J206 PCIB40 Technical Manual
Introduction
The PCIB40 is an 8-bit ISA bus add-on board providing 40 channels of digital I/O and three 16-bit
counter/timers. The digital I/O is organised into 5 groups of 8 bits. Each I/O channel may be
configured as an input or an output. The board also includes the facility to define the power-
up/reset state of a group of output bits. This is extremely useful in ensuring the safe start-up of a
PC-controlled system. The 3 counter/timers are implemented using the industry-standard 8254
device. One timer can be used as a periodic interrupt generator while the other two timers can be
connected to external signals for frequency measurement and pulse generation.
The D-50 I/O connector conforms to Arcom’s standard Signal Conditioning System (SCS) and may
be used to drive a range of Signal Conditioning Boards (SCB); see Arcom’s PCbus catalogue for
more details.
