CC16 W-IE-NE-R CAMAC Crate Controller Card

The W-IE-NE-R PC16 Interface Card connects the CC16 CAMAC crate controller with a standard personal computer AT or XT with 80X86 CPU. It is a 16-bit ISA-bus card of full length (AT-board). The PC16 can be used both in byte or word access mode to support XT or AT computers. The required mode is defined by jumper setting (jumpers 1-16). In case of XT - byte access mode two cycles for in- and for output are necessary. The CC16 allows an interrupt based LAM servicing. Both IRQ-number as well as I/O address for data transfer can be chosen by DIP-switches or jumper settings. The enabling / disabling of interrupt based LAM servicing is done on the CC16 and has to be performed by software. Further the ALE switch has to be in ON position. Up to 15 CC16 can be linked in parallel to one CC16 interface card. For control 15 geographical addresses (0-14) and one broadcast address (15) for parallel access is used.

The Wiener Plein and Baus GmbH PC16 - TURBO Interface Card was designed to accelerate the CAMAC control via IBM-PC. This interface card for the CC16 fits into a standard AT-long slot (word access only). The PC16 Turbo card contains a high integrated PLD circuit which allows to reduce the CAMAC controller access time by using a wider I/O port range. Thus this interface has a read / write rate between computer and CAMAC controller of up to 6µs/CNAF or up to nearly 1.5µs in block mode (measured with 486DX2-66). In case of cable length up to 15 metres one may use the internal 24MHz oscillator, in case of longer distances and / or a noisy environment it may be necessary to run the interface card with the standard 8MHz AT ISA bus clock.
