Restrictions in the use of the FX3G-422-BD
When connecting a device (such as GOT) which consumes an internal 5 V DC to each of the RS-422 port
built in the main unit and the FX
3G-422-BD at the same time, avoid continuous use of either device.
If both devices are used continuously, their life may be shortened due to heat generation.
