Remote
Monitoring Systems Omnex HopLink Simplex Radio Modems
The Omnex HopLink Simplex radio/modems (TEX-900/REX-900
pair) are "cordless wires", reliably replacing cable
and conduit for one-way monitoring or control. With
multiple digital and analog points avaialble on their
terminal blocks, the HopLink Simplex units perform like
wireless bundles giving integrators and panel builders
greater flexibility in system design.
Remote devices, such as switches, alarms and sensors
are wired directly to the terminal block of the TEX-900
HopLink transmitter. The input signals to the TEX-900
are then transmitted to the RX-900 via a Spread Spectrum
Frequency Hopping technique that updates 50 times every
second and guarantees signal integrity with CRC-16 error
checking. At the receiving end of the cordles wire REX-900
HopLink replicates the signals on its terminal block
and outputs them to relays, PLCs, meters, etc. The simple,
reliable wireless link eliminates the expense and maintenance
of cable and conduit.
