Serial To Usb Chip

PL2303TA New Product Announcement

Now the USB port reigns supreme! But USB is hard, and you just want to transfer your every-day serial data from a microcontroller to computer. Enter the Adafruit CP2104 Friend! This is a high-quality CP2104 USB-Serial chip that can upload code at a blistering 2Mbit/s for fast development time. Ans: USB-Serial devices support LVTTL IO levels for Inputs only. CMOS IO level is supported for both Inputs and Outputs. Do USB-Serial devices require external 1.5K pull up resistor on USBDP line? Ans: No, USB-Serial devices don't require external 1.5K pull up resistor on USBDP line. The pull-up resistor is integrated inside the chip. Prolific (PL2303) adapter is an common solution about USB to Serial port adapters. Even so the company gives their chips only to branded companies. And the latest Prolific driver, it does one identity recognition at the hardware too. If the Prolific chip in your adapter is a fake copy, the driver does not work with it.

How to migrate from PL-2303HXA/XA PCB to PL2303TA chip

ComTestSerial
Free serial communications test program

Download ComTestSerial for free, use it and give it to anyone who has a need for a serial communications test program!

MicroRidge manufactures a variety of serial interface devices. We had a need for a fast, effective and easy-to-use serial test communications program. We developed ComTestSerial to meet that need, and are offering it free of charge to anyone who has a need for a test program to help them understand the output of their serial device.

Usb Interface Chip

Why do you need ComTestSerial?
When you cannot get communications between your serial device and your application, you typically need to perform the following troubleshooting steps. These steps are general troubleshooting guidelines. Our experience has shown us that you can save hours and even days worth of troubleshooting if you first get an understanding of the operation of your serial device using a test program such as ComTestSerial.

1. Connect your serial device to a serial communications test program such as ComTestSerial.

2. Press the send button on your serial device to send information to ComTestSerial or send a command from ComTestSerial to your serial device.

3. Find the manual for your serial device to determine what the baud rate and communications parameters should be (yes, I know we all hate to read the manual!).

4. If you have multiple serial ports on your PC, change the serial port within ComTestSerial to determine which serial port your device is connected to.

5. Refer to the Help Troubleshooting Section in ComTestSerial for additional suggestions.
