NetMax N8000 System Controller
Owner’s manual
The pins of the RS-232 interface used in the N8000 are indicated in the following illustration and
table. Connections which are not given are internally connected in the N8000 so that the
communication between the N8000 and the connected device is possible via a software
handshake system. The cable which is used for the connection should not be longer than
15 meters.
CONTROL PORT
The control port on the rear of N8000 is divided into two parts.
Two Phoenix connectors (6-pin) are included in delivery in
order to be able to connect external components.
Control Inputs
The upper part, which is marked as INPUTS 0-10V on the device, provides four freely
programmable control inputs for voltages between 0 volt and 10 volts. The inputs are numbered
in order from 1 to 4. The N8000 provides its own voltage supply for externaly connected
monitoring elements, e.g. potentiometers or switches. The voltage supply is available at the
10V REF and GND connectors of the control port.
