CONNECTING THE THINKJET PRINTER

The ThinkJet printer with an RS-232 serial interface (model
2225D) may be used to print the contents of the trend and
event memories, as well as to record ongoing saturation, pulse
rate, pulse amplitude, and monitor status.
Connect the ThinkJet printer to the N-200 as follows:
1. Set the N-200's baud rate to 19.2 K using the baud rate
switches: 7 and 8 up.
2. Set the N-200 format using the RS-232 format switches:
3–4 up, 5 down (Graphics Mode I); or to another desired
format.
3. Set the printer's MODE SELECTION switches: 1–5 down,
6 up, 7–8 down.
4. Set the printer's RS-232 switches: 1 up, 2–4 down, 5up.
5. Connect the printer to the N-200 using the interface cable
provided by Nellcor with the ThinkJet printer.
WARNING: Provide the ThinkJet with isolated power. If
isolated power is not incorporated in the ThinkJet, use
a standalone isolation transformer.
6. Provide isolated power (if appropriate), turn on the printer,
verify proper operation, and position the paper to start
printing near the top of the page.

If the printer's switch settings are changed while
it is turned on, it must be turned off and back on
again to implement those changes.
