Parameter Number Parameter Description Factory Default
RSĆ232C Parameters
RSĆ232C Baud Rate Baud rate of the RSĆ232C 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).
9600 baud (96).
RSĆ232C Parity Parity of the characters on the RSĆ232C link. Parity can be None (00) or
Even (01). The host computer and KF3 must have the parity set to the
same value.
None (00).
DF1 Device Category Sets the communication protocol to be used on the RSĆ232C link.
Choices are DF1 fullĆduplex (00), DF1 halfĆduplex slave, local mode (01),
or DF1 halfĆduplex slave, remote mode (02). See Chapter 4,
Communicating with the KF3, for details.
FullĆduplex (00).
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.
BCC (00).
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.
Disabled (00).
Duplicate Message
Detection
Determines whether duplicate message detection is disabled (00) or
enabled (01).
When duplicate message detection is enabled, the KF3 will acknowledge
(and discard) duplicate messages.
Enabled (01).
