PROJECT DESCRIPTION CSM-400UE is a modular 410-475MHz RF transceiver designed to provide the RF interface for Hetronic devices. The module is designed to be mounted onto Hetronic coder and decoder boards to convert digital information to RF signals and RF signals to digital information. CSM-400UE can be programmed to function in several different operating modes. Configuring the operating mode and functional settings of each mode allows CSM-400UE to be expandable to additional operating modes, new RF protocols and many frequency channels. CSM-400UE communicates with a PC using the CSM-CFG board as an USB and RS-232 adapter. CSM-400UE uses an internal 3.1V regulator and requires a 3.3-5.0V external power supply. Absolute maximum survival supply voltage is limited to 12VDC. In applications, this will be provided by the host coder/decoder board. CSM-400UE can be configured to operate on any 6.25kHz channel from 410MHz 475MHz. The RF output power is set to 10dBm (10mW). Depending on the protocol, CSM-400UE can operate at RF baudrates up to 50kbps. CSM-400UE is built around the TI CC1200 Sub-1GHz RF transceiver. RF front-end circuitry on the device limits effective performance to ~385MHz to ~500MHz, although the hard frequency limits for the 400 MHz range are from 410 to 475 MHz. RF sensitivity varies depending on the protocol being used. All of the functionality of the CSM-400UE is configured in the firmware. CSM-CFG is also used to load the firmware bootloader over RS-232 and firmware application using the USB Flash Programmer tool. CSM400UE can also connect to the PC H-Link tool over the CSM-CFG board. H-Link serves an important purpose for CSM-400UE: calibrating the on-board radio. Every CSM-400UE module must be calibrated before use in a Hetronic product. H-Link calibration compensates for production variation in the RF performance of the on-board radio. CSM-400UE by default is configured to 'ELP-TRx' mode. This causes it to act as a transceiver for the Hetronic ELP protocol. In this mode it will only communicate with other ELP devices. In ELP Mode, radio control and data transfer are all handled over the DI and DO pins with 115.2k baud UART. The legacy 'AF' pin does not support audio output but is instead used for USB detection. CSM-400UE's frequency and encryption can be configured using the CSM Configuration Tool. For more information, see the CSM_CFG Technical Document.

FUNCTIONAL DESCRIPTION 6.1. Configuration CSM-400UE is configured by the CSM Configuration Tool software. For more information on this tool, see the CSM_CFG Tech Doc. 6.2. ELP Mode In ELP Mode, the CSM-400UE acts as an ELP Transceiver. ELP is the Hetronic 'Event Link Protocol', which operates at 50kbps baudrate, 4GFSK modulation and 6.25kHz deviation. In this mode the radio can only be controlled and used with an ELP coder/decoder. Default output power is set to 0dBm but can be configured to +/-10dBm. In ELP Mode, the device is centered on a 12.5kHz channel, between 410MHz and 475MHz. In ELP Mode, CSM-400UE will only communicate with other radios using ELP. ELP Mode also allows the CSM-400UE to enable/disable encryption of the wireless data. Encryption-enabled and -disabled devices cannot communicate with each other. 6.3. Test Mode In Test Mode, the CSM-400UE will function in one of several configurable Test Modes: 6.3.1. CW Test Mode In CW Test Mode, the CSM-400UE will continually output a single-frequency tone for test measurement purposes. The frequency and peak output power of the CW tone are configurable. 6.3.2. ELP Random Transmit Mode In ELP Random Transmit mode, the CSM-400UE will continually transmit a random string of data at the ELP settings: 50kbps, 4GFSK modulation with a 6.25kHz deviation. 6.3.3. ELP Random Receive Mode In ELP Random Receive Mode, the CSM-400UE will continually receive any data broadcasted with the ELP settings in the ELP packet structure.

On the Verification successful window click OK. 9. Close the USBFP software. Remove the USB cable from the CSM_CFG. 9.5. Calibration After programming, each CSM-400UE must be calibrated at least once prior to operation. This calibration is to compensate for small variations in RF characteristics due to component tolerances. 9.5.1. Output Power Calibration The output power of the module varies across its frequency range; this calibration procedure applies an internal offset to the output power depending on frequency to compensate for that variation: 1. Insert CSM-400UE into CSM_CFG and connect the USB cable. Connect CSM-400UE ANT to a calibrated Spectrum Analyzer using low-loss cable. 2. Close the J_US jumper, then J_VBUS. Insert the H-Link dongle into the PC. 3. Start the H-Link software. Press "Connect". This should load the CSM-400UE H-Link configuration menu. Go to the 'Calibration' tab. Revision Research and Development Technical Documentation Form Rev. A Project: Description: Page RF Transceiver module / Sub 1GHz 15 of 27 4. If the module has not yet been calibrated, a 'WARNING: Device not calibrated!' will be displayed. If the module has been calibrated, H-Link will show the date of the last calibration. Click 'Begin Calibration'. 5. Follow the instructions listed to configure the Spectrum Analyzer to 150MHz bandwidth centered at 450MHz. You should see a peak at 390MHz. Use the Peak Search function to find the peak power at 390MHz. Revision Research and Development Technical Documentation Form Rev. A Project: Description: Page RF Transceiver module / Sub 1GHz 16 of 27 6. Use the "+" and "-" Coarse Adjust buttons to increase or decrease the peak power at 390MHz. Continue adjusting the power until it is with +/- 0.3dB of 0dBm. 7. When the peak is within +/-0.3dBm, click 'Save and Continue', then click 'Yes' when prompted 'are you sure?'. This will move the peak frequency to 395MHz. 8. Repeat Step 6 and 7 for 395MHz, and each incremental frequency after that. The frequency will continue to increment by 5MHz up to 475MHz. After the 475MHz peak is calibrated, click 'Save and Continue' to continue to Frequency Calibration. Revision Research and Development Technical Documentation Form Rev. A Project: Description: Page RF Transceiver module / Sub 1GHz 17 of 27 9.5.2. Frequency Calibration This procedure fine-tunes the frequency setting of the module by applying a constant offset to the Frequency Synthesizer. 1. Follow the instructions displayed to configure the Spectrum Analyzer: set Center Frequency to 450MHz, Span to 100kHz, Resolution BW to 100Hz and Video BW to 30Hz. This should show the frequency synthesizer error more precisely. 2. Use the "+" and "-" Coarse Adjust buttons to increase/decrease the frequency from the module until it is approximately centered at 450MHz. Revision Research and Development Technical Documentation Form Rev. A Project: Description: Page RF Transceiver module / Sub 1GHz 18 of 27 3. Configure the Spectrum Analyzer span to 10kHz to see the frequency error more precisely. Use the "+" and "-" Fine Adjust buttons to increase/decrease the frequency from the module until it is exactly 450MHz. 4. When finished, press 'Save and Continue'. 9.5.3. RSSI Calibration The CSM-400UE has a built-in power detector capability. This calibration sets the reference level so the power detector can return received RF power in dBm: 1. Connect the output of the RF Signal Generator to the antenna port of the radio module using a low-loss cable. Configure the Signal Generator to output 450.000000MHz, no modulation, at a power of exactly -60dBm. Revision Research and Development Technical Documentation Form Rev. A Project: Description: Page RF Transceiver module / Sub 1GHz 19 of 27 2. The PC should display what the current un-calibrated power measurement is as "RSSI = [x]dBm". Use the "+" and "-" Coarse Adjust buttons to adjust the measured power level until it reads "-60dBm". 3. When finished, press 'Save and Continue'. Device Calibration is now complete. Before disconnecting the module, go to the 'Transfer' drop-down on the top bar and select 'Save Settings to Device'. Click 'Yes' when asked if user is sure, and wait for the settings to fully download. 4. When settings are finished downloading, close H-Link, open the J_US and J_VBUS jumpers before removing the module. Revision Research and Development Technical Documentation Form Rev.
