Introduction

Signalyzer H series products are multi protocol USB host adapters which are capable of emulating most popular serial protocols such as SPI, I2C, JTAG and SWD. It allows a developer to interface a Windows, Mac OS or Linux PC to an embedded system via USB and provide a developer an access to a serial bus and target devices it connects.

Signalyzer H4 provides access to 4 independent channels located on two Signalyzer H4 ports. Both Signalyzer H2 ports utilize same 26pin IDC header with 0.1” pitch.

Notes: (1) For correct I2C operation both SDA signals (pins 4 and 5) must be tied together.

                                (2) For correct SWD operation both SWDIO signals (pins 4 and 5) must be tied together.

Port B

Notes: (1) For correct I2C operation both SDA signals (pins 4 and 5) must be tied together.
