The RTU connectors
3 Performing Advanced
Functions
With the appropriate knowledge, you can configure the addNODE devices in the
field by using a HyperTerminal window. To configure the RTU, you will need a
special serial cable adapter (not supplied, available from Adcon).
Do not try to configure your addNODE devices if you are not sure what to do—the
unit may not communicate with the remote measuring station or function with the
addVANTAGE software.
Caution: When an A740 RTU was not used for at least a year, but the internal data memory
still holds some sensor data, the A740 must have its data memory initialized (see
the FDEV command in section 3.5.3).
Tampering with parameters of the addNODE devices may void your warranty or
damage the device. In general, the commands described in this chapter are
intended for technical support staff and skilled users with a great deal of highly
technical hardware and software experience.
In the system architecture, the base station and RTU are both considered to be
nodes. The base station is called the master node, or master, while the RTU is
called the slave node, or slave.
3.1 The RTU connectors
The addNODE devices have cable attachments called connectors. The connector
type determines how the device communicates with the sensors or the computer.
The addNODE RTU uses standard cage-clamps for all connections.
