Ocal-S-1 parallel output display board adopts CAN bus interface to fulfill the function of lift hall call, which makes the input and output interface easier.
Parameter:
Working voltage: DC12V~DC24V
Working current: <250mA（DC24V）
Communication connection port: All the information shown on display use serial to input. Communication input port uses four core socket (of which two are power wire, two are signal wire). Only one piece of four core shied wire connects with CAN bus interface of lift micro controller, it can work.
