at the serial port of the primary receiver will be forwarded to the transmitter and made available to
the source device through its serial port. Thus, bidirectional serial transfers can be exchanged only
between the devices connected to the transmitter and primary receiver. Unidirectional serial
communication, from the transmitter, is made available to all receivers.
Serial passthrough mode is enabled via the web interface of an MPX1000 transmitter. Serial port
settings, such as baud rate, flow control, data size, top bits and parity are also configurable only via
the transmitter’s web interface. When serial passthrough is enabled, this configuration information
is forwarded to all receiver units within the extender network. When serial mode is disabled, there
is no processing of serial data on either the transmitter or the receiver(s).
Serial settings on all source and display devices must correspond with the serial settings established
via the web interface on the transmitter.
In summary, serial operation of the product is as follows:
• If serial passthrough is enabled, then data received at the serial port of the transmitter will be
broadcast through the extension network to all bound receivers and, in turn, to all serially
attached display devices.
• If serial passthrough is disabled, then serial data received at the serial port on the transmitter
will be ignored.
• If a primary receiver is selected via the web interface on the transmitter, then data received
from the device attached to the serial port of the primary receiver will be forwarded across the
extension network to the MPX1000 transmitter and, in turn, to the device attached to
transmitter’s serial port.
• If a primary receiver is not selected, then serial data will still be broadcast from the transmitter
to all bound receivers; however, bi-directional transfers will not be available.
• All serial settings must be made via the web interface on the transmitter. The web interface on
the receiver does not offer serial configuration options.
