RS232

RS485 board

RS485 is an alternatve for RS232 for long distances. Maximum length of the cable for RS232 is only 15m. For RS485 it is about 1200m. In addition you can connect many devices to RS485 bus (unlike RS232 — only 2).
Send/receive mode is selected by RTS signal. The converter was designed to be as simple as possible, so it has no some features that can be found in commercial grade products (e.g. galvanic separation).

One of the best methods to visualize ROV data is to show them as overlay on images from camera.
This project can be used in any ROV. It presents data read from sensors mixed with video signal from camera. It can read data from analog 4-20mA sensors and from I²C chips. Although project assume usage of specific sensors, any I²C or 4-20mA sensors can be used. Only software needs small modifications.
