CP372 4. Configuration 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 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.
Configuration CP372 Figure 4-1: Analog Voltage Signal Output Configuration Example for Cluster A + + + Rload + Rload pin 19 (VOUT1) pin 18 (VOUT2) pin 17 (VOUT3) Rload pins 38 to 41 (AGND) CON 2 analog ground 4.2.3 CP372 Analog Current Output Signals The analog current output signals are single-ended with a range of 0 to 20 mA. Signals of this type are required to be connected: Rs to I and analog ground to . Refer to Figure 4-2 for this type of connection.
CP372 Configuration The following two figures, Figures 4- 2 and 4-3, provide examples of the configuration of analog current signal outputs. Figure 4-2 indicates a configuration where the external source voltage (Vext) is the same for all four channels of cluster A. This example demonstrates the use of the common tie point pins for Vext.
Configuration CP372 Figure 4-3 demonstrates a configuration for cluster A where each output channel’s external source voltage is different due to different source resistances (Rs).
CP372 4.2.4 Configuration External Cluster Enable/Disable The CP372 provides two possibilities to enable or disable all the outputs of an entire cluster at one time. Each individual cluster may be controlled either per software or hardware, whereby the hardware control has priority over the software control. Information regarding the software control is provided with the driver software. The hardware control capability is described as follows.
Configuration 4.2.5 CP372 Analog Ground Usage Analog ground usage must be carefully considered in order to avoid ground loops or floating signals which can ultimately lead to the degradation of the system performance. The figure below indicates the nominal analog grounding situation, but is, of course, very much subject to the requirements of the application as a whole.
CP372 Configuration 4.3 Programming Interface 4.3.1 Access Control Logic All the resources of the CP372 are mapped within the 64KB PCI memory address space which itself is set in the PCI configuration register BAR0. The port size of all local or backend registers is 32-bit by default. The address map of the registers is as follows.

CP372 System Considerations 5. System Considerations 5.1 Introduction 5.2 General Considerations: 1. For output channels, the I or V pins respectively are not to be connected except when required. 2. It is recommended to use twisted pair wiring for output signals. 3. Mixing of output signal types to be generated by the CP372 is permitted. 4. The type of signal expected to be generated for each output channel of the CP372 must correspond to the driver software configuration for that channel.
System Considerations 5.5 CP372 Cable Interfacing Considerations: 25780.01.VC.021121/111238 PRELIMINARY 1. No modification to the CP372 itself is permitted (i.e. connector pin shorting). 2. The resistance of cabling contacts should be kept to an absolute minimum. In any event the contact resistance must be taken into consideration when determining the signal conditioning requirements of the application.
