Do you stock obsolete wireless I/O bridges?

Yes. Discontinued Banner SureCross first generations, retired Phoenix Contact Radioline early codes, end-of-life ProSoft Wireless, and earlier Moxa AWK are sourced through our supplier network.

900 MHz vs. 2.4 GHz — which should I use?

900 MHz for long-range, low-bandwidth telemetry through obstructions — ranges of kilometers with good antennas. 2.4 GHz for higher bandwidth at shorter range, but more interference. For point-to-point I/O at 1+ km, 900 MHz is usually better.

Do I need a license to use this?

ISM bands (900 MHz, 2.4 GHz, 5 GHz in US) are unlicensed for general use within regulatory power limits. Licensed VHF/UHF bands require an FCC or country-equivalent license but offer interference-free operation and longer range.

Will my old wireless I/O configuration work on a replacement?

If the model and firmware match, yes — configuration files load from the OEM software. Pairing emitter-receiver pairs often requires a manual pair-binding step after replacement.

Can I extend Ethernet wirelessly between buildings?

Yes — industrial Wi-Fi access points in bridge mode or licensed-band point-to-point links handle building-to-building Ethernet. Range depends on line-of-sight, antennas, and licensed/unlicensed band choice. Outdoor-rated equipment is required.

What is the warranty?

12-month functional warranty. Damage from antenna surge (lightning), over-voltage, or operation outside rated environment is not covered. Surge protection on antenna lines is strongly recommended.
