For monitoring RS232 level signals do not use the TTL to RS-232
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

If you intend to connect the RS232 cable directly to a serial
port on your PC, do so now. You are now done.

If you are planning to link the probe to your PC via a USB
connection, perform the remaining steps.

Step 3

Connect ‘COM A’ in the RS-232 Cable [c] to ‘Connector A’
in the RS232 to USB converter [d].

Step 4

Connect ‘COM B’ in the RS-232 Cable [b] to ‘Connector B’ in
the RS232 to USB converter [d].

Step 5

Connect the USB cable to the RS232 to USB converter [e].

Step 6

Connect the other end of the USB cable to your PC.

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 PC, the converter emulates two separate virtual COM
ports that can be used as other real COM ports.

To connect the HCI probe to the host PC, you will need to install several
drivers. 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.
