Operating States

The HMIA has the following operating states: Start-up and Run.

Start-up

When the console is powered on, illumination of the Green LED is indication that power has been supplied to
the HMIA. If there is no power to the HMIA the Green LED is not lit and the hospital monitor, if attached to the
HMIA, should detect this as a probe disconnection or temperature probe error.

Once powered, the HMIA immediately establishes its link with the console and performs a series of self tests
including self-calibration – see below.

Run

The HMIA is designed to provide a variable resistance value that is interpreted by YSI-400 compliant hospital
monitors as patient temperature. The patient temperature is obtained via the T1 connection of the console.

Calibration

HMIA performs a self-calibration at Start-up. It will also perform a self-calibration upon reconnection of the RS-
232 port (for example, you might temporarily disconnect the HMIA to allow access for data download). Self-
calibration takes less than half a second. During self-calibration, it may be detected by the hospital monitor as
a disconnected probe. At the end of self-calibration the HMIA will automatically return to Run.

Function

RST

Reset Button

This is a reset button. Lightly push the tip of a
paper clip, or similar sized device, into the hole
until you feel a “click” and then withdraw the
paper clip.

Caution LED

This red light indicates that there is a malfunc-
tion in the HMIA.

Power LED

This green light indicates that the HMIA is
receiving power from the console.

RS232

RS-232 Serial port connector
cable

This short extension cable is connected to the
RS-232 data port connector on the back of the
display head.

T1 out

Patient temperature output
connector

This connector accepts the custom ZOLL inter-
face cable.

SYSTEM

Console umbilical cord connec-
tions

One connector is attached to the round, multi-
pin connector on the back of the display head
via a short cable. The other connector mates
with the umbilical cord of the console.
