Transmission rate and maximum distance: Different rates correspond to the maximum length of different bus segments (based on cables with impedance of 135-165 Ω and capacitance per unit length ≤ 30pF/m), as follows:
Rate (kbaud) 9.6 19.2 93.75 187.5 500 1500 6000
Maximum length (meters) 1200 1200 1200 1000 400 200 100
Software troubleshooting: When software malfunctions, the module will enter a fail safe mode to ensure system safety.
2. Power supply and mechanical specifications
Power supply: Railbus (12V) with a typical current of 420mA and a maximum current of 520mA at -40 ° C.
Mechanical dimensions: The module width is 63mm and the weight is approximately 350g.
3. Meaning of LED indicator lights
Feedback various operational information of the module through the on/off and flashing status of different colored LEDs, as follows:
Meaning of indicator light status
Power (green) OFF power failure
ON power supply is normal
Blinking/
Fault (red) OFF Normal
ON fault safety mode or malfunction
Blinking/
Communication (yellow) OFF internal status (when powered on)
ON Internal Status
Flashing communication fault (flashing)/Communication is normal (flashing, context needs to be considered)
LAN A (yellow) OFF power off
ON LAN has activities
Blinking without LAN activity (slow flashing)
Configuration (yellow) OFF undefined (error exists)
ON configurator connected
Flashing configurator not connected
Railbus (yellow) OFF Railbus fault
ON Railbus is normal
Flashing without corresponding status
