Bay Technical Associates 525H 사용자 설명서
The BayTech H-Series multiport controllers are flexible, multi-function
data acquisition and control units that provide cost effective data
communications for applications that require control of multiple
peripherals from a single host computer. Designed with flexibility in
mind, the H-Series controllers can be programmed to provide full
duplex communication between host and peripheral or can provide
real-time data acquisition from remote peripherals. In a typical
application, the host port may be connected to such devices as bar
code readers, cash registers, fire alarms, numerical machines,
modems, plotters, printers, security systems, and terminals.

The host computer system may individually select up to seventeen
peripheral devices and send data to the selected device. The 525H
interfaces four peripheral devices to a single host device, the 528H
and 529H interface eight peripherals, and the 5218H interfaces
seventeen peripherals. All H-Series models will simultaneously
multiplex incoming data from peripheral devices to be transmitted to
the host system. The method of data transmission from the
peripheral devices to the host system is dependent upon the mode of
operation.

The H-Series models feature six user-selectable modes of operation.
The six modes of operation are:
The six modes of operation are:
Mode 1
Full Duplex Communication - Allows a single host
computer to switch between a maximum of seventeen
peripheral devices. Provides bidirectional data transfer
between the host computer and the selected peripheral
device. Data received from non-selected peripheral
devices is stored in a buffer until the port is selected.

Mode 2
All messages from all ports - Provides automatic
multiplexing of all messages from all peripheral devices.
Data is buffered until a terminating character is received
or until the buffer fills. The messages are then sent to
the host device preceded by a port identification code.
