RM024 Hardware Integration Guide Version 3.1 RAMP MODULES Laird RAMP (Range Amplified MultiPoint) modules are designed to provide robust wireless communications for any number of applications requiring a wireless transport for serial data. RAMP modules feature a Frequency Hopping Spread Spectrum (FHSS) protocol for excellent interference and multipath immunity. RAMP modules server/client architecture allows for more than 16 million clients to be addressed and communicating within the network.

After a stable power-on reset, a logic Low pulse will reset the transceiver. 15 11 I CMD/Data When logic Low, the transceiver interprets incoming OEM host data as command data. When logic High, the transceiver interprets OEM host data as transmit data. 16 15 O In Range When logic Low, the client is in range and synchronized with a server.

RM024 Hardware Integration Guide Version 3.1 HARDWARE INTERFACE Pin Descriptions RXD and TXD The RM024 accepts 3.3 VDC TTL level asynchronous serial data from the OEM host via the RXD pin. Data is sent from the transceiver, at 3.3 V levels, to the OEM host via the TXD pin. Pins should be left floating or high when not in use. Leaving the RXD tied low results in the radio transmitting garbage serial data across the RF.
RM024 Hardware Integration Guide Version 3.1 is dependent on the signal strength of the received beacon, the presence and strength of interference, and randomness of the sync function. It can vary from 150 ms to over 1500 ms. GO_0/Hop_Frame The Hop Frame indicator functionality is disabled by default and controlled by the Control 1, Bit-6 EEPROM Setting. When enabled, this pin transitions logic Low at the start of a hop and transitions logic High at the completion of a hop.
RM024 Hardware Integration Guide Version 3.1 MECHANICAL CONSIDERATIONS Mechanical Drawing The pluggable versions of the RM024 consist of the surface mount RM024 on a pluggable adapter board. RM024 –C versions, which only feature an U.FL connector and no integrated antenna, are the same dimensions as below with the stub for the antenna connector removed. For the surface mount units, this means the module is 32.38 mm long. For the pluggable units, the module is 33.02 mm long.

RM024 Hardware Integration Guide Version 3.1 Power Exposure Information In general, there are two agency classifications for RF radiation exposure in wireless applications: Mobile – A mobile device is defined as a transmitting device designed to be used in such a way that a separation distance of at least 20 centimeters is normally maintained between the transmitter's radiating structures and the body of the user or nearby persons. The RM024 is fully modular approved for mobile and fixed applications.
RM024 Hardware Integration Guide Version 3.1 WARNING: This equipment has been approved for mobile applications where the equipment should be used at distances greater than 20 cm from the human body. Operation at distances of less than 20 cm requires additional RF exposure evaluation and possible testing, including SAR requirement according to FCC RF Exposure guideline. CAUTION: Any changes or modifications not expressly approved by Laird Technology could void the user’s authority to operate the equipment.
