connector, and four 8-pin RJ-45 serial connectors on the front panel.
In addition, the panel has cutouts for routing of flat cables to the
optional IndustryPack modules.
The following ASICs are used on the MVME162LX:
❏
VMEchip2. (VMEbus interface). Provides two tick timers, a
watchdog timer, programmable map decoders for the master
and slave interfaces, and a VMEbus to/from local bus DMA
controller, a VMEbus to/from local bus non-DMA
programmed access interface, a VMEbus interrupter, a
VMEbus system controller, a VMEbus interrupt handler, and
a VMEbus requester.
Processor-to-VMEbus transfers are D8, D16, or D32.
VMEchip2 DMA transfers to the VMEbus, however, are D16,
D32, D16/BLT, D32/BLT, or D64/MBLT.
❏
MC2chip. Provides four tick timers, the interface to the LAN
chip, SCSI chip, serial port chip, BBRAM, EPROM/Flash,
parity DRAM and SRAM.
❏
MCECC memory controller. Provides the programmable
interface for the ECC-protected DRAM mezzanine board.
❏
IndustryPack Interface Controller (IP2). The IP2 provides
control and status information for up to two single-wide
IndustryPacks (IPs) or one double-wide IP that can be
plugged into the MVME162LX main board.
