The IS420UCSBH1A is a processor-based computer with a fully compatible IBM PC/AT Celeron processor. It has the added advantage of a single European card structure and full compatibility with version C.1 of the VMEbus specification. In addition, it has an advanced VMEbus interface and RAM, and dual ports to VMEbus are ideal for multi-processor applications.
The IS420UCSBH1A can be accessed as a VMEbus slave board, and the functionality can be implemented by programming the PCI to VMEbus bridge of the VMIVME-7698. In addition, it is possible to select optional PCI to VMEbus interface boards based on the references defined in this volume and/or Volume II.
In terms of data recording and storage, IS420UCSBH1A usually supports data recording and storage functions, which can store the collected data in internal memory or external storage devices.
It should be noted that the functions and application fields of different products may be different due to specific application scenarios and needs, so it is necessary to evaluate and select according to the actual situation in the use process. At the same time, in order to ensure the safe and stable operation of the system, it is also necessary to carry out regular maintenance and inspection.
