VDIS-2 VME Display and Diagnostic Module
VDIS-2 is the new, improved test and diagnostic module for VME-bus systems. It is equipped with LED's for all VME bus lines but also allows to trigger on error conditions, generate DTACK's and be adressed for read and wite VME calls.Different triggers in the VDIS-2 as for example hold the display on bus error or generate of DTACK after a time-out period allow to analyze the VME bus activities in detail. VDIS-2 is equipped with two different 32-bit registers liable to be read or written in different manners.
- Format: 6U, Size B, 1 Slots
- confirm to VME-bus ANSI/IEEE STD 1014, IEC821 and IEC297
- VDIS-2 visualizes the most important signals of the VME-bus by the help of large colored LED´s:
- 32 data and 32 address lines
- interrupt lines (IRQ1-7 , IACK, IACKIN)
- Bus Clear, Bus Busy, BG1 - BG3 and BR1 - BR3
- control signals (VD, CLK, RES, SYSF, ACF, AS, DS1, DS0, LWORD, DTACK, BERR)
- address modifier (AM0 - AM5)
- supply voltages (+5V, +/-12V)
- VME-bus-Slave D08(OE), D16, D32 and A16, A24, A32. Interrupt handler 1H(1-7)
- Low power CMOS-Technology: power consumption 1.4 A
- 32-bit read and write register, accessed if no board answers on the VME-bus after a suitable time-out and asserts DTACK
- 265 Byte VME-SHORT address area for extended test functions, fully programmable via VME
- Software control for all frontpanel switches
- Interrupt Logic for test purposes
- All addresses, data and VME-control lines are stored for each VME-cycle in a register for read-back
- 32-bit data register for read and write tests
- 32-bit test counter
