3594-4C SNet-PCI Interface What is the 3594-4C Snet-PCI Interface? The 3595 4C Interface card enables a PC, with PCI expansion slots, to communicate with the Solartron-Mobrey S-Net system. The card provides full timing control and error checking, in accordance with the S-Net communication protocol. 1.1.1 PC System Requirements The 3595 4C Interface card is fully compatible with a PC that has: • A free PCI expansion slot • A minimum of 128K user memory • Microsoft Windows Features Control commands for measurement set-up Measurement initiation Measured data retrieval Synchronised time stamping across the network DC Power to all connected IMPs Full timing control and error checking are performed on the data. The card occupies one slot in the PC, and contains its own data buffering. Data is exchanged with the PC via the 64K dual-port RAM which is divided into 512byte pages, each page dealing with a particular aspect of IMP operation. Several cards, each driving a separate S-Net, may be present in one PC if required. Each S-net supports up to 50 IMPs.

This power supply can be situated by the PC, using the S-net to supply each IMP, or may be local to the IMPs, supplying power directly to each IMP. Technical Specifications Connections Power Drain (on PC) 124-way edge connector for PCI expansion slot bus. 5V, 2.5W maximum 9-way D-type female connector for S-Net. 12V, 50mW maximum plus 1.2W for each 3595 Series IMP, and 1.8W for each Universal Series IMP, when powered from the internal power supply (Up to a maximum of 5 IMP devices). 9-way D-type male connector for external power. Environment Temperature Operating 0°C to 55°C (50% Relative Humidity) Power Drain (from external power supply, if used) 1.2W maximum per IMP. 0°C to 45°C (95% Relative Humidity) Storage -40°C to 70°C Requirements for external power supply, if used Communications (S-Net) capability 12 to 50V DC, dependent on system size and S-Net wire gauge. Maximum of 50 IMP devices Supply ripple less than 100mV rms. Maximum S-Net cable length of 1500m. Physical Dimensions S-Net Power Supply capability Overall length 6.8in. Up to 5 IMP devices (3595 Series) can be supplied, at limited distances, from the PC internal power supply. Overall height 4.2in. Overall width 0.8in. Up to 50 IMP devices (3595 Series) can be supplied from an external power supply. The actual number depends on the voltage of the external supply and on the length and gauge of the S-Net cable.
