LT1110 Series

Recommended for New Design (RND)


Laird's third generation 915 MHz FHSS module sets yet another standard for industrial RF communication. Based on proprietary FlexRF technology, this globally-accepted module will exceed most OEM application and performance requirements. Embedded with Laird's robust server-client protocol, the LT1110 permits an unlimited number of clients to synchronize to a single server for low latency communications. The server and all clients in a network can communicate with any radio in range via either addressed or broadcast packets. The configuration and test software allows OEMs to design and test networks to suit their applications. The enhanced API commands provide packet routing control and network intelligence. With its field-proven proprietary FHSS RF protocol and increased penetration at 915 MHz, the LT1110 rejects RF noise, excels in multipath scenarios, allows for co-located systems, and provides an extremely reliable communication link.

Can I get true full duplex operation from the RAMP products (RM024, AC4490, AC4790, LT1110, CL4490, CL4790)?

In the Laird RAMP line of products there is a feature called Full Duplex that leads one to believe they can talk upstream and downstream simultaneously. This is not the case, Full Duplex in the RAMP products gives a dedicated slot within the frame to the Server or Initiator and the second slot or next frame to the Client or Responder. 

Can I choose an RF Channel that is outside of Wi-Fi interference on the RAMP radios?

The RF Channel setting in our Laird RAMP modules and radios is not a true RF Channel or frequency of operation, it is actually just specifying a psuedo-random hopping sequence. The radios must, per the FCC, hop through every frequency in the band.
The RF Channel setting is only choosing a hopping pattern for navigating through all of the channels but each channel will be hopped to within a single pattern.

Do any of the RAMP products support XON-XOFF?

Xon-Xoff is not supported on any of our RAMP products. Flow control (handshaking) uses hardware RTS and CTS.
