[d] Two-Port RS-232 to USB Converter
For monitoring RS232 level signals do not use the converter. To assemble
the HCI probe for this configuration, perform the following steps:
Step 1 Connect the DB-9 connector of the HCITrace Probe Cable [a] to
the connector marked with ‘'RS-232/Probe’’ in the HCITrace
RS-232 Cable [b].
Step 2 Connect the connector marked with ‘COM A’ in the HCITrace
RS-232 Cable [c] to ‘Connector A’ in the 2-port RS232 to USB
converter [d].
Step 3 Connect the connector marked with ‘COM B’ in the
HCITrace RS-232 Cable [c] to ‘Connector B’ in the 2-port
RS232 to USB converter [d].
Step 4 Connect the USB cable [not shown] to the USB connector of the
2-port RS232 to USB converter [d].
2-port RS232 to USB converter
The 2-port RS232 to USB converter [d] allows the user to connect two serial
connectors to the host machine via a single USB connection. When
connected to the host machine the converter emulates two separate virtual
COM ports that can be used as other real COM ports. Prior of using this
converter as part of the HCI probe several drivers need to be installed. The
drivers are provided on the installation CD-ROM in the HCI Probe\Drivers
sub directory.
Once the converter is connected to a host machine the user is prompted to
provide the place where the system can install the drivers from.
