Interface module for 20-m local bus (N-AT)
Description and ordering data
Fig. 4/8 Interface module for 20-m local bus (N-AT)
Application
The module is used to connect the following systems/devices to
the CS 275 bus system:
OS 520 operation and monitoring system
SICOMP industry-standard PC
HP 9000/7xx workstation
AT-compatible personal computer.
For adaptation to the bus communication, a coupling software
must be installed in these devices (except of OS 520 sys-
tem).The interface module N-AT handles duties specifically con-
nected with data transmission, including occasional control of
data transfer.
Design
Plug-in card in long AT format with one plug on the front panel.
Slot: extension slot in AT format in the above-mentioned
devices.
The interface module N-AT contains:
An SAB 80 188 microprocessor for controlling and monitoring
all functions
A dual-por t RAM system interface to the AT bus with asso-
ciated control logic
An interface to the 20-m local bus with bus interface logic.
Mode of operation
Data received via the CS 275 bus system pass through the line
protocol controller of the bus interface logic in bit-serial mode
and are placed into intermediate storage. The microprocessor
reads the data byte-by-byte and stores them in the buffer
memory of the module.
As soon as sufficient space is available in the dual-port RAM for
a complete message, this is entered into the receiver order list
of the dual-port RAM. Transmit messages are transferred from
the coupling software to the dual-port RAM system interface
and entered into the transmitter order list.
