• RS-232/Probe - Should be connected to the HCITrace Probe Cable or to the
TTL to RS232 converter (depending whether the signal voltage in the IUT is
TTL or RS-232).
• COM A - Should be connected to one of the serial inputs of the 2-port RS232
to USB converter.
• COM B - Should be connected to one of the other serial input of the 2-port
RS232 to USB converter.
TTL to RS232 converter
Should be used only when the signal voltage in the IUT is TTL and not
RS-232.
The DB-9 connector marked with ‘TTL’ should be connected to the
HCITrace Probe Cable.
The DB-9 connector marked with ‘RS-232’ should be connected to the
'RS-232'/Probe connector of the HCITrace RS232 Cable.
2-port RS232 to USB converter -
This converter is used so the serial signals can be delivered to the host
machine through a USB input.
USB cable –
Connects the 2-port RS232 to USB converter to the Host machine USB
port.
HCI Probe configurations
The HCI Probe can be used in two configurations:
• For monitoring UART level signals
• For monitoring RS232 level signals
Monitoring UART Level Signals
For monitoring RS232 level signals, the TTL to RS-232 converter should be
used. To assemble the HCI probe for this configuration, perform the
following steps. Refer to the photo and component list shown previously
for references to components [a] through [e].
Step 1 Connect the DB-9 connector of the HCITrace Probe Cable
[a] to the connector marked with ‘TTL’ in the TTL to
RS-232 converter [c].
Step 2
Connect the DB-9 connector marked with ‘RS-232’ in the
TTL to RS-232 converter [c] to the connector marked with
‘'RS-232/Probe’’ in the HCITrace RS-232 Cable [b].
Step 3 Connect the connector marked with ‘COM A’ in the
