The CRD5100 Series Data Stream Digital Transducers are designed for
complete monitoring of electrical power systems. The digital technolo-
gy is used to measure voltage, current, power frequency and energy in
single and three phase designs. The data is streamed over an RS485
IEEE bus which enables multiple transducers to communicate thru a sin-
gle master connection. These advanced sensors are ideal for entire
plant or zone monitoring. Also, the communication alagorithm can be
pre-ordered with ASCII based control or modified MODBUS based
control.
Note: Add an M at
the end for MODBUS

ASCII Simplified Programming Commands
A simplified data structure is used with only 6 commands required for full control of
the transducer. Commands are : Read Transducer Name, Read Configuration, Set
Configuration, Read Measurements, Read Energy Totalizer and Clear Energy
Totalizer. For illustration, the following commands are used to read data from a
CRD5170 3 Phase, 4 Wire Transducer with a device address of 00.
Command Transducer to Read Data: #00A<cr>
