Product Description
5CELEC 12 Ways Switch DC Signal To RS 485 232 TTL Serial Port Output Converter Receiver Module RX-750 |
Features 1, RX-750 Switch value signal to RS-485 serial port converter receiver module is used for receiving wired or wireless switch value signal input and converse to RS-485/232/TTL serial port output. 2, The module is widely applied to communicate between security system front end detectors/sensors and data center servers. 3, The module can be used directly when input wired signals without matching operations. 4, The module accept RF433MHZ wireless receiving, multi nodes communication, RS-232,TTL etc. customization.
Connection instructions1,Wired power supply to 'POWER + -'. 2,Waiting D2 indicator continuedly flash. 3,Connect the front end detectors/ sensors to 'INPUT 'ports. 4,Connect the module to data center server via 'OUTPUT'ports , recommended STP cable a) A:DATA + b) B:DATA - c) GND:better connect up the GND when used in long communication distance. 5,Make sure the module is fixed and working in air drying place after all connection has be done. Data protocol1,Serial parameters Baud rate:9600 Number of data bits:8 bits Verify digit:NONE Stop bits:1 Flow control:NONE 2,Descriptions of data The module send 2 frames each time, each frame bears 9 hexadecimal bytes, included 2 head public bytes(0XDD 0XDD), 2 module ID bytes, 2 effective bytes, 1 verify byte, 2 tail public bytes(0XAA 0X55). 3,Typical example DD DD 27 10 02 20 15 AA 55 DD DD:Head public bytes. 27 10:Module ID bytes, used for identification. 02:High significant byte for number 12/11/10/9 ports Example: 0000 0010 means number 10 port is closed, others are open. 20:Low significant byte for number 8/7/6/5/4/3/2/1 ports Example: 0010 0000, means number 6 port is closed, others are open. 15:Verify byte: ID high significant bytes^ID low significant bytes^effective high significant bytes^effective low significant bytes, here is 27^10^02^20 in this case. AA 55:Tail public bytes. |
