7.1
Communications Specifications
This section describes the specifications for the RS-232C interface and the connec-
tion between the KV and external devices.
7.1.1
Communications Specification
The communications specification of the KV is summarized in the table. Set the
communications parameters of the personal computer by referring to the table.
Communications parameters
Note 1: Be sure to specify the same communication parameters for the KV and any
external devices to be connected. Communication will fail if different parameters are
used.
Note 2: Refer to the instruction manual supplied with each device when setting
communications parameters on the device.
7.1.2
Connection with the KV Unit
Use the special connection cable (Straight cable: OP-26487, Reverse cable: OP-
96607) and a 25-pin D-sub connector (OP-26485) to connect the KV to the RS-232C
connector of the external device.
Note: The KV-10xx and KV-10/80 Series include only communication port A.
