I. Product Introduction
1. This product is a cross-communication function product. Function: The sender collects 4-channel switch signal and
transmits the data to the receiver through wireless (LoRa spread spectrum) or network port, and the receiver restores the
4-channel switch signal.
2. Product model K61-Dxx, including sending (collection) end: K61D-40Rxx; receiving (output) end: K61D-04Rxx. (For
more naming details, see the "Product Model Naming" chapter)
Figure 1-1
3. The module also has 485 data transparent transmission function. The 485 data of the sender and receiver can be
transparently transmitted through LoRa wireless communication.
4. The product has a high degree of ease of use, avoids long-distance wiring, greatly reduces the cost of
manpower/material resources, and reduces the difficulty of construction and maintenance.
5. Aimed at industrial users, all-industrial-grade design, after a lot of testing, the quality is stable and reliable.
6. Construction-free installation: It can replace the link cable, and the transmission distance is long, eliminating the
trouble of cable construction.
7. Programming-free design: no programming is required, all parameters can be configured through the host computer
software, which is easy to use and reliable in operation.
8. Automatic error correction: The terminal has strong error correction ability and can actively correct the disturbed data
packets, greatly improving the transmission reliability.
1.1 Features
The sending (collection) end supports 4-channel digital signal input;
The receiving (output) end supports 4-way digital signal output;
It has the function of transparent data transmission between the first communication interface (RS485
(default)/RS232) and the second communication interface (LoRa/ETH network port...);
With hardware watchdog, it has high reliability and recoverability;
It has good protection functions such as overcurrent, overvoltage, anti-reverse connection, and anti-misconnection;
Rich indicator lights, comprehensive view of the status, easy to troubleshoot;
The device has a debounce time of 25ms, which makes the input acquisition signal more stable and reliable and less
