500 SERIES MULTIPORT CONTROLLERS
Included in the
500 Series
line of multiport controllers are units
intended for the following applications:
Port Expansion (A-Series):
Allows a single serial port on a
computer to individually access up to 17 peripheral devices with full
duplex communication.
Single Port Contention (DQ-Series):
Allows up to 17 terminals to
contend for a single port on a computer system.
Multiple Port Contention (B-Series):
Allows either 6, 8 or 12
terminals to contend for either 3, 4 or 6 computer ports respectively.
Networking (F-Series):
Networks either 5 or 9 ports together, i.e.,
allows any port to connect to any other port on the multiport controller.
These also have host port control which allows a host computer
system to make and/or break any connection between two ports on
the multiport controller.
Broadcasting (G-Series):
Will simultaneously broadcast whatever
data is received on the host port out to either 4 or 8 peripheral devices
while sending data from a single selected peripheral device back to
the host device. This unit is also capable of operating in a port
expansion mode such as the
A-Series
.
Auto T-Switch (T-Series):
Allows a group of up to 6 terminals to
switch between two computer systems.
NOTE:
All ports on the
500 Series
are standard with EIA-232 ports.
EIA-422 and Current Loop ports are optionally available.
