Received The total number of properly formed messages received by this Bay Cat X, whether they were
addressed to it or not
Replies Sent Counts the number of replies sent by this unit. It counts up to 32767 and then resets to 0
Last Packet Type The kind of packet that was last received. When using the ASCII RS-232 protocol, the possible
types are operation, event (for KY packets) and OEM (for ST packets) but other types are possible
when using the binary protocol (for internal and diagnostic use only). Most commonly, Last Packet
Type is an Event or an Operation. You might also see Bad CRC or Bad Header if the packet were
sent incorrectly
Last Packet Address This Unit Alone – The last packet was addressed to this unit and no others. It will be acted on and
answered
Global -- The last packet was addressed to this unit and also to others. It will be acted on but not
answered.
Not This Unit – The last packet was addressed to a unit or units other than this one. It will not be
acted on or answered
Not Addressed – The last packet was received with address -- or via the binary non addressed pro-
tocol. It will be acted on and answered. If multiple units are connected on the RS-232 chain, the
answer may not be properly received, since all units on the line will be “talking” at once
