Overview:

Air-485

is a high performance 900MHz frequency-hopping spread spectrum (FHSS) long-range

wireless modem. It provides a reliable wireless data link to RS-485 serial devices and offers a

simple yet cost-effective alternative to running costly RS-485 data cables, especially in

commercial environments that make wire connections challenging or impractical.

complicated software to set up the radio and communication parameters. Instead, Air-485

modems are configured through simple DIP switch settings (see Figure 1 and 2 on the following

pages).

Long Range

Indoor/Urban: up to 400 m (1,300 feet) depending on antenna height and RF interference.

Outdoor line-of-sight: up to 10 Km (6 miles) with standard antenna provided.

USB and RS-485 Support

Air-485

modems support both USB and 2-wire RS-485 connections. When connected to the

PC using USB, the device is powered from the USB. When connected to an RS-485 data cable,

flexibility in accommodating even the most complex configuration (examples provided later in

this document.)

Adjustable RF Power Level

Four output power levels (10, 250, 500 and 1000 milliwatts) can be easily set in the field using

two DIP switches. The RF power level should be set higher as needed for longer range. Note

that setting the RF power to a high level when doing testing at very short range (under 2 m/6

feet) can overload the receiver and cause erratic operation.
