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 powerup/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.

Operation
Reading or Writing to the Board Control of the PCIB40 is achieved by writing to a pointer register and then accessing a data register to read or write the required I/O register. The pointer register need only be written with a new value if a different register is to be accessed. The board occupies only two bytes of PCbus I/O space. Each time the board is accessed, the red LED will flash momentarily.
Digital I/O channels To use a digital channel (or bit) as an output simply write to that channel (or bit). To use a digital channel (or bit) as an input write a `1' to the channel to initialise . Thereafter a read can be used. You can configure each digital channel (or bit) as an input or an output but it is advisable to configure the board in groups. e.g. Group 1,2 & 3 output, Group 4 & 5 input. When an output is set to `0' (logic low) it is not advisable to attempt to drive the external connection to logic high. Reading a digital channel, when it is an output, will return the state of the output. This can be useful if you need to check the status of an output. Electrical configuration of each digital channel:

Read Status
Power-up or reset state of outputs When digital I/O boards are used to control large or crucial items of plant, it is often necessary to define how the output lines power-up. This is because it can take many seconds to boot an operating System and run an application program from reset and begin initialising the system. Each group of eight I/O signals can be selected to be a logical `0', a logical `1' or `don't care' at power-up or on reset. This is configured using jumpers (see links section). To use this feature set the links for the power-up or reset condition required. Then in your code write to the group registers the output levels required, and finally enable the outputs by writing a `1' to bit 0 of register 90 (hex). Note: This feature is suited to outputs not inputs. Setting an input to a power-up state of `0' will require the group register being written with all `1's' to enable the use of the channels as inputs.

Counter Timers
2192-09066-000-000
The PCIB40 includes three programmable 16-bit counter/timers. Counter 0 may be driven by either a 10KHz, 100KHz or 1MHz clock and can be used to generate regular interrupts. An interrupt is generated only when the counter 0 output goes to a `1'. The input and gate control signals of counters 1 and 2 are connected as inputs from the D-50 while the counter outputs are linkable to the D-50 connector. Counter inputs 1 and 2 may be used for frequency or pulse measurement and the outputs used for pulse generation. Refer to the link section and pin assignments table for connection details.
I/O map
The value written to the pointer register is used to select the on-board I/O location to be accessed. This board occupies two consecutive addresses and has nine I/O function registers and three special function registers. The board must be set on an even address boundary.

Links 3 & 4 Counter 1 and 2 Output Select
The outputs from counter 1 and 2 can be connected to the D-50 connector using LK4 and 3 respectively. NOTE: The counter outputs are interfaced to the I/O connector using an inverting open-collector driver. The output state is therefore the inverse of the counter output state defined in the data sheet. When using the counter outputs, it is necessary to ensure that the I/O signals for group 2, bits 0 and 1, are set for input mode by writing `1's to both bits. This avoids the counter output conflicting with the I/O port output. LK3 LK4 Connects T2 output via inverter buffer, to RC24 (Digital group 2, bit 1) Connects T1 output via inverter buffer, to RC23 (Digital group 2, bit 0)
