Rs 232 - Getting started
Arduino library
To test the Arduino, you can use the SoftwareSerial/HardwareSerial librarys which dont need to be downloaded since they are built into the device. Since the device requires no additional coding, this example is enough to showcase it.

Connections
Below is an example connection diagram for Dasduino CONNECTPLUS and the RS-232 Transceiver Breakout Board. These pins will be used in the examples throughout this documentation.
| Dasduino CONNECTPLUS | RS-232 Breakout Board |
|---|---|
| IO13 (TX) (user choice) | DIN1 (TTL Transmit) |
| IO14 (RX) (user choice) | ROUT1 (TTL Receive) |
| 5V | 5V |
| GND | GND |
ℹ️
If you prefer, you can use a second RS-232 channel for additional communication:
| Dasduino CONNECTPLUS | RS-232 Breakout Board |
|---|---|
| IO27 (TX) (user choice) | DIN2 (TTL Transmit) |
| IO26 (RX) (user choice) | ROUT2 (TTL Receive) |
| 5V | 5V |
| GND | GND |
