CHAPTER 5. Cautions
•
Options should be installed with the power supply turned off.
•
When setting the RS232C channels, avoid setting two or more
ports to the same channel. The ER-A570 allows installation of
max. two units of the ER-A5RS. In this case also, avoid setting two
ports of the ER-A5RS to the same channel. If not, the hardware
may be damaged.
•
Concerning the inspection items whose display formats are not
presented in this test function, nothing appears on the display
