Visual Signal Level Indication

The built-in continuous signal strength diagnostic test that can be initiated from any remote Air-

485

modem references the base modem and provides real-time signal strength indication

using three green LEDs (Figure 2). This feature helps the installer in terms of choosing the

correct location and elevation of the Air-485

modems and the alignment of the antennas for

maximum signal strength. This also eliminates the need for expensive tools and power meters.

Multiple Network Support

Because the range of the Air-485

modems can be up to 10 Km (6 miles) line-of-sight, it is

possible that installations in close proximity could interfere with each other. To address this, the

modems have two DIP switches which allow up to four Network ID numbers to be specified. For

example, an Air-485

Master which is set to ID 1 will only wirelessly communicate with Air-485

Slaves with ID 1. Transmission from other ID numbers will be ignored.

Secure Data Communications

Air-485

modems use 128-bit Advanced Encryption Standard (AES) to ensure that the data

integrity is not compromised.

Multiple Slave Units

A single master AIR-485 unit can communicate with up to 16 slave units.
