2. PRODUCT OVERVIEW
LinkWiser™-S400M Rev. 2.1
Narrowband multi-channel data radio modem
LinkWiser™-S400M Rev. 2.1 series support a narrowband, 12.5KHz channel spacing and an
exceptional receiver sensitivity, -113dBm and is a complete wire-replacement solution (RS-232C,
RS-485 ) with multi-channel operation that enables easy to connect between DTE and
LinkWiser™-S400M Rev. 2.1 without additional interface circuits. It is all that just plug into power and
connect it to DTE.
LinkWiser™-S400M Rev. 2.1 supports point-to-point, point-to-multi, multi-drop and repeater function in
compliances with most of wire-line based networking solutions such as Profibus, Modbus,
Pelco-D, Pelco-P, etc. and realizes 0% PER (Packet Error Rate) in 800 meters (about half mile) - LOS
(Line of Sight), 14bytes @ 1000 times, 0dBi antenna, 4.8kbps air rate - at max. 10mW (+10dBm)
output power.
LinkWiser™-S400M Rev. 2.1 is ideally suitable where higher reliability and performance is required.
LinkWiser™-S400M Rev. 2.1 is ideally suitable with South Korean KCC & Japanese ARIB regulations.
And it supports 400~470MHz frequency band at 12.5KHz of narrowband operation.
LinkWiser-S400M Rev. 2.1 is approved by South Korean Authority in conjunction with
LARN2-IO2S424.7125/424.9500TR0.01F1D22220 (데이터전송용, 424MHz, 20ch),
447.8625/447.9875TR0.01F1D11 (데이타전송용, 447MHz, 11ch) and
LARN3-IO447.2625/447.5625TR0.01F1D25 (안전시스템용, 447MHz, 25ch). And KCC ID is
“CE3-LinkWiserS400M.
