4. Configuration
The following chapters provide information for configuring the CP372 board for operation.
4.1 Jumper Settings
The CP372 does not have any jumpers which require configuring.
4.2 Analog Output Signal Requirements
In addition to the output signal types and their ranges which have been specified in chapter 1,
system integrators must be aware of the need for certain types of output and input configuration
requirements for the CP372. The following chapters describe each of the signal types with re-
gards to their individual connection configuration requirements.
4.2.1 Channels
The pinout of the CON2 connector of the CP372 is designed so that for each output channel
there are three output pins per channel available. This allows for each channel to be configured
separately as required. As can be seen from Figure 2-2, each channel’s respective pins are
grouped together starting at the top of the connector with channel 0 (cluster A). The configura-
tion of each channel is dependent on the type of analog output signal generated by the CP372.
The following chapters address the basic requirements for each type of possible signal.
4.2.2 Analog Voltage Output Signals
The analog voltage output signals are single-ended with a variety of ranges: uni-polar: 0V to
5V and 0V to 10V; and bipolar: -5V to +5V and -10V to +10V. The current of each output is
limited to 5 mA. For the ranges 0 to 5 volts and - 5 to + 5 volts, a load of at least 1 k ohm is
required. For the ranges 0 to 10 volts and - 10 to + 10 volts, a load of at least 2 k ohm is re-
quired.
Signals of this type are required to be connected: plus to plus, and ground to ground. Refer to
Figure 4-1 for this type of connection.
