Introduction:
PCL-846/847 series cards provide four independent RS-422/485
serial ports on a card. Each port has a 16C550 UART with an on-chip
16-byte FIFO buffer for reliable, high-speed serial I/O. The UART
buffers data into 16-byte packets before putting it on the bus. This
drastically reduces the CPU load and avoids data loss when the
system is busy and cannot process the interrupt quickly. The UART
is especially useful for high speed serial I/O under Windows.
PCL-846 cards differ from PCL-847 cards in that they utilize
on-board optical isolators to protect your PC and equipment against
damage from ground loops, increasing system reliability in harsh
environments. To further increase reliability, PCL-846B/847B cards
include surge protection technology, protecting your system from
abrupt high voltage surges (up to 3000 V) such as those caused by
lightning during thunderstorms.
An RS-485 Network with Automatic Data Flow Control
Using RS-232 Software
The RS-485 mode automatically senses the direction of incoming
data and switches its transmission direction accordingly. This feature
makes your network look and act just like an RS-232 network.
Application software written for half duplex RS-232 can be used
without modification. Moreover, you can simply and quickly build an
RS-485 network with just two wires.

PCL-848A – IEEE-488 CONTROLLER
277,00 € Excl. VATAdd to cart-
General Information PCL-848A
- Introduction to the Product PCL-848A
The PCL-848A/B IPSE-488 interface card is a valuable addition to your PC that allows you to communicate with over 2000 products, made by over 200 manufacturers, in over 14 countries. The IEEE- 488-1978 standard that this IEEE-488 card implements is the most widely used international standard for information transfer between computer and electronic instruments. There are numerous publications and articles that may be used in conjunction with this manual to assist you to understand the interface standard. The IEEE reference document may be ordered by writing to the IEEE Service Center, 445 Hoes Lane, Piscataway, NJ 08854, USA.
The IEEE-488 interface card provides the hardware (electrical and mechanical) and software required for you to interface your PC to the IEEE-488 bus. The software is packaged in read-only-memory (firmware) to provide versatile and easy-to-use IEEE-488 function extensions for your current programming language or operating system. Firmware cannot be accidentally erased or overwritten and it is always available for use by application programs. This manual provided a programming reference (Section 3.) and programming techniques (Section 4. and 5.) to assist you in writing your own application programs.
The key features of this interface card include (PCL-848A) :
Operating in one of the two modes (switch selectable).
Mode A : Compatible with PCL-748 and use the on-board firmware driver.
Mode N : Software compatible with National Instrument PC-II and IBM-PC GP-IB adaptor and use the driver and software developed for them.
- Implementation of the entire IEEE-488 PCL-848A
- Powerful and easy-to-use software command set. Fewer arguments and simple initialization.
- Software driver is in on-board firmware. Requires no additional disk operation when using BASIC or Turbo Pascal.
- On-board RAM for working space. No system memory space is needed for the IEEE-488 interface operation.
- Built-in 16 bit digital output port provides a convenient and economical solution for signal switching and digital control applications. The D/O port is compatible with the daughter boards: PCLD-785 Relay Output Board, PCLD-786 SSR & Relay Driver Board and PCL—789 Amplifier & Multiplexer Board.
- BASICA, BASIC compiler and Quick—BASIC are supported as
standard languages. C and Pascal language support packages
can he ordered separately as PCL-748—C and PCL—748-P. - The software can change the PC printer port to an IEEE-438
device. The PrtSc (print screen} key, all print statements,
word processing and spreadsheet programs that use printer
driver in BIOS can use IEEE—488 printers. - High speed direct memory access (DMA) with the ability to
handle 64K byte arrays.

PCL-731 – 48bit Digital I/O Card
131,00 € Excl. VATAdd to cartFeatures:
• 48 digital I/O lines
• Emulates 8255 PPI mode 0
• Buffered circuits for higher driving capacity than the 8255
• Interrupt handling
• Output status readback
• Pin compatible with Opto-22 I/O module racksIntroduction :
The PCL-731 offers 48 programmable digital I/O lines. Each port
emulates the operation of an 8255 Programmable Peripheral
Interface (PPI) chip in mode 0, but provides a higher driving capacity
than the 8255.
The card’s DIO ports are combined into 8-bit ports, six for the
PCL-731. You can configure each port individually by software for
either input or output. The card can directly interface with SSR
module carrier boards through a 50-pin Opto-22 compatible
connector.
The PCL-731 is a low-cost alternative of the PCL-722. Like the
PCL-722 it provides a readback feature which lets you monitor the
status of the output by reading back the output portApplications

PCL-721 – 32 Channel D/I Card
156,00 € Excl. VATAdd to cartIntroduction PCL-721 :
The PCL-721/723 is a 32/24-channel digital input card with independent
interrupt capabilities that allows the PCL-721/723 to work in the
background while the processor perform other jobs in the foreground. With
this feature, your system can do real-time Process monitoring without
polling its inputs, channel by channel.The PCL-721/723 has two modes: normal and interrupt. While it is set to
normal mode, the PCL-721/723 serves as a general purpose multi-channel
digital input card. However,if it is set to interrupt mode, then each channel
will generate an interrupt request to the PC, once the channel input has
changed.The 32digital input channels ofthe PCL-721 are divided into 4 groups. The
24 digital input channels of the PCL-723 are divided into 3 groups. Each
group handles8 digital input channels. There is a register that reflects the
interrupt status of each groups. Users can first read this register to check
which group caused the interrupt, then by reading the 8channels’ status of
that group, you can easily find which channel generated the interrupt. This
two-pass feature saves lot of time to determine which service routine should
be executed in your ISR (Interrupt Service Routine).The PCL-721/723 is easy to configure. No switch or jumper settings are
needed (except the I/O base address). The IRQ level, individual channel’s
trigger mode (rising or falling edge), and interrupt mask (enable or disable)
are all software programmable
