• PCI-P8R8 / PCI-P16R16
The PCI-P16R16 and PCI-P8R8 are relay actuator output / isolation
input interface cards for PCs and compatible computers. The former provides
16 channels and the latter provides 8 channel input and output channels.
Both can be easily installed in a 5V PCI slot and can support truly “Plug and
Play＂. They can be used in many applications.
• PCI-P16C16
The PCI-P16C16 provides 16-channel transistor outputs and 16-channel
isolated digital input. The transistor can outputs up to 30Vdc / 600mA(open
collector). The isolated digital input, like the PCI-P16R16, provides AC/DC input
and R/C filter.
• PCI-P16POR16
The PCI-P16POR16 provides 16-channels PhotoMos Relay output and
16-channel isolated digital input. The PhotoMos relay output can switch up to
350Vac / 130mA (max.), with designed LED indicated for output status. The
isolated digital input, like the PCI-P16R16, provides AC/DC input and R/C filter.

1.4. Hardware Configuration
This chapter describes how to unpack this I/O card and how to
install it to your system. Both the unpacking information and the jumper
settings are described in the following text. This manual should be
carefully read before installation.
1.4.1. Unpacking
This I/O card was well-tested and inspected both mechanically and
electrically before shipping. It was free of marks and scratches our
quality delivery policy requires that all equipment be in perfect order
before delivery. However, some unconditional damages may occur while
unpacking!! Please read this section before unpacking the card. Feel free
to contact your carrier and retain your carton in case there is error.
CAUTION:
This card contains sensitive electronic components that can be easily damaged by
static electricity.
1. This card should be packed with an anti-static mat.
2. The user should wear an anti-static wristband, grounded at the same point
to the anti-static mat.
3. Inspect the carton for obvious damage. Either shipping or handing may
cause damages!! Be sure there are no shipping and handing damages on
the card before using.
4. After opening the carton, place the system board handle on a grounded
anti-static surface and let the component side up.
CAUTION: Do not apply power to the board if it has been damaged!
• You are now ready to install your card.

1.4.3. Jumper Setting
• For PCI-P8R8 / P16R16 / P16C16 / P16POR16
You can change the I/O card configuration simply by setting the
jumpers on this board. Each digital input channel can be jumper-
configured as a single-pole, RC filter with a time constant of 1.2 ms. The
table listed below shows each digital input channel and the
corresponding jumper.

the AC FILTER is optional. If the DC input signal response is less than
20 µs, set the filter to off. If you want a slow response (about 5 to 10 ms)
to reject either noise or contact bouncing, short AC FILTER Pin2-3.

2.1 Relay Output
• For PCI-P8R8 / PCI-P16R16 Only
Whenever data is written data to the output control register, the relays will
switch to NC or NO as specified by the control code. A｀1＇in the control
register will energize the corresponding relay. The relay will switch from COM to
NO (normally open ). A ｀0＇ in the control register will turn off the
corresponding relay and the relay will be switch from COM to NC (normally
closed). The control register powers-on in NC mode. A hardware reset signal or
programmable reset signal will also turn the relay to NC!!

Although the normal input voltage range is 5 to 24V AC or DC, the input
can still be changed to a larger range by choosing suitable external resistors.
The following figure shows how to connect to a larger input. Please note that
the input current should be limited between 2mA to 20mA; too large an input
current will burn down the internal resistor Ri, while too low of an input current
will not active the photo-coupler isolator. Calculate input voltage and current,
then replace resister Ri.

We’ll get:

If you replace 1.2KΩ as resistor Ri, we can calculate the power consumption of
Ri as follows:

P = I
Rex = (10mA) 2 * 1.2KΩ = 1.2W
The power consumption is 1.2 watts, but choosing 1.5 or 2 watts is better.
Thus, we can choose a 1.2K / 2W resistor to replace the resistor Ri.

The First 16 double words of a PCI device's configuration space is referred
to as the device's configuration region. Within these the 16 (0-15) double words,
the 04, 05, 06, 07, 08 and 09 double words are referred to as Base Address0,
Base Address1, Base Address2, Base Address3, Base Address4 and Base
Address5. For more detailed information for about these 16 double words,
please referring the book titled PLUG AND PLAY SYSTEM
ARCHITECTURE(written by Tom Shanley, Addison-Wesley Publish Company,
1995). These base addresses are utilized as control register and/or I/O register
for many data acquisition boards. On PCI-P16R16 and PCI-P8R8 boards, the
base address2 is utilized as the base address of digital in and digital out. So the
Digital I/O functions for PCI-P16R16 and PCI-P8R8 are coded as follows:
#define WORD unsigned int
#define UCHAR unsigned char
void P16R16_DO(WORD BaseAddr, WORD wOutData)
{
outport(BaseAddr,wOutData);
}
WORD P16R16_DI(WORD BaseAddr)
{
WORD DigitalIn;
DigitalIn=inport(BaseAddr);
return DigitalIn;
}
void P8R8_DO(WORD BaseAddr, WORD wOutData)
{
outportb(BaseAddr,wOutData);
}
UCHAR P8R8_DI(WORD BaseAddr)
{
UCHAR DigitalIn;
DigitalIn=inportb(BaseAddr);
return DigitalIn;
}
