Overview

The RM024 RAMP module is based on Laird's LT2510 core technology, enhanced with a new RF front end for improved sleep, improved link budget and a switchable antenna output. With its field-proven FHSS air interface protocol, the RM024 rejects RF noise, excels in multipath scenarios, allows for co-located systems, and provides an extremely reliable communication link. It also provides a more robust, but simpler, link than ZigBee for RF applications that do not require a mesh topology.

Note: Some variants of the RM024 and related DVK and SDK variants have reached end of production and are available on a limited basis only. Please review the June 2019 End of Life Announcement.

FAQ

How many volts does the RM024 need in order to operate?

3.6 volts

I am not getting the expected range from a U.FL-only RM024. Why?

Product ID’s containing an “M” (RM024-S125-M-01, RM024-P125-M-01, RM024-S50-M-01, and RM024-P50-M-01) have both chip and U.FL antennas on board. However, products containing a C (RM024-S125-C-01, RM024-P125-C-01, RM024-S50-C-01 and RM024-P50-C-01) only have the U.FL on board. When you select chip antenna on a C product, there is no RF link. This feature does not work in FW v1.3-0 on 50 mW radios (RM024-x50-C-01). Antenna Switch (EEPROM 0xC1, bit 5) selects either integrated chip antenna or U.FL connector for external antenna.

Note: On RM024 –C units with no integrated antenna, the RF switch is still active and it is possible, though not advised, to switch to the integrated antenna option even though there is no antenna connected. RF performance in this configuration would be degraded. See Antenna Select Override in the RM024 User Guide for additional options.

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

 

What does the “Disable Drivers” header on the RM024 DVK do and what is it used for?

The Disable Drivers jumper pins disable the RS232 drivers by creating a buffer between the RS232 and the radio. This will then allow you to pipe your own signals into the radio. If you do not disable the drivers, then you would have outputs from the buffer as well as your device. Therefore, both outputs would be trying to drive the same signal.

Why is my RM024 client module pulling an average of 35-40mA when the server is not powered on but drops to around 10mA when I turn the server on?

The RM024 client sits in a receive mode when not synchronized to a server that matches its system ID and RF channel. This can happen when a server is either not powered on or out-of-range of the client. This "unsynchronized" receive mode will pull an average of 35-40mA depending on other settings within the client radio. In this mode, the client radio's receiver circuitry is constantly ON and the radio performs a "slow hop" scan of all frequency bins within its pseudo-random hop sequence (determined by RF channel); this is done while the radio waits for a server beacon to synchronize with that matches its system ID and RF channel settings. After the RM024 client synchronizes to a server, the average current will drop to 10mA because the client can enter idle mode when the radio is not active (RF_RX or RF_TX). When synchronized the client and server have the same hop frame timing and setup so the client knows when to enter receive mode to retrieve the beacon from the server and when to enter receive mode to look for data in each data slot.
