Dh 485 protocol manual

Our RS-485 is a serial commuication protocol. RS-485 is still the most widely used protocol for POS, industrial, and telecom applications. The wide common-mode range enables data transmission over longer cable lengths and in noisy environments such as the floor of a factory. Reproduction of the contents of this manual, in whole or in part, without written permission of MicroLogix 1400 controllers support various protocols on the RS-485 network, including DH-485 In this section, DH-485 protocol is used as an example. Any physical connection should be the same as DH 485 is a protocol, like Modbus and DF-1 are protocols. RS485 is an electrical specification for the physical layer connections. They are not related or compatible. To be able to communicate with an Allen-Bradley device and a Modbus device you need a protocol converter. Im currently analyzing Dahua's RS485 protocol that is used to interconnect VTO/VTH's and expansions. My goal is, to add a fingerprint from Dahua's security products (ASR1102A) and maybe other stuff. Is there any dahua RS485 protocol (DH-SD?) description available?

Utilizing a series of dedicated interface devices, it RS-485 does not define a communication protocol; merely an electrical interface. Although many applications use RS-485 signal levels, the RS-485 Protocol Manual Revision: 1.0 January 11, 2000 RS-485 Protocol Guidelines and Description Page i Table of Contents 1.0 COMMUNICATIONS BUS OVERVIEW DESIGN GUIDELINES Hardware Design. But what if you need to replace a 550 or 600 legacy DH-485 PanelView? Its still possible, but not nearly as clean and neat a solution. The PanelView Plus 6 400 and 600 still support the DH-485 protocol on it's built-in RS-232 DB9 serial port, so what also is needed is an RS-232 to RS485 converter.
