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. 1.1 Key Features Retries and acknowledgements Configurable network parameters Multiple generic I/O 280 kbps or 500 kbps RF data stream Idle current draw of 9.5 mA, sleep current of <1 uA (varies depending on sleep mode) Software-selectable interface baud ranging from 1200 bps to 230.4 kbps Upgradable FW through serial port Low cost, low power, and small size ideal for high volume, portable, and battery powered applications All modules are qualified for Industrial temperatures (-40°C to 85°C) Advanced configuration available using Laird’s Command Interface Easy-to-use Laird Configuration and Test Utility software Switchable antenna output, either integrated antenna or external antenna through U.FL (RM024-S125-M, RM024-P125-M, RM024-S10-M, and RM024-P10-M radios only) Embedded Wireless Solutions Support Center: http://ews-support.lairdtech.com www.lairdtech.com/ramp 5 © Copyright 2015 Laird.

Generic Input Reset – Controlled by the RM024 for power-on reset if left unconnected. After a stable power-on reset, a logic low pulse resets the transceiver. 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. When logic Low, the client is in range and synchronized with a server. This is always Low on a server. Request to Send – Floats high if left unconnected. When enabled in EEPROM, the module will not transmit Serial UART data to the OEM Host unless this pin is Low. Clear to Send – CTS is used for hardware flow control indication to the OEM Host. CTS toggles high when the Serial UART RX input buffer reaches the CTS On threshold and remains high until the buffer recedes below the CTS Off threshold. Generic Input Reserved for future use.

Read Flash 1.8 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.

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. 2.1.2 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.

All Rights Reserved Americas: +1-800-492-2320 Europe: +44-1628-858-940 Hong Kong: +852 2923 0610 RM024 – RAMP Wireless Module Datasheet 2.1.3 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). 2.1.4 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. 2.1.5 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. 2.1.6 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. 2.1.7 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: 2.1.8 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. 2.1.9 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.

The required antenna impedance is 50 ohms. Manufacturer Laird Laird Laird Laird Nearson Manufacturer Part Number WIC2450-A NZH2400-MMCX ID2450-RS36 IG2450-RS36 S151-6-PX-2450S Laird Part Number Type 0600-00042 2150-00006 CAF95990 CAF94722 0600-00040 Chip Microstrip Panel Omni Dipole Gain (dBi) 2 1 9 6 2 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. 6.1.4 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. 6.1.5 OEM Responsibilities WARNING: The OEM must ensure that FCC labeling requirements are met. This includes a clearly visible label on the outside of the OEM enclosure specifying the appropriate Laird FCC identifier for this product as well as the FCC notice below.
