Description of Equipment
PRN 50-M and PRN 50 Digital Writers
The PRN 50-M and PRN 50 Digital Writers thermally record patient
data on a paper strip. You can graph any parameter or trace you monitor
on a Solar 7000/8000/8000M monitor, Eagle 4000 monitor, Centralscope,
or CIC system on the the writer. Graphs are initiated automatically
when an alarm activates, or you can manually initiate a graph from a
monitor.
The writer provides a high-re solution recording of patient waveform
data, including alphanumeric text relating to the waveform data. A
microprocessor-driven thermal print head translates digitized data
directly into graphic forms on the strip chart. Up to four real-time
waveforms from the monitor scree n may be graphed simulta neously. The
writer also generates printouts of stored information, including trended
parameters, arrhythmia information, and cardiac calculations,
pulmonary calculations, and dose calculations.
The paper drive motor is the only moving part on the PRN 50-M. This
motor operates at eight different speeds—0.1, 0.5, 1, 5, 10, 12.5, 25, and
50 mm/s.

carriage door is open. If you press the *5$3+6723 switch while
graphing, the writer stops immediately. If you hold the switch down for
more than 10 seconds, an alphanumeric test strip prints out.

Interconnection
M-Port/AutoPort Compatibility
1. An M-Port Host/Device must be connected to an M-port Device/Host.
2. If an AutoPort Host/Device is to be connected to an M-Port Device/
Host, the AutoPort Host/Device must be adapted to an M-Port pin
out by using the AutoPort to M-Port Adapter.
127(
Whether a host or device implement s an M-Port or an AutoPort
interface can be determined by:
1. M-Port Host/Device products have any or all of the following:
a. Have the word ‘M-Port’ or ‘M#’ e.g., ‘M1’, ‘M2’, ‘M3’; for
the connector name on the label above the RJ-45.
b. Have the text for the name of the RJ-45 connector in a
yellow field.
c. Have a product name that ends in an ‘M’, e.g., Solar
8000M, PRN 50-M, Respiratory Mechanics-M.
2. AutoPort Host/Device products do not have any of the above.
