Parameter Description
RS 232C Baud Rate Baud rate of the RS 232C link between the host computer and the KF3.
The host computer and KF3 must be set to the same baud rate.
Possible rates are 300 (03), 600 (06), 1200 (12), 2400 (24), 4800 (48),
9600 (96), 19200 (19).
RS 232C Parity Parity of the characters on the RS 232C link. Parity can be None (00) or
Even (01). The host computer and KF3 must have the parity set to the
same value.
DF1 Device Category Sets the communication protocol to be used on the RS 232C link.
Choices are DF1 full duplex (00), DF1 half duplex slave, local mode (01),
or DF1 half duplex slave, remote mode (02). See Chapter 4,
Communicating with the KF3, for details.
Error Detection Two forms of error detection are available on the DF1 link: BCC Block
Check Code (00) or CRC16 Cyclic Redundancy Check (01).
The application program running on the host computer must use the same
error detection as the KF3. Refer to your application user's manual for
information on the type of error detection it is using, and set the KF3 to the
same value.
Flow Control Determines whether modem handshake lines are used for flow control:
disabled (00) or enabled (01).
Flow control is normally enabled when communicating with a modem.
Duplicate Message Determines whether duplicate message detection is disabled (00) or
Detection enabled (01).
When duplicate message detection is enabled, the KF3 will acknowledge
(and discard) duplicate messages.
Submenu Parameters Lets you into the submenu to set the advanced communication
parameters; the data display will show two dashes.
See the section on Advanced Communication Parameters for more
information.
Series and Revision Displays the series and revision level of the module. The first digit shows
the series (A J), the second the revision (A J). For example, Series A,
Revision B is displayed as AB." You cannot set this value.
