3 Setup the EN7286NX
3.1 Select the Frequency Band
EchoStream products are able to use a range of radio frequencies, and
must be configured for your geographic area. By default, the EN7286NX is
set for the United States. If you want to configure the EN7286NX for a
different geographic area:
1. Use a small screwdriver to press the housing release tab (Figure 1, A);
separate the housing.
2. Place a selection jumper on the appropriate frequency band selection
pins (Figure 1, L).
• Leave the jumper off the pins to set the frequency range to 902-928
MHz for North America.
• Place the jumper on the top two pins, marked AUS, to set the
frequency range to 915-928 MHz for Australia.
• Place the jumper on the bottom two pins, marked NZ, to set the
frequency range to 921-928 MHz for New Zealand.
3. Remove the power source to reset.
3.2 Connect the EN7286NX to the NX Panel
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 interface on long cable runs.
1. Connect the serial receiver interface data terminal block (Figure 1, G) to
the NX Panel. 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).
• Connect POS on the power/data terminal block (Figure 1, G) to POS
on the GE NetworX Panel.
• Connect COM on the power/data terminal block (Figure 1, G) to COM
on the GE NetworX Panel.
• Connect DATA on the power/data terminal block (Figure 1, G) to DATA
on the GE NetworX Panel.
2. Connect the relay 1 (Figure 1, E) and 2 (Figure 1, F) terminal blocks to
external devices as desired.
3.3 Set the Serial Receiver Interface Address
Dipswitches 1 and 2 (Figure 1, H) are used to set the serial receiver
interface address. Use the following table to choose settings appropriate
for your installation:
Once you have made your selection, you will need to cycle power to
complete the interface address change.
3.4 Set Functions on Four-Button Transmitters
Dipswitches 3 and 4 (Figure 1, H) are used to set the functionality of
buttons 3 and 4 on four-button transmitters.
