The ACB-MP+4.PCI (Item# 5402) is a four-port PCI bus RS-232, RS-422, RS-485
synchronous serial interface. Designed using the popular Zilog Z85230 Enhanced
Serial Communication Controller (ESCC), the board is an ideal solution for military,
satellite, radar, banking, and other applications that require robust synchronous
communications.
For maximum flexibility, each of the serial ports can be individually configured for
RS-232, RS-422, or RS-485 communications. In RS-232 mode, all common modem
control signals are implemented for compatibility with a wide range of peripherals.
A digital phase lock loop (DPLL) is included on each port, and the board supports
data rates up to 128K bps in burst mode. For easy implementation, a fan-out cable is
included that terminates the onboard 120-pin high-density Molex connector to four
DB-25M connectors.
The ACB-MP+4.PCI features Universal Bus (3.3V and 5V) compatibility with both
new and legacy computer systems. Software support, critical for successful
synchronous communication development, is provided through Sealevel’s SeaMAC
V4 driver. HDLC/SDLC protocols are supported as well as certain configurations of
Monosync, Bi-sync, and Raw modes.
The ACB-MB+4.PCI also utilizes the Sipex-505 multi-protocol electrical interface
chip that allows the ACB-MB+4.PCI to be compliant with EIA/TIA-530/530A,
EIA/TIA-232E, EIA/TIA-485, and ITU V.35. Optional cables are available to
connect RS-449, RS-530, RS-530A, V.35 and X.21 interfaces.
The ACB-MB+4.PCI is shipped with the following items. If any of these items is
missing or damaged please contact Sealevel for replacement.
Item# 5402 – ACB-MB+4.PCI Adapter
Item# CA339 – 120-Pin Molex to (4) DB25M Breakout Cable, 36” in Length
Item# SSI-CD – Sealevel Software CD with SeaMAC drivers
Optional Items
Depending upon your application, you are likely to find one or more of the following
items useful for interfacing the ACB-MB+4.PCI to real-world signals. All items can
be purchased from our website (http://www.sealevel.com
4343.
CA104 – A 6’ serial extension cable with one DB-25 female connector and one
DB-25 male connector, pinned one-to-one.
CA107 – a 10” shielded cabling adapter with a DB-25F (RS-530) to a DB-37M
(RS-449 DTE). RS-530 is replacing RS-449 in Telecom applications, but there is
still a very large installed base of equipment that still uses the RS-449 pin-out.
Both standards use RS-422 to define the electrical specifications and are
interchangeable via this adapter cable.
CA159 – A 6’ shielded cable with a DB-25 female connector (RS-530 pin out) to
a DB-15 male connector (X.21 pin out) that converts the standard DB-25
implementation of RS-530 or RS-422 to the ITU-T X.21 standard.
CA174 – A 6’ serial extension cable with twisted data pairs for increased data
integrity. Recommended for high-speed RS-530 connections.
CA178 – A 6’ shielded cable with a DB-25 female connector to an ITU-T ISO-
2593 style connector (V.35) that converts the Sealevel DB-25 implementation to
the ITU-T V.35 mechanical standard.
Do not install the adapter in the machine until the software has been fully
installed.
Note: SeaMAC V4 is only supported under Windows 2000/XP
1. Start Windows.
2. Insert the Sealevel Systems CD in your CD drive.
3. If ‘Auto-Start’ is enabled for this drive the software will automatically launch.
Otherwise launch the ‘autorun.exe’ file located in the root directory of the CD.
4. Click the ‘Install’ button.
5. Type in or select the part number for the adapter from the listing.
6. The setup files will automatically detect the operating environment and install the
proper components. Follow the information presented on the screens that follow.
7. IN Windows XP, a screen may appear with the declaration: “The publisher
cannot be determined due to the problems below: Authenticode signature not
found.” Please click the ‘Yes’ button and proceed with the installation. This
declaration simply means that the operating system is not aware of the driver
being loaded. It will not cause any harm to your system.
8. During setup, the user may specify installation directories and other preferred
configurations. This program also adds entries to the system registry that are
necessary for specifying the operating parameters for each driver. An uninstall
option is also included to remove all registry/INI file entries from the system.
9. The software is now installed and you can proceed with the hardware
installation.
