Introduction

A Serializer / Deserializer (SerDes) in usage with onsemi sensors are devices that enable remote connection over a coax cable. The SerDes devices are in pairs, with the Serializer connected to the sensor headboard and the Deserializer connected to a Demo3 and the coax cable between them. The DevSuite Quick Start Guide has additional information on these types of connections.

The remainder of this document will describe the purpose the DevWareX built-in SerDes settings, how the override files work, the location of override examples and how to apply them, how to create a CDAT file to access SerDes registers via the DevWareX Register dialog.

DevWareX Built-In Settings

DevWareX has built-in SerDes settings to enable reading of a sensor’s registers for DevWareX Auto-Detect function to work. These built-in settings are meant mainly for register read/write, but may also sometimes work for data streaming. In most cases, an INI file preset needs to be created with the correct set of sensor and SerDes settings for efficient data streaming.

The following vendors' SerDes have built-in settings:

• Maxim: 96706, 9296, 96716, 96792A, 96793

• TI: 914, 934, 954, 960, 973
