CL4790 Series
Overview
ConnexLink stand-alone radio modules are set up in minutes to cut the cables between RS232 or RS485 devices. Their flexibility and economic price allow users to quickly upgrade wired terminals to cordless operation in industrial commercial and residential applications. Powered by a 100mW 2.4GHz radio or a 1000mW 900MHz radio each unit is small and easily portable for use in mobile and temporary settings as well as fixed installations. Optional software enables custom configurations based on user needs. ConnexLink implements a proprietary communication protocol to provide secure local data transmissions. Because it uses FHSS technology the data remains reliable over distances of up to 20 miles (32 km) line-of sight (900MHz version). Use of license-free frequency bands ensures that units are ready to use with no further certification requirements. Every unit is backed by a full one-year warranty. ConnexLink radio modules provide simple elimination of cables with a wireless link replacement.

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.
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.
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.
I have TX API/RX API enabled on my RM024/AC4490/AC4790/CL4490/CL4790 and I'm seeing errors when I run the Range Test, why?
The API features in the RAMP radios allow for dynamically addressing packets (TX API), getting the sender's information when receiving a packet (RX API), and knowing when a packet was successfully transmitted (Send Data Complete). TX API and RX API both append a header to transmitted or received data while Send Data Complete is a separate message that gets sent to the transmitting radio's host when the packet that was transmitted is received successfully at the other end. The Laird Configuration and Test Utility Range Test does not account for these additional headers or packets when 'Create Data' is used in the 'Transmit Packet Selection' field. It will not append headers to the transmitted data so if TX API is enabled all packets for transmission will be tossed because of the lack of a header. It will not account for the additional header that is added to the received packet when RX API is enabled so all packets received will be received as "Data Error". It will not account for the extra packet sent to the transmitting radio's Host when Send Data Complete is enabled so anytime this message is sent it will be seen as a "Data Error". In order to work with the API features on the RAMP radios you should use the scripting feature to write an API script and load it in the 'Transmit Packet Selection' field as 'Load File'.
More information about scripting can be found in Appendix 1 of the Laird Configuration and Test Utility Software - RAMP Modules.pdf
