First part of two, covering the RS-422 specification and performance …
↓↓↓ Complete description, time index and links below ↓↓↓
In the end we will transmit a 10MHz square wave signal over 20m of Cat 3 twisted pair. But before that I’ll give you a little overview about RS-422, differential signaling and what’s on my bench, including the Renesas ISL8490 transceivers I’m using.
That is followed by a dive into the RS-422 specification, and crosschecking the datasheet of the Renesas ISL8490 RS-422 transceiver with it. Finally we turn up the distance (20m) and frequency (10MHz), and I explain why RS-422 works so well.
00:00 Intro – what we’ll have a look at
00:44 Overview – RS-422, ISL8490, differential signaling, nomenclature
06:21 RS-422 specification – and what’s in the Renesas ISL8490 datasheet
19:54 RS-422 performance – speed, distance, noise/interference resilience
28:44 Wrap-up – next we’re using RS-422 with an Arduino MCU, bye
