Name Type Description
HopMetric Byte A code used to indicate the worst case interval
for the speed of the link required to complete a
transaction (default value of 0x02):
0x00: 200 msec or less
0x01: 1 sec or less
0x02: 5 sec or less (default for RS232 or
TCP/IP)
0x03: 10 sec or less
0x04: 20 sec or less
0x05: 1 min or less
0x06: 5 min or less
0x07: 30 min or less
VerifyIntv Uint2 Link verification interval in seconds
Hello Response Message Format (MsgType 0x89):
Name Type Description
MsgType Byte Message type code (0x89)
TranNbr Byte Transaction number
IsRouter Byte Indicates whether the source node is a router.
The application should specify 0x00 (False)
indicating it is not a router in the response
message.
0x00: False
0x01: True
HopMetric Byte A code used to indicate the worst case interval
for the speed of the link required to complete a
transaction (default value of 0x02). The
application should copy the value from the
command message :
0x00: 200 msec or less
0x01: 1 sec or less
0x02: 5 sec or less (default for RS232 or
TCP/IP)
0x03: 10 sec or less
0x04: 20 sec or less
0x05: 1 min or less
0x06: 5 min or less
0x07: 30 min or less
VerifyIntv Uint2 This value is the link verification interval from
the Hello Command message divided by 2.5.
2.2.3 Hello Request Message (MsgType 0x0e)
A one-way message used to trigger a Hello transaction from the recipient. Use
this message to initiate communication with a node when the address of the
node is not known. If the application receives a Hello Request message from a
datalogger, the best course of action is to return a Hello Message to the
datalogger.
