VMIVME-REPEAT L VMEbus Repeater Link • Supports 8-, 16-, 32-bit transfers • Supports 16-, 24-, and 32-bit addressing • Repeats VMEbus P1 and P2 • Propagation delay is approximately 150 ns • Supports all seven interrupt levels • Supports VMEbus slaves on a slave-only VMEbus • Supports up to 50-foot cables • Allows expansion to 19 x 19 slots using 20-slot backplanes in a star conŢguration • Double Eurocard form factor • DIN-type I/O connectors • Links include one model REPEAT M, one model REPEAT S, and a variety of cable lengths REPEATER LINK OVERVIEW — The VMIVME-REPEAT L is a two-board set which allows VMEbus slave I/O boards residing in one VMEbus chassis to be controlled by a VMEbus master residing in another chassis. The VMEbus chassis in which VMEbus masters reside is referred to as a master chassis, while the VMEbus slave PHYSICAL/ENVIRONMENTAL boards reside in a slave chassis. The two-board set is Temperature Range: 0 to 55 °C, operating configured as shown in Figure 1 with one board designated for -20 to 85 °C, storage the master chassis while the other board is designated for the slave chassis. A master VMEbus chassis can communicate Relative Humidity Range: 20 to 80 percent, with several slave chassis by using multiple noncondensing VMIVME-REPEAT Links, as shown in Figure 2. Cooling: Convection The VMIVME-REPEAT Link supports all seven interrupt levels. Interrupts are acknowledged by the IACKIN*/IACKOUT* daisy chain which is routed through all of the slave chassis slots before going on to the next VMEbus master chassis slot. Thus, any slot in the slave Ordering Options chassis can generate an interrupt.
