With the appropriate knowledge, you can configure the A73x devices in the field by
using a HyperTerminal window. To configure the RTU, you need a special serial
cable adapter (not supplied, but available from Adcon).
Do not try to configure your A73x devices if you are not sure what to do—the unit
might not communicate with the remote measuring station or function with the
addVANTAGE software.
Tampering with parameters for the A73x devices may void your warranty or
damage the device. In general, the commands described in this chapter are
intended for technical support staff and 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 Understanding connectors
The A73x devices have cable attachments called connectors. The connector type
determines how the device communicates with the sensors or the computer.
3.1.1 The RTU connectors
The A73x RTU uses standard 7-pin sensors for all available I/O ports (A731
addRELAY excluded), model Binder 702 and 712 series or equivalent, that are
identical. Each connector has three analog inputs (0 to 2.5 volt) and two digital
input/outputs, one of which you can use as a pulse counter (for example, a rain
gauge). Fig. 9 illustrates the individual pins of an I/O connector.
