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.
The RM024 RAMP module improves upon Laird’s 2.4 GHz RAMP predecessors by lowering power consumption
through the use of three different sleep mode options, an improved link budget, the ability for close proximity
operation at low power, and the inclusion of a switchable antenna output (RM024-xxxx-M-yy versions only).
The RM024 is available in two versions:
RM024-S125-x-xx/RM024-P125-x-xx –Contains 125 mW maximum conducted output power which is
approved for North American and similar markets.
RM024-S10-x-xx/RM024-P10-x-xx –Contains 10 mW maximum conducted output power which is
approved for European and similar markets.
These modules are identical except for output power, transmit power consumption, and the number of RF
channels available. Differences between the two versions, where applicable, are denoted based on part number.
This document contains information about the hardware and software interface between a Laird RM024
transceiver and an OEM host. Information includes the theory of operation, specifications, interface definitions,
and mechanical drawings.
Note: Unless mentioned specifically by name, the RM024 modules are referred to as module, radio, or
transceiver. Individual naming is used to differentiate product specific features. The host
(PC/microcontroller/any device to which the RM024 module is connected) is referred to as OEM
host or host.

RF Hop Frame
The RM024 hops every 13.19 milliseconds and can be configured for two different RF data rates to provide
options for range or throughput. During each hop, the RM024 reserves a certain amount of time for overhead
such as the synchronization beacon, internal messaging, and user data transmission. The diagrams below outline
the various transmissions that occur during a hop. These transmissions are transparent to the user sending data,
but may be useful for applications that require critical timing. User data is only transmitted during the data slots
and after the Interface Timeout or RF Packet Size criteria has been met. Data transmission only begins at the
beginning of a data slot. When configured for Full Duplex, data slot 1 is reserved for the server and data slot 2 is
shared by all clients for transmissions.

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 volt 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.
Force 9600 /Sleep Interrupt
When pulled logic Low before applying power or resetting, the transceiver’s serial interface is forced to 9600,
8-N-1 (8 data bits, no parity, 1 stop bit) regardless of the actual EEPROM setting. RTS is ignored, the interface
timeout is also set to three milliseconds, and the RF packet size is set to the default size for the selected RF data
rate. To exit, the transceiver must be reset or power-cycled with the test pin logic High or disconnected. When
in Force 9600 mode, the radio’s receiver is disabled.
When enabled in the EEPROM, the 9600 Boot option causes the 9600 pin to be ignored on cold boot (power-up),
command boot (0xCC 0xFF), and brown-out conditions. Therefore, the 9600 pin is only observed on warm boots
(reset pin toggled). This can be helpful so that brown-out conditions don’t cause the baud rate to change if the
9600 pin happens to be low at the time. When 9600 Boot option is disabled, the 9600 pin is used for all boot
conditions. 9600 Boot option is enabled by default.
Force 9600 is also used to wake the radio from sleep. When the pin is taken low, the radio wakes. The
transceiver does not sleep if the pin is low when the sleep command is issued.
Note: Because this pin disables some modes of operation, it should not be permanently pulled Low during
normal operation.
µP_RESET
µP_Reset provides a direct connection to the reset pin on the RM024 microprocessor and is used to force a hard
reset. For a valid reset, reset must be asserted Low for an absolute minimum of 250 nanoseconds (ns).
Command/Data
When logic High, the transceiver interprets incoming serial data as transmit data to be sent to other
transceivers. When logic Low, the transceiver interprets incoming serial data as command data. When logic Low,
data packets from the radio are not transmitted over the RF interface, however, incoming packets from other
radios are still received. Enabling CMD/Data RX Disable in the EEPROM causes incoming RF packets to be queued
by the receiving radio while CMD/Data is low. When CMD/Data goes high, the data is sent over the serial
interface.
In_Range
The In_Range pin is driven low when a client radio’s frequency hopping is synchronized with that of a server.
In_Range is always driven low on a server. Following boot, In_Range transitions low in approximately 12
milliseconds on a server. For a client, the In_Range takes an average of 500 milliseconds; this time 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 milliseconds to over 1500 milliseconds.
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. The OEM host is not required to monitor hop frame.
RTS and Handshaking
With RTS mode disabled, the transceiver sends any received data to the OEM host as soon as it is received.
However, some OEM hosts are not able to accept data from the transceiver at all times. With RTS enabled in
EEPROM, the OEM host can prevent the transceiver from sending data by de-asserting RTS (High). Once RTS is
re-asserted (Low), the transceiver sends packets to the OEM host as they are received.
Note: Leaving RTS de-asserted for too long can cause data loss once the transceiver’s transmit buffer
reaches capacity.
CTS Handshaking
If the transceiver buffer fills up and more bytes are sent to it before the buffer can be emptied, data loss occurs.
The transceiver prevents this loss by de-asserting CTS high as the buffer fills up and asserting CTS low as the
buffer is emptied. CTS should be monitored by the host device and data flow to the radio should be stopped
when CTS is high.
DE/RE
When enabled, RS485 Data Enable uses the DE/RE pin to control the DE pin on external RS-485 circuitry. When
the transceiver has data to send to the host, it asserts DE/RE High, sends the data to the host, and then takes
DE/RE low.
PWM Output
PWM output can be configured to output on any of three pins (SMT Pins 5, 6, or 7). The PWM Output can
optionally produce a pulse width modulation for RSSI with a period of 39.3846 µS.
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 in the mechanical drawings below (Figure 3 and Figure 4) 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.
Note on Mechanical Drawings:
All dimensions are in millimeters
PC board material is 0.79 mm thick FR4
Provide clearance of at least 1.5 mm around the module to be free of other components and features
Module should not exceed 260˚C during reflow soldering

REFLOW PARAMETERS
Laird’s surface mount modules are designed to be easily manufactured, including reflow soldering to a PCB.
Ultimately, it is the responsibility of the customer to choose the appropriate solder paste and to ensure oven
temperatures during reflow meet the requirements of the solder paste. Laird’s surface-mount modules conform
to J-STD-020D1 standards for reflow temperatures.
IMPORTANT: During reflow, modules should not be above 260°C and not for more than 30 seconds.
Figure 6: Recommended reflow temperature
Temperatures should not exceed the minimums or maximums presented in Figure 6.

Note: The OEM is free to choose another vendor’s antenna of like type and equal or lesser gain as an antenna
appearing in the table and still maintain compliance. Reference FCC Part 15.204(c)(4) for further
information on this topic.
To reduce potential radio interference to other users, the antenna type and gain should be chosen so
that the equivalent isotropically radiated power (EIRP) is not more than that permitted for successful
communication.
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. Reference FCC Part 2.1091 for further details on mobile devices.
Portable –Portable is a classification of equipment where the user, in general, is within 20 cm of the
transmitting antenna. Portable equipment is further broken down into two classes; within 2.5 cm of human
contact and beyond 2.5 cm. The RM024 does not hold a portable approval classification due to its peak
output power and modular approval restrictions. Further RF evaluation is required by customers who want
to use the RM024 in portable applications. Contact a qualified test house or a Laird Technologies
representative for further information on this topic. Reference FCC Part 2.1093 for further details on
portable devices.
A Maximum Permissible Exposure report has been created which shows the minimum distances for Public and
Occupational use of the RM024.
Note: Occupational Limit Minimum Distance = 4 cm
Public Limit Minimum Distance = 9 cm
A full MPE report is available upon request.
OEM Responsibilities
WARNING:The OEM must ensure that FCC labeling requirements are met. This includes a clearly visible label on
