SERIES IP511 INDUSTRIAL I/O PACK ISOLATED QUAD EIA/TIA-422B COMMUNICATION MODULE
___________________________________________________________________________________________
- 3 -
•
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 512Kbps.
•
Port Power Jumpers Provided for Non-Isolated Mode
- For
isolated operation, the port connections must include external
is5V power. However, the IP +5V power supply may be
optionally jumpered to the port(s) for convenient non-isolated
operation.
•
Software Flow Control
- The IP511-64 includes support for
software flow control for more efficient data transfer.
•
Interrupt Support -
Individually controlled transmit, receive, line
status, data set, and flow control (IP511-64) interrupts may be
generated. Unique interrupt vectors may be assigned to each
port. Interrupt generation uses a priority shifting scheme based on
the last interrupt serviced, preventing the continuous interrupts of
one port from freezing out the interrupts of another port.
•
Socketed Termination Resistors
- The receiver of each port
includes a network termination resistor installed in a socket on the
board and these may be easily inserted or removed where
required.
•
Internal Diagnostic Capabilities
- Loopback controls for
communication link fault isolation are included. Break, parity,
overrun, and framing error simulation are also possible.
•
Industry Standard 16550 Family UART w/16C450 Mode
- The
UART of this device is a member of the industry standard 16550
family of UART’s and remains software compatible. Additionally,
this device can operate in a 16C450 UART family software
compatible mode. The transmit and receive channels are double-
buffered in this mode. Hold and shift registers eliminate the need
for precise synchronization between the host CPU and the serial
data.
INDUSTRIAL I/O PACK INTERFACE FEATURES
•
High density -
Single-size, industry standard, IP module footprint.
Four units mounted on a carrier board provide up to 16 serial ports
in a single system slot. Both VMEbus and ISAbus (PC/AT)
carriers are supported.
•
Local ID
- Each IP module has its own 8-bit ID PROM which is
accessed via data transfers in the "ID Read" space.
•
8-bit I/O
- Port register Read/Write is performed through 8-bit data
transfer cycles in the IP module I/O space.
•
High Speed
- Access times for all data transfer cycles are
described in terms of "wait" states - 2 wait states are required for
reading and writing channel data and interrupt select cycles. One
wait state is required for reading the ID PROM (see the
Specifications section for detailed information).
SIGNAL INTERFACE PRODUCTS
(See Appendix for more information on compatible products)
This IP module will mate directly to any industry standard IP carrier
board (including Acromag AVME9630/9660 3U/6U non-intelligent
VMEbus carrier boards). Additionally, ISAbus (PC/AT) carrier boards
are supported (see Acromag Model APC8600). A wide range of other
Acromag IP modules are also available to serve your signal conditioning
and interface needs.
Note:
Since all connections to field signals are made through the carrier
board which passes them to the individual IP modules, you should
consult the documentation of your carrier board to ensure compatibility
with the following interface products.
Cables:
Model 5025-551-X (Shielded Cable), or Model 5025-550-X (Non-
Shielded Cable): A Flat 50-pin cable with female connectors at
both ends for connecting AVME9630/9660, or other compatible
carrier boards, to Model 5025-552 termination panels. The
unshielded cable is recommended for digital I/O, while the shielded
cable is recommended for optimum performance with precision
analog I/O applications. The “-X” suffix of the model is used to
specify the required length in feet.
Model 5029-943 IP500 Serial Communication Cable: A 5 foot long,
flat 50-pin cable with a female connector on one end (for
connection to AVME9630/9660 or other compatible carrier boards)
and four DE-9P connectors (serial ports) on the other end. Also
used for interface with Acromag Model IP500 (EIA/TIA-232E),
IP501/IP511(EIA/TIA-422B), and IP502/512 (EIA-485) serial
communication modules.
Model 5029-900 APC8600 High-Density Cable: A 36-inch long
interface cable that mates the high-density (25mil pitch) 50-pin I/O
connectors of the APC8600 PCbus carrier board, to the high-
density connectors on the APC8600 Termination Panel (described
below).
Termination Panels:
Model 5025-552: A DIN-rail mountable panel that provides 50
screw terminals for universal field I/O termination. Connects to
Acromag AVME9630/9660, or other compatible carrier boards, via
flat 50-pin ribbon cable (Model 5025-550-X or 5025-551-X).
Model 5029-910 APC8600 High-Density-to-Screw-Terminal
Termination Panel: This panel converts the high-density ribbon-
cable connectors coming from the APC8600 carrier board
(Acromag cable Model 5029-900) to screw terminals, for direct-
wired interfaces.
Transition Module:
Model TRANS-GP: This module repeats field I/O connections of
IP modules A through D for rear exit from a VMEbus card cage. It
is available for use in card cages which provide rear exit for I/O
connections via transition modules (transition modules can only be
used in card cages specifically designed for them). It is a double-
height (6U), single-slot module with front panel hardware adhering
to the VMEbus mechanical dimensions, except for shorter printed
circuit board depth. It connects to Acromag Termination Panel
5025-552 from the rear of the card cage, and to AVME9630/9660
boards within the card cage, via flat 50-pin ribbon cable (cable
Model 5025-550 or 5025-551).
INDUSTRIAL I/O PACK SOFTWARE LIBRARY
Acromag provides an Industrial I/O Pack Software Library diskette
(Model IPSW-LIB-M03, MSDOS format) to simplify communication with
the board. Example software functions are provided for both ISAbus
(PC/AT) and VMEbus applications. All functions are written in the “C”
programming language and can be linked to your application. For more
details, refer to the “README.TXT” file in the root directory on the
diskette and the “INFO511.TXT” file in the appropriate “IP511”
subdirectory off of “\VMEIP” or “\PCIP”, according to your carrier.
