FORENEX FR-DTE R232 Breakout Board Installation Guide

FORENEX FR-DTE R232 Breakout Board

Product Information

The FR-DTE (RS232) Breakout Board is a device that converts UART-TTL logical level to RS232. It features a UART-TTL with 3.3V/5V tolerance input and RS232 that provides 3-wire or 5-wire mode. The device is RoHS compliant and comes in two ordering options: FR-DTE-W (with wire-to-board connector) and FR-DTE-D (with board-to-board header). The device also comes with a 6-pin to 6-pin wire cable for input, L=150mm (WC7067060153).

Product Usage Instructions

1. Connect the power input (3.3V/5V) to Pin 1 (P) of the UART-TTL connector.
2. Connect the UART-TX (transmit) of your device to Pin 2 (I) of the UART-TTL connector.
3. Connect the UART-RX (receive) of your device to Pin 3 (O) of the UART-TTL connector.
4. Connect the ground (GND) of your device to Pin 4 (P) of the UART-TTL connector.
5. If you are using the 5-wire mode, connect the UART-RTS (ready to send) of your device to Pin 5 (I) of the UART-TTL connector, and connect the UART-CTS (clear to send) of your device to Pin 6 (O) of the UART-TTL connector.
6. If you are using the 3-wire mode, connect Pin 5 (I) and Pin 6 (O) of the UART-TTL connector to NC (no connection).
7. If you are using FR-DTE-W, connect the DTE-RXi (receive input) of your device to Pin 2 (I) of the board-to-board connector, and connect the DTE-RTSo (ready to send output) of your device to Pin 7 (O) of the board-to-board connector. Connect the DTE-TXo (transmit output) of your device to Pin 3 (O) of the board-to-board connector, and connect the DTE-CTSi (clear to send input) of your device to Pin 8 (I) of the board-to-board connector.
8. If you are using FR-DTE-D, connect the pins according to your board-to-board header.
