In order to connect JP2 with a PC’s RS232 port, an intermediate level shift buffer is necessary [buffer component:
ADM232]. The CA-MRS232-6 and CA-MTUSB-60 tuning cables has the level shift buffer built-in. RxD and TxD
RS232 signal from connector JP2 is TTL/CMOS level.
Do not connect servo drive directly to PC RS232 port without buffer component.
