Chapter 1

Introducing the PCI-QUAD-AC5

Overview: PCI-QUAD-AC5 features

The PCI-QUAD-AC5 is a 96-bit, high output, digital I/O board for PCI-compatible computers. Primarily designed as a direct interface to the industry-standard SSR-PB24 rack, the board is also highly useful as a general purpose digital I/O board.

The 96-bits of digital I/O are organized into four 24-bit groups based on an 82C55 mode 0 emulation (no strobed I/O or bi-directional I/O bits). Each 24-bit group is divided into three eight-bit ports labeled

PORTA, PORTB and PORTC. PORTC can be split into two four-bit nibbles — Port C-HI and Port C-

LO. Each of these ports may be individually programmed as input or output.

All inputs and outputs are TTL compatible. The digital output drivers are 74S244 chips that can sink

64 mA and source 15 mA. The input buffers are 74LS373 chips and have standard high input impedance of the 74LS series devices. All I/O is brought out to a 50-pin connectors, which also allows connection to the PC’s +5 Volt and Ground.

On power up and reset, all I/O bits are set to input mode. If you are using the board to control items that must be OFF on reset, install pull-down resistors. Each board is equipped with open locations where you can install SIP resistor networks for either pull-up or pull-down.

The PCI-QUAD-AC5 board is completely plug-and-play, with no jumpers or switches to set. All board addresses and interrupt sources are set by the board's plug-and-play software. Board configuration is controlled by your system's BIOS.

Software features

The following software ships with the PCI-QUAD-AC5 free of charge.

ƒ InstaCal installation, calibration, and test utility

ƒ TracerDAQ™ suite of virtual instruments

ƒ SoftWIRE® for Visual Studio® .NET graphical programming

ƒ MCC DAQ Components for VS .NET (installed with SoftWIRE® for VS .NET)

Functional Details

Signal connections

All digital inputs and outputs on the PCI-QUAD-AC5 connector are TTL and are fully compatible with the inputs and outputs on the industry-standard PB-24 rack (Measurement Computing Corporation's model SSR-PB24).

82C55 emulation

The PCI-QUAD-AC5 board emulates the 82C55 chip. The 82C55 emulation initializes all ports as inputs on power-up and reset. A TTL input is a high impedance input. If you connect another TTL input device to the output, it could be turned on or off every time the board is reset.

To establish a consistent TTL level at power-up, use resistors tied to either +5V (pull-up) or ground

(pull-down). There are open locations for pull-up and pull-down resistor SIPs on the board.

When an 82C55 emulation is powered on or reset, all pins are set to high-impedance input. Based on standard TTL functionality, these inputs will typically float high, and may have enough drive current to turn on external devices.

Consequently, if you have output devices such as solid state relays, they may be switched on whenever the computer is powered on or reset. To prevent unwanted switching, and to drive all outputs to a known state after power on or reset, pull all pins either high or low through a 2.2 K ohm resistor.

Pull-up and pull-down resistors

TTL inputs typically float high, but not reliably. The direction they float is dependent on the characteristics of the circuit and is unpredictable. If devices such as solid state relays are driven by digital

I/O pins, they can be switched on whenever the computer is powered on or is reset. To prevent unwanted switching at power-on or reset, force all digital I/O pins to a known state by pulling all pins either high or low through a 2.2 K ohm resistor tied to either 5V or GND.

The pull-up resistor pulls the input to a high state (+5V) when the board is in input mode, as it would be on power-up or reset. A 2.2 K ohm resistor draws only 2 mA. A grounded 2.2 K ohm pull-down resistor pulls the I/O line low when the board is in input mode.

The SIP is made up of eight 2.2 K ohm resistors. One side of each resistor is connected to a single common point and brought out to a pin. The common line is marked with a dot or line at one end of the

SIP. The remaining resistor ends are brought out to the other eight pins (refer to Figure 4-3 ).

PCI-QUAD-AC5 User's Guide Functional Details

The PCI-QUAD-AC5 board has open locations where you can install a 2.2 K ohm, eight-resistor single inline package (SIP) resistor network for each port. Each of the four port locations is identified by the bit range — the First Port connector (P1) is labeled Bits 1 to 24 , the Second Port connector (P2) is labeled

Bits 25 to 48, the Third Port connector (P3) is labeled Bits 49 to 72 , and the Fourth Port connector (P4) is labeled Bits 73 to 96 . Pull-up/pull-down SIP locations (3 per port) are labeled A , B and C , and are

adjacent to each port. Refer to Figure 4-4.

Second Port First Port Fourth Port Third Port

SIP locations

A, B, C (3 per port)

Figure 4-4. PCI-QUAD-AC5 layout and SIP locations

When installed, the SIP establishes either a high or low logic level at each of the eight

I/O lines on the port. At each board location, A, B, and C, there are 10 holes in a line. The hole on one end is marked "HI" and is connected to +5V. The other end is marked "LO" and is connected to GND.

The eight holes in the middle connect to the eight lines of the port, A, B or C.

To pull-up lines, orient the SIP with the common pin (dot) toward the HI end; to pull-down, install the resistor with the common pin in the LO end.

Figure 4-5 shows a schematic of an SIP installed in both the pull-up and pull-down positions.

PCI-QUAD-AC5 User's Guide Functional Details

Unconnected inputs float

Unconnected inputs typically float high, but not reliably. If you are using a PCI-QUAD-AC5 board for input and have unconnected inputs, ignore the data from those lines. You do not have to terminate input lines, and unconnected lines will not affect the performance of connected lines. Ensure that you mask out any unconnected bits in software.

TTL to solid state relays

Many applications require digital outputs to switch AC and DC voltage motors on and off or to monitor

AC and high DC voltages. These AC and high DC voltages cannot be controlled or read directly by the

TTL digital lines of a PCI-QUAD-AC5.

Solid State Relays (SSRs) allow control and monitoring of AC and high DC voltages and provide 750 V isolation. SSRs are the recommended method of interfacing to AC and high DC signals.

The most convenient way to use solid state relays and a PCI-QUAD-AC5 board is to purchase a Solid

State Relay Rack. The rack recommended for use with the PCI-QUAD-AC5 board is the SSR-PB24 from

Measurement Computing Corporation.
