Overview

Introduction

USB TO 8CH TTL, an industrial UART TO 8CH TTL converter with an aluminum alloy case, features the original CH348L chip and built-in protection circuits such as the self-recovery fuse and TVS. This converter is easier to operate due to its fully automatic transceiver circuit with no delay. Boasting characteristics of fast communication, stability, reliability, and safety, it is an ideal choice for various industrial control devices and applications with high communication requirements.

Features

  • Extending USB to 8CH TTL (UART) with hardware flow control, allows concurrent and independent communication for each channel.
  • Onboard resettable fuse and protection diodes, ensure the current/voltage stable outputs, provide over-current/over-voltage proof, improving shockproof performance.
  • Onboard TVS (Transient Voltage Suppressor), effectively suppresses surge voltage and transient spike voltage in the circuit, lightningproof & anti-electrostatic.
  • Onboard voltage translator circuit, with anti-surge and ESD protection, safe and stable communication.
  • Onboard TTL serial 3.3V/5V voltage translator, config the TTL level via the switch.
  • Aluminium alloy enclosure with oxidation dull-polish surface, CNC process opening, solid and durable, well-crafted.
  • 4x external LEDs for indicating the power and transceiver status.

Communication Operation

  • Open SSCOM software.
  • In general, the identification of 8 COM port numbers usually proceeds sequentially from Port A to Port H, starting from the smallest.

TTL Communication

The following displays how to perform the communication between the UART 0 and UART 1 of the product.

Hardware Connection

USB TO 8CH TTL - UART 0 USB TO 8CH TTL - UART 1
UART 0 - TXD UART 1 - RXD
UART 0 - RXD UART 1 - TXD
UART 0 - GND UART 1 - GND

Software Operation

  • Open two SSCOM interfaces.
  • Select the corresponding COM port of the UART0 and UART 1, respectively.

FAQ

 Answer:
The interface of this product takes 2*3PIN as a group of serial ports, and circulates to the right in order. There are 8 groups of serial ports in total. The color corresponding to each interface is the color corresponding to the 50PIN wire after it is connected to the wire. The specific distinction is shown in the figure:

 Answer:
  • Generally, USB power supply is enough, and for old computers with insufficient USB power supply, DC power supply can be used.
  • If multiple channels are used at the same time, multiple devices are connected at the same time, the communication distance is relatively long, the bandwidth can not be loaded, it is necessary to use; TTL power consumption is relatively low.

 Answer:

This product has a level conversion chip on board, and there is a data conversion rate when using, so please try to avoid too much data conversion in the middle of the communication.
