Connections: Auxiliary Output
The auxiliary output is a nonisolated signal input/output meant only for
connection to another medical device that is compliant with IEC 60101-1.
Connection to a noncompliant device could result in a safety risk by exceeding
current limits.
The auxiliary output connector provides an analog ECG waveform output. The
analog ECG waveform signal is a high level (1 V/mV) representation of the
primary lead. The connector is a two-conductor 3.5 mm stereo jack that mates
with a 3.5 mm stereo plug (Shogyo SPY 1011, Shogyo SPY 1012, or equivalent).
Cable construction should be shielded, three conductor with PVC insulation or
equivalent insulating material.
