The interface boards provide the necessary circuitry required to
create a link between the parallel port of the SBC and the
following peripherals:
• Patient Data Card Reader
• Sodium Button pendant
• 3-Light status lamp
In addition to the parallel port interface, the interface boards also
provide an isolated RS-232 serial port to an external device and a
serial channel and power to the internal Non-Invasive Blood
Pressure Monitor (NIBP) subsystem.
Note
Interface of the SBC’s Ethernet to the rear panel outlet is achieved
through cabling. The Instrument interface boards are not involved
with this function. This feature is not yet available.
