TYPICAL DATA ACQUISITION SYSTEM
Figure 8. Typical Data Acquisition System
Because of the flexibility of both the CR1000 and the radio, several parameters must be setup to
define the operation of the data acquisition process used to get data from the CR1000 to the radio
RAM data transmit queues. The following sections show the configuration and control command
structure as it relates to the CR1000 driver, and then discusses each command in detail.
The MRC-565 interface to the CR1000 using Campbell Scientific PAKBUS protocol. A
PAKBUS ID must be assigned to the MRC-565 before communications can occur. You can
assign the ID with the following command:
PAKBUS,ID,nnn
Where nnn is the ID. You can use any ID from 1-4095, but it must be different than the ID used
for the CR1000. The CR1000 is typically programmed with ID = 1. To verify the MRC-565 ID
enter the following command:
PAKBUS
The following data is returned:
PAKBUS 05/07/14 14:46:28
ID :nnn
Interval : 60
INF : 15
