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.
1.0 GENERAL INFORMATION
The Industrial I/O Pack (IP) Series IP511 module provides four
isolated EIA/TIA-422B serial communication ports for interfacing to the
VMEbus or ISAbus, according to your carrier board. This module
implements full-duplex EIA/TIA-422B and includes four isolated data
paths for Transmit and Receive (Tx
±
& Rx
±
). Four units may be
mounted on a carrier board to provide up to 16 asynchronous serial
ports per system slot. For non-isolated requirements, refer to Acromag
Model IP501 (the non-isolated companion to this model).
The transmit and receive paths of each channel on IP511-16 units
include generous 16-byte FIFO buffers to minimize CPU interaction.
Model IP511-64 units utilize 64-byte FIFO buffers and include software
flow controls. 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 IP511
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 IP511 FEATURES
•
High Density - Provides programmable control of four isolated
EIA/TIA-422B serial I/O ports. Four units mounted on a carrier
board provide 16 serial channels in a single VMEbus or ISAbus
(PC/AT) system slot.
•
High-Voltage Isolation -
This module provides four
independently isolated serial ports protected for voltages up to
250VAC. This module will survive a 1000VAC dielectric strength
test for 1 minute without breakdown.
•
Large FIFO Buffers - Both the transmit and receive channels of
each serial port provide generous 16-character (Model IP511-16),
or 64-character (Model IP511-64) data buffering (plus 3 framing
bits per character). This gives the host CPU additional time to
process other applications and reduces CPU interactions and
interrupts.
•
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, 1.5, 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 -
provision 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.
