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 HCITrace
RS-232 Cable [b] to ‘Connector A’ in the 2-port RS232 to USB
converter [d].

Step 4

Connect the connector marked with ‘COM B’ in the HCITrace
RS-232 Cable [b] to ‘Connector B’ in the 2-port RS232 to USB
converter [d].

Step 5

Connect the USB cable to the USB connector of the 2-port
RS232 to USB converter [e].
