The TRX-232A is an
8-channel RS-232 Buffer, also configurable as a dual 4-channel
Buffer. It is specifically designed to buffer RS-232C
signals that drive multiple loads, such as GPS receiver outputs,
or convert portable GPS receiver outputs to legitimate and
reliable RS-232C compliant signals.
Buffering of RS-232
signals increases system reliability by boosting the noise
immunity of serial data lines that are excessively loaded or are
not designed to drive multiple loads.
The TRX-232A also provides redundant diode-isolated power
supplies and grounds, thus avoiding single-point failures caused
by blown fuses or tripped circuit breakers.
