The maximum cable length supported by the ST232ACW is approximately 50 feet (15 meters) at a baud rate of 9600bps. However, this can vary depending on the cable quality, noise environment, and baud rate.
The ST232ACW supports hardware flow control using RTS/CTS signals. You can enable flow control by connecting the RTS (Request to Send) pin to the CTS (Clear to Send) pin of the receiving device. You can also use software flow control using XON/XOFF characters.
The power consumption of the ST232ACW depends on the operating mode and supply voltage. In normal operation, the typical supply current is around 5mA at 5V supply voltage. In low-power mode, the supply current can be as low as 0.5mA.
Yes, the ST232ACW is compatible with 3.3V systems. The device can operate with a supply voltage range of 2.7V to 5.5V. However, ensure that the input signals are within the recommended voltage range to avoid damage to the device.
To configure the ST232ACW for 9-bit data transmission, you need to set the M0 and M1 pins accordingly. For 9-bit data transmission, set M0 = 1 and M1 = 0. Additionally, ensure that the transmitter and receiver are configured to use 9-bit data transmission.
