PCIe X4 host card - 1 x standard PCI slot bracket for host adapter 2U

The ALLDAQ ADQ-63 is an I2C multiplexer, buffer, isolator and level shifter I2C Multiplexer: The I2C "master channel" at the input can be designed as a standard I2C or as an ADQ link. This addresses a multiplexer module. This I2C or ADQ-Link bus is then extended to up to 3 additional channels. The multiplexer has 8 switchable I2C addresses, so that other boxes can be used simultaneously around several slaves with identical I2C addresses. I2C Extension: In addition to the conventional I2C bus as output, the ADQ-I2C modules also offer specially buffered interfaces - the ADQ-LINK. This allows 2 boxes to be used as an extension to cover long distances of several 100 meters via a 2-wire twisted pair cable. At the end a conventional I2C can be picked up again. See also the ADQ-63 or ADQ-151/-63 kit. I2C Isolator: The buffered SCL/SDA lines are capacitively isolated to provide protection against ground loops, for example in case of different GND reference of the end devices on long lines. I2C Level Shifter: The internal pull-ups at 5V can be switched off by software. Thus, external pull-ups can be used to work with other voltage levels Note: The power supply can be provided via any interface. The supply cable must be max. 2m.

ALLDAQ I2C multiplexer, buffer, isolator, level shifter With the I2C multiplexer boxes from ALLDAQ you have numerous possibilities to expand your I2C structures and make them more run-sensitive. I2C Multiplexer: An I2C master channel is generated via USB, which is directly available and additionally addresses an integrated multiplexer module. This I2C bus is then extended to up to 3 additional channels. The multiplexer has 8 switchable I2C addresses, so that other boxes can be used simultaneously and several slaves with identical I2C addresses can be used. I2C Verlängerung: In addition to the conventional I2C bus, the ADQ-I2C modules also offer specially buffered interfaces. Thus, 2 boxes can be used as an extension to cover distances of several 100 meters over a 2-wire twisted pair cable. I2C Isolator: The buffered SCL/SDA lines are capacitively isolated to provide protection against ground loops, for example, if the GND reference of the terminals differs such as when using long cables. I2C Level-Shifter: The internal pull-ups at 5V can be switched off by software. Thus, external pull-ups can also be used to work with other voltage levels
