3.4.8 Printer port
The printer port is one of the two parallel ports. This interface, hereafter designated
LPT1, is a standard printer port in the form of a 25-pin Subm-D adapter connector
(female).
3.4.9 TRAM-NET interface (Microlab only)
9-pin connector (male) for communication with the Tram-Rac.
3.4.10 Analog output (optional)
Analog ECG output specifications:
Signal: lead 2 without PACE pulse
Gain: 1V/mV
Max. amplitude: +- 10V
Max. output current: +- 5mA at 2 kohm
Normal precision: Offset: < 300mV (full scale), gain < 3%
Voltage stability:> 1.5kV
Max. frequency: 100Hz
As from CardioSoft 3.0 and CORINA software version 3.0 the lead can be selected as
required (without PACE pulse)!
When connecting up a peripheral make sure that this instrument has an input low pass
of < 400Hz. If this is not the case, a (passive) low pass should be installed in the input of
the peripheral (Important: do not change the signal level!).
