WebJun 27, 2024 · High-level Data Link Control (HDLC) High-level Data Link Control (HDLC) is a group of communication protocols of the data link layer for transmitting data between network points or nodes. Since it is a data link protocol, data is organized into frames. A frame is transmitted via the network to the destination that verifies its … WebMay 27, 2024 · The corresponding pins will depend on your device’s user manual and the RS-485 cable connector type. For NI serial hardware connector pinout diagrams, refer to the Serial Quick Reference Guide. Half Duplex (2-Wire) For 2-wire transmission, you will need to short the transmit (TXD) and receive (RXD) signals together on the RS-485 port.
