Connection to the RS-232C port of the host computer (master)
A RS-232C/RS-485 converter is required.
The cable and termination resistor (s) must be provided by the customer.
W-BF-01 or W-BF-28 communication cable (RKC product) can be used as communication cable
(sold separately). If noise is a factor, customer should use a twisted pair cable (not included) or
something to that effect.
Recommended RS-232C/RS-422A converter:
COM-A
(RKC product)
For the COM-A, refer to the
COM-A/COM-B Instruction Manual (IMSRM33-E
)
