Table 118. CR800 Settings
Settings are accessed through the Campbell Scientific Device Configuration Utility (DevConfig) via direct-serial and IP connections, or through
PakBusGraph via most CR800 supported telecommunications options.
Setting Description Default Entry
Route Filters
This setting configures the CR800 to restrict routing or processing of some PakBus
®
message types so that a "state changing" message can only be processed or forwarded
by this CR800 if the source address of that message is in one of the source ranges and
the destination address of that message is in the corresponding destination range. If no
ranges are specified (the default), the CR800 will not apply any routing restrictions.
"State changing" message types include set variable, table reset, file control send file,
set settings, and revert settings.
For example, if this setting was set to a value of (4094, 4094, 1, 10), the CR800 would
only process or forward "state changing" messages that originated from address 4094
and were destined to an address in the range between one and ten.
This is displayed and parsed using the following formal syntax:
route-filters := { "(" source-begin "," source-end ","
dest-begin "," dest-end ")" }.
source-begin := uint2. ; 1 < source-begin <= 4094
source-end := uint2. ; source-begin <= source-end <= 4094
dest-begin := uint2. ; 1 < dest-begin <= 4094
dest-end := uint2. ; dest-begin <= dest-end <= 4094
Baud Rate
Applies to the following
communication ports:
RS232
ME
SDC7
SDC8
SDC10
SDC11
COM1
COM2
This setting governs the baud rate that the CR800 will use for a given port to support
PakBus
®
or PPP communications. For some ports (COM1 or COM2), this setting also
controls whether the port is enabled for PakBus or PPP communications.
Some ports (RS-232 and CS I/O ME) support autobaud synchronization (0 or -nnnn)
while, other ports support only fixed baud. With autobaud, the CR800 will attempt to
match the baud rate to the rate used by another device based upon the receipt of serial
framing errors and invalid packets.

This setting, in units of seconds, governs the rate at which the CR800 will broadcast
PakBus
® messages on the associated port in order to discover any new PakBus ®
neighboring nodes. It will also govern the default verification interval if the value of the
Verify Interval XXX setting for the associated port is zero.

This setting specifies the interval, in units of seconds, that is reported as the link
verification interval in the PakBus
® hello transaction messages. It will indirectly govern
the rate at which the CR800 will attempt to start a hello transaction with a neighbor if no
other communication has taken place within the interval.
