Introduction
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 100-pin 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-MP+4.PCI also utilizes the Sipex-505 multi-protocol electrical interface
chip that allows the ACB-MP+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.
