Reset to configure.

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 network 
coordinator on long cable runs.

Connect power cabling to the power terminal (Fig. 1C). Power cabling should meet the 

following specifications:

2-conductor 20AWG (or larger) stranded-tinned copper with PVC 

insulation rated to 300 volts at 26°C (80°F). (Belden #8205, for example.)

30.5 meters (100 feet).

Connect a serial cable to the serial data terminal (Fig. 1D). Cabling should meet the 

following specifications:

15.25 meters (50 feet).

If an external tamper switch is needed, connect a cable to the tamper terminal (Fig. 1E). 

Tamper cabling should meet the following specifications:

100 meters (328 feet).

Route the cabling through the side cabling knockout (Fig. 1F).

Mount the network coordinator in a location removed from metal. Metal objects 

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

Use the provided anchors and screws to mount the network coordinator in a location 

accessible for future maintenance.

Close the network coordinator housing.

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 network coordinator operation.

Lit when the network coordinator is receiving serial data from the 

application controller (Fig. 1G).

Lit when the network coordinator is transmitting serial data to the 

application controller (Fig. 1H).

Lit when the network coordinator is receiving a RF transmission from 

another Inovonics Wireless device (Fig. 1I).

Lit when the network coordinator is transmitting an RF transmission to an 

end device or high-power repeater (Fig. 1J).

Lit when the network coordinator is receiving power (Fig. 1K).

The following buttons/controls are used during operation:

Press to restart the network coordinator after a configuration change (Fig. 1L).

Sends an alarm when the network coordinator housing is opened (Fig. 1M).
