9. Interface
9.1. Standard Serial Output
The standard serial output with 0 to 20 mA can be connected to a device such as an
A&D printer or remote display. The interface has no power source. Therefore, the
external devices to be connected must have a power source. The setting values of the
standard serial output are changed in the general functions
