1: The AJ61QBT11 of hardware version F or later and the A1SJ61QBT11 of hardware version G or later are compatible with this setting.
For other than the above, the setting is 1 or 4 stations only.
2: Each of Ver.1.10 compatible CC-Link cables, CC-Link dedicated cables (Ver.1.00), and CC-Link dedicated high performance cables
must not be used together with other cable types.
If different cable types are used together, normal data transmission is not guaranteed.
Also attach the terminating resistor which matches the kind of the cable. (Refer to section 7.5)
