ESD VME-PMC-CADDY-T I/O Controller - VMEbus base board for two single PMC modules, P2-pin assignment acc. to PMC-Update from 22.10.96 (no interconnection between PMC-modules) extended temperature range: -40...+75 Simple Type: I/O Controller The VMEbus unit PMC-CADDY is a VME64 base unit that can carry up to two PMC modules of normal size or one module of double size. For the VMEbus connection, the VME-PCI Bridge UNIVERSE CA91C142 by Tundra With an internal clock rate of 33 MHz is used. The CA91C142 interface can operate either as either slave or as Master on the VMEbus. If the board operates as master, it supports a 4-level arbiter. The PMC-CADDY operates with a data width of up to 32 bits and with 32 address signals on the VMEbus. You can apply the VMEbus interrupt to any of the seven interrupt-request lines. The board connects to the VMEbus by two 160-pin VG-connectors according to IEC603-xx on VME64 extensions. A red LED shows an active VMEbus-interrupt request in the front panel and a yellow LED shows a VMEbus access onto the board. Draft standard IEEE P1386/Draft 2.0 is the standard used for both PMC plug-in units' design except for the standard I/O pin routing. This design makes it possible to insert any PMC modules on the market. In addition to the connectors for the PMC address/ data and control signals, every plug-in unit of the PMC-CADDY has an I/O-connector that applies the I/O signals of the PMC modules to VMEbus connector P2. Two different P2 pin assignments are available: In the standard configuration, each P2-pin connects to one I/O-pin of the PMC modules (acc. to PMC-Update of FORCE ™, Table 1, Author: Wayne Fischer, Director of Strategic Programs CMC/PMC Working Groups Chair, 22.10.96). In the option -32P, the pin assignment is acc. to IEEE P1386/Draft 2.0, Table 6-3. This pin assignment offers to connect the two PMC-modules via P2, because several PMC-I/O-signals short at P2.
