IMPORTANT SAFETY CONSIDERATIONS
It is very important for the user to consider the possible adverse
effects of power, wiring, component, sensor, or software failures
in designing any type of control or monitoring system. This is
especially important where economic property loss or human life
is involved. It is important that the user employ satisfactory
overall system design. It is agreed between the Buyer and
Acromag, that this is the Buyer's responsibility
10 GENERAL INFORMATION
The Industrial I/O Pack (IP) Series IP503 module provides
two EIA/TIA-232E serial communication ports and a bi-directional
Centronics parallel port for interfacing to the VMEbus or ISAbus,
according to your carrier board. Four units may be mounted on a
carrier board to provide up to 8 asynchronous serial ports, plus 4
Centronics parallel ports per system slot
The transmit and receive paths of each channel include
generous 16-byte FIFO buffers to minimize CPU interaction. Full
EIA/TIA-232E DB-9 signal support for dial-up and modem control
is included. Character size, stop bits, parity, and baud rate are
software configurable. Prioritized interrupt generation is also
supported for transmit, receive, line status, and data set
conditions. The IP503 utilizes state of the art Surface-Mounted
Technology (SMT) to achieve its wide functionality and is an ideal
choice for a wide range of industrial communication interface
applications that require a highly reliable, high-performance
interface at a low cost
KEY IP503 FEATURES
•
High Density - Provides programmable control of two
EIA/TIA-232E serial ports and one Centronics parallel port.
Four units mounted on a carrier board provide 8 serial
channels, plus 4 parallel ports, in a single VMEbus or
ISAbus (PC/AT) system slot
•
16-Character FIFO Buffers - Both the transmit and receive
channels of each serial port provide 16-byte data buffering
(plus 3 framing bits per byte) to reduce CPU interactions
•
Centronics Parallel Port - A bi-directional Centronics
parallel port is included for communicating with printers and
other devices
•
Programmable Character Size - Each serial port is
software programmable for 5, 6, 7, or 8 bit character sizes
•
Programmable Stop Bits - Each serial port allows 1, 1-1/2,
or 2 stop-bits to be added to, or deleted from, the serial data
stream
•
Programmable Parity Generation & Detection - Even,
Odd, or No Parity generation and detection is supported
•
Line-Break Generation & Detection - provisions for
sending and detecting the line break character is provided
•
False Start Bit Detection - Prevents the receiver from
assembling false data characters due to low-going noise
spikes on the RxD input line
•
Programmable Baud Rate - The internal baud rate
generator allows the 8MHz clock to be divided by any divisor
between 1 and 2
(16-1)
, providing support for any bit rate up to
128Kbps
•
Individual Modem Control Signals - Each serial channel
includes a modem-control and modem-status register and
provides full EIA/TIA-232E modem line support, including
RTS, CTS, DTR, DSR, DCD, and RI
