Grating signal commonly used acquisition method:

1. Grating digital display table:Single axis   Two-axis / three-axis

2. Direct connection of PLC high-speed counting module (5V TTL or 5V differential signal input)

3. With four multiplier function of the computer counting board JJX-6000 (PCI interface, serial communication)
