Bitmerse WS-UT-EN WiSer Host-to-Client Wireless UART Kit

The WiSer Kit is designed for plug-and-play operation. First, connect the WiSer-USB device to your PC's USB port. Next, power the WiSer-TTL device using the provided USB cable and connect its TTL pins (TX, RX, GND) to your target microcontroller using the jumper wires. The devices will automatically pair and establish a secure wireless serial link, requiring no driver installation or software configuration on standard operating systems.

While the exact range can vary based on the operating environment, the WiSer Kit utilizes a robust proprietary RF protocol designed for reliable indoor communication over typical development lab distances. For optimal performance, ensure a relatively clear line of sight between the WiSer-USB and WiSer-TTL units. Obstacles like walls and metal enclosures may reduce the effective range, so position the devices accordingly for critical debugging sessions.

No, the WiSer-TTL device is not designed to provide power to external boards. Its USB power cable is solely for supplying power to the WiSer-TTL unit itself. You must provide independent power to your target microcontroller or development board according to its specifications. Remember to connect the ground (GND) pins between the WiSer-TTL and your target to establish a common reference, despite the kit's signal-level electrical isolation.

The WiSer Kit automatically handles the wireless link, so you configure the baud rate entirely within your serial terminal software on the PC side (e.g., PuTTY, Arduino IDE Serial Monitor) and within the firmware of your target device. Set both ends to the same standard baud rate (e.g., 9600, 115200). The wireless bridge will transparently pass the serial data. There is no need for AT commands or specific configuration of the WiSer devices themselves for basic UART operation.
