CAMAC IBM Personal Computer Interface Type 1330 Product Description This dual–width CAMAC Crate Controller and Microcomputer Interface provides a fast efficient CAMAC port for machines like IBM PC, AT or compatibles. It is an ACB Master/Auxiliary controller in accordance with IEEE 675 (EUR 6500) simply by inserting or removing resistor packs. The front–panel bus connector carries 8 bi–directional data lines, 8 address lines and several control lines including interrupt–request. The controller is connected to the Microcomputer by a 34–way ribbon cable up to 20 feet long, with a capacity of 8 controllers. The cable is connected in most cases to a Personality Card in the Microcomputer, which positions the CAMAC in a suitable space in the address map. The controller is now offered with our new PCI Personality Card, the 5331. Turbo Version Type 1331 Hytec now manufacture an enhanced Turbo version of the highly successful 1330. This is the Turbo 1331, please see the data sheet for this additional product as it may further suit your requirements. Software Hytec provide a wide range of drivers and routines for both 1330 and 1331 Controllers. In addition to using Basic to drive the Controller through INP and OUT, there are ESONE Standard routines available for Windows 95, NT, 2000, XP and compatible with Visual C, Visual BASIC and Visual Fortran.
Encoded L Register When a LAM whose Mask bit is set to ’1’ is detected, the interrupt flag will be set in the Status Register, and the Encoded L Register will show the 5–bit station number of that module, along with three bits of data (most significant) controlled by internal switches. When no selected LAM is present, the Encoded L Register will show a random number. In the presence of a function code of 64 or more (Mask access) the Encoded L Register shows 5–bit ’L Selected’ (Lower 5–bits of F code) together with L Line State (bit 6) and Mask bit state (bit 7). 5331 PCI Personality Card The PCI Personality cad automatically requests areas of I/O space into which the 1330's register space is decoded. The registers form the lower 8 bits of consecutive 16 bit word addresses. |
