Laird Transitioning from LT2510 to RM024 v1 0 INTRODUCTION The RM024 is the first new module in Laird s rebranded RAMP Range AmplifiED MULTIPOINT LINE OF MODULES Laird s RAMP modules excel at providing a wireless serial link over long ranges and with support for multipoint networks RAMP modules utilize a Frequency Hopping Spread Spectrum FHSS protocol for greater interference and multipath immunity With two transceivers the RAMP line can provide a wireless serial cable replacement capable of extending communications well beyond the 50 foot maximum for wired connections RAMP modules also support multipoint Star network topologies and users can employ a nearly unlimited number of clients for applications such as sensors controls and text display boards The RM024 is based on the same core technology as the LT2510 and is designed to be a drop in replacement Differences between the modules may affect customer designs this document IDENTIFIES THESE differences ThE RM024 AND THE LT2510 ARE OVER THE air Compatible and can both be used in the same network PART NUMBERS PRM110 RM024 S125 C 01 SMT ss 125 mW FL Jack RMO024125CO1 PRM 111 RM024 S125 M 01 eT 125 mW PRM111 s RMO24 S125 M 01 SMT 125mW W ChipAntenna RM024125M01 Antenna RM024125M01 PRM120 RM024 P125 C 01 Pluggable 125 mW u FL Jack RM024125C01 PRM121 RM024 P125 M 01 Pluggable 125 mW Chip Antenna RM024125M01 PRM112 RM024 S50 C 01 SMT 50 mW CE
