Add a Routing Device

• In areas that have weak RF coverage (for example, where RSSI < -78dB), configure a VP Series 2000

device to enable routing or, preferably, add a VP Series 2000 routing device.

• Use your network vendor's software to verify, and if necessary, enable the router function of each

VP Series 2000 device.

• Verify that each device has a good network connection.

• Remember to stay within the recommended number of hops per device. (See the "Plan Device

Placement" section).

! Note

VP Series 2000 ISA100 devices must be set as IO/Router device types and you may also need to enable

the join property

when routing is enabled.

Using a VP Series 2000 ISA100 sensor as a router decreases its battery life.

ISA100 network device managers may limit the number or IO/Router enabled devices. Refer to the

vendors documentation for details

Move the Device, Backbone Router or Access Point

Relocating a device or reorienting its axis or orientation relative to the router or access point as little as

6 cm (2 1/3 inch), or one-half of a 2.4 GHz wavelength, may improve signal strength. VP Series 2000

devices are designed for optimal RF propagation when the device's axial alignment is in the vertical

plane. If unable to mount the device vertically, the preferred orientation is with the X-axis in the

horizontal plane.

Change Backbone Router or Access Points

• If permitted, use a higher gain antenna on the backbone router or access point. Verify that the

resulting narrowly focused radio frequency distribution pattern meets your needs.

• Modify the antenna polarization of the backbone router or access point.

• Add a backbone router or access point.

Verify Signal Strength and Packet Error Rates

Check that the devices' signal strength and packet error rate are within your network vendor's

guidelines. Use your wireless network gateway to monitor device signal strength and packet error rates.

• Signal strength (RSSI) must be above -85 dBm, and preferably above -78 dBm.

• For ISA 100 networks the packet error rate (PER) should be less than 50%, and preferably less than

20%.
