Product details
Overview
STEVAL-CBL001V1 from STMicroelectronics is a ready-to-use demonstration board for programming and functional testing of ST7LNBx microcontrollers used in satellite LNB (Low-Noise Block downconverter) power supply and DiSEqC control systems. It supports on-socket EEPROM programming, coaxial-cable-based remote DiSEqC command transmission (75 Ω), and real-time reply evaluation via dedicated voltage regulation and pre-programmed firmware.
For engineers reviewing the STEVAL-CBL001V1 datasheet, STEVAL-CBL001V1 pinout, STEVAL-CBL001V1 application, or STEVAL-CBL001V1 equivalent, this board enables rapid validation of ST7LNBx device behavior in DiSEqC 1.0/1.1/2.0 command sets, LNB bias voltage sequencing, and serial interface interoperability with Windows HyperTerminal or ST's proprietary GUI application.
Technical Context
The board implements a complete DiSEqC physical layer interface using discrete level-shifting and current-source circuitry compliant with EN 50494 and IEC 61883 standards. It integrates a dedicated linear regulator to generate stable 13/18 V LNB supply rails with overcurrent protection and polarity switching under microcontroller control.
Communication occurs over RS-232 (via COMx port) to host PC, where commands are parsed and translated into DiSEqC-compliant Manchester-encoded bursts (22 kHz carrier, 1.5–2.0 ms pulse width, 50% duty cycle) sent through coaxial output (DTX) and monitored via coaxial input (DRX).
Key Specifications

| Coaxial I/O | 75 Ω impedance-matched DTX (output) and DRX (input) ports supporting bidirectional DiSEqC signaling |
| Microcontroller Socket | 16-pin Berg-stick socket compatible with ST7LNB0 and ST7LNB1 in SO-16 package |
| Software Interface | Windows HyperTerminal-compatible ASCII command set and ST-provided GUI application for Windows 2000/XP |

FAQ
Is STEVAL-CBL001V1 compatible with modern Windows operating systems?
No. The official ST7LNB GUI application was validated only for Windows 2000 and XP. While basic RS-232 ASCII command operation may function under Windows 10/11 via terminal emulators, driver compatibility, timing-critical DiSEqC burst generation, and GUI functionality are not supported beyond XP. Users must rely on HyperTerminal-equivalent tools and manual command framing.
Can STEVAL-CBL001V1 program ST7LNBx devices in-circuit without socket removal?
No. The board provides only a 16-pin Berg-stick socket for standalone device programming and testing. It does not support in-system programming (ISP) or JTAG/SWD debug interfaces. Device programming requires physical insertion into the socket; no trace-level or PCB-mounted LNB controller programming capability is implemented.
What DiSEqC command responses can be evaluated using this board?
The board evaluates DiSEqC reply pulses (ACK/NACK) received on the DRX line, including valid frame detection, Manchester decoding, and basic error flagging (e.g., timeout, invalid checksum). It does not perform full protocol stack analysis or store reply payloads-feedback is limited to pass/fail status and raw pulse timing visible in the GUI or terminal log.
Does STEVAL-CBL001V1 support 22 kHz tone-only operation without DiSEqC data?
Yes. The board generates a clean 22 kHz continuous carrier tone on DTX when configured for "tone burst" mode, independent of DiSEqC packet transmission. This enables verification of LNB switching between vertical/horizontal polarization and universal LNB band selection without sending command frames.
