Description
RS Mode
(
RocketPort
EXPRESS/INFINITY
)
Use this drop-down list to select the communications mode
for the serial device that you will be connecting to this port.
•
RS-232 (default RocketPort EXPRESS, RocketPort
INFINITY, RocketPort Universal PCI, RocketPort Plus
Universal PCI, and RocketModem IV)
•
RS-422 (default RocketPort EXPRESS SMPTE,
RocketPort Plus/422 Universal PCI, and RocketPort
Universal PCI SMPTE)
•
RS-485 Mode provides these choices:
-
RS-485 2-wire (half-duplex) supports transmit and
receive data. When data is transmitted, the
Transmit Enable signal is activated, and the
Transmit Receive device switches from receive to
transmit automatically.
-
RS-485 4-wire Master (full-duplex master) supports
transmit and receive data, which means both
signals are always active. The RocketPort
EXPRESS/INFINITY is enabled by the Transmit
Enable signal. This mode is the same as RS-422.
-
RS-485 4-wire Slave (full-duplex slave) supports
transmit and receive data. When data is
transmitted, the Transmit Enable signal is
activated, the Transmit device goes active and
starts sending data. When the data is not being
sent, the Transmit device is inactive. The Receive
device is always active.
If you click RS-485, you may need to change settings in the
screen.
The default value is RS-232 for most RocketPort EXPRESS/
INFINITY models. The RocketPort EXPRESS SMPTE
default value is RS-422.
Note: The RocketPort/RocketModem (Universal PCI) RS
Mode is controlled by the attached interface.
