AVW200-series 2-Channel Vibrating Wire Spectrum Analyzer Modules
the AVW200. If more than one AVW200 is used and the
instructions are ran in a sequential mode, a different result
variable should be specified for each AVW200 (see 6.1.2).
The result codes are as follows:
Code Description
0 Communication successful. Values have been
written to the destination array.
>1 Number of communication failures. NAN values
will be stored in the destination array. Resets to 0
upon successful communication.
-3 First communication. Values will be available on
the next scan.
ComPort The ComPort parameter is used to specify the
communications port that will be used to communicate with
the AVW200. Enter a numeric or alphanumeric code:
Alphanumeric Description
ComRS232 AVW200 connects to datalogger’s RS-232
port via 18663 cable
ComME RF401 connects to datalogger's CS I/O
port; RF401 configured as modem enabled
ComSDC7 RF401 connects to datalogger's CS I/O
port; RF401 configured as SDC7
ComSDC8 RF401 connects to datalogger's CS I/O
port; RF401 configured as SDC8
ComSDC10 RF401 connects to datalogger's CS I/O
port; RF401 configured as SDC10
ComSDC11 RF401 connects to datalogger's CS I/O
port; RF401 configured as SDC 11
Com1 AVW200 connects to datalogger's control
ports 1 & 2 via 17855 cable
Com2 AVW200 connects to datalogger's control
ports 3 & 4 via 17855 cable
Com3 AVW200 connects to datalogger's control
ports 5 & 6 via 17855 cable
Com4 AVW200 connects to datalogger's control
ports 7 & 8 via 17855 cable
NeighborAddr The NeighborAddr is used to specify a static route to the
AVW200 (e.g., the PakBus address of a "neighbor" device
that the host can go through to communicate with the
AVW200). If 0 is entered, the AVW200 is assumed to be a
neighbor (i.e., the host datalogger can communicate with the
AVW200 directly).
PakBusAddr The PakBusAddr parameter identifies the PakBus address of
the AVW200 with which the host datalogger is trying to
communicate. Valid entries are 1 through 4094. Each
PakBus device in the network must have a unique address.
Dest The Dest parameter is the variable array in which to store the
results of the instruction. Dest is a single-dimensioned array
of 5 or 6 (depending upon whether a thermistor is being
measured) if only one sensor is being measured. Dest is a
