10.2.1.1 TTL Configuration
1. TTL Pulse Duration:
1.1. Configure the duration of the TTL OUT (1-bit), 4-bit TTL OUT and Auxiliary TTL OUT.
The allowed range is: 50 – 1000 msec.
2. TTL Polarity:
2.1. TTL OUT: Configure the Polarity of TTL OUT pulse: 5V or (-)5V. For 5V: The TTL is 0V
when Idle and 5V when triggered. For (-)5V: The TTL is 5V when Idle and 0V when
triggered.
2.2. TTL IN: The polarity of the TTL IN does not need to be configured. Pathway will
automatically detect if it is 5V or (-)5V.
3. TTL Diagnostics: Manually generate a TTL OUT (1-bit), an Auxiliary TTL or 4-bit TTL word
to test the configuration. To test TTL-IN setup, send a TTL to the system and check of the
TTL-IN indicator turns on.

10.2.1.2 Enable \ Disable Thermodes
Enable or disable Thermodes according to the Thermodes currently connected to the system.
1. Thermodes are automatically disabled after updating the system firmware. The system
may also disable a Thermode if it detects that the Thermode may have been disconnected.
If the Thermode is connected to the system try to manually enable the Thermode by
selecting the checkbox.
2. If a Thermode is not connected to the system or is not in use, disable it by unselecting the
checkbox.
10.2.1.3 General Hardware Configurations:
Rest Temperature – The temperature of the Thermode when the system is in Rest Mode (not
running a test or in Safe Mode). The allowed range is 20-40 °C.
Warning! The parameters described below effect the performance of the
Thermodes. Medoc recommends not to change the default values unless
you are absolutely sure it is required
Ramp Timeout (% of duration) - If Ramp temperature continues to be detected beyond
this setting, an error message is displayed. The test is not aborted. Default value is 200%.
Peak Detection Delay (samples) – peak detection is used when a standard event of type
‘peak’ is used. This parameter can be adjusted if the timing of the event and the actual peak
are not synchronized. The default value is 30.
Dynamic Factor–this parameter is currently not in use.
Software Buzzer Enabled – the software buzzer informs the system operator of an
occurrence that requires his or her attention by sounding an alarm (computer speakers are
required). This safety measures enables the operator to be aware of the system status even
while not observing the screen. To enable or disable this option, select or unselect the
checkbox. Default option is enabled.
