VMIVME-5504L D32/A16 RS-485 VMEbus Repeater Link • Multidrop capability reduces cost • Differential line drivers and receivers provide ±7 V common-mode noise rejection • Software transparent link • Supports up to 1,000-ft cables • Supports the configuration of large I/O systems • Supports 8-, 16-, and 32-bit data transfers • Supports 16-bit addressing • Double Eurocard form factor • Link includes one master board, one slave board, and a wide variety of cable length options • DIN-type I/O connectors • Supports up to 16 slave-only chassis per master • Slave chassis is placed in reset if master chassis is powered down or cables are disconnected OVERVIEW — The VMIVME-5504L is designed to use a single master repeater board which may be connected to as many as 16 slave repeater boards using a single pair of cable assemblies with cable taps. This configuration allows SPECIFICATIONS VMEbus slave I/O boards residing in one VMEbus chassis to • 1,000-ft maximum cable length be controlled by a VMEbus master residing in another • Supports 8-, 16-, and 32-bit data transfers chassis. The VMEbus chassis in which VMEbus masters • Supports 16-bit addressing reside is referred to as a master chassis, while the VMEbus • Supports VMEbus slaves in slave chassis slave boards reside in a slave chassis. • Allows expansion to 19 x 19 x 16 slots using 20-slot backplanes. See Figure 1. A typical multidrop configuration is shown in Figure 1. • DIN format connectors This design concept allows the user to configure large I/O • Inexpensive ribbon cable interconnects subsystems using a minimum number of slots in the master • Double Eurocard form factor chassis. • The VMIVME-5504 slave board must be installed in slot 1 of the VMEbus slave chassis For users who require dedicated, high-performance, •A VMIVME-5504 slave is the only VMEbus master long-line links, a single master VMIVME-5504 Master may allowed in the slave chassis be connected to a single VMIVME-5504 Slave as shown in •Interrupts not supported Figures 2 and 3.
