The Serial Encoder Board CH032 is designed to be used in conjunction with serial controlled display units. The protocol used in the communication link between the display card and the encoder units are proprietary and subject to change without prior warning or notice. The encoder has two serial output communication ports SER1 and SER2 and is installed in the lift machine room, next to the lift controller. It accepts signals like floor position code, directional arrows, gongs, as well as lift status signals like MAINTENANCE, OVERLOAD OUT OF ORDER etc. through 32 opto-isolated inputs.
