1. HT-180
Handshake Tester
for

2. HT-180 – Current Status Built on the technology of our 882 HDCP
compliance test feature – the worlds first and only
commercially available HDCP Compliance Test
application.
Troubleshoots HDCP, HPD and EDID interoperability
problems and helps identify problems.
Provides both up-steam and down-stream views of
HDMI component interactions.
Enhanced localization features anticipated
-- LCD display with error code reporting
-- Save “Trace” Files

3. HT-180 – What does it do? Assists in the troubleshooting of HDMI
Interoperability and handshake problems
Identifies 5V, Current and Hot Plug Issues
Identifies EDID problems
Localizes HDCP handshake problems

4. HT-180 – Typical root causes
EDID Failures
-Checks if EDID port was not acknowledged
-Checks if EDID port access was attempted by source
-Verifies that EDID header and checksums are valid
-Checks if EDID read was triggered by hot plug detection
Hot Plug Failures
-Checks hot plug for < 100ms deassertion
-Verifies that hot plug downstream assertion is passed to upstream
-Checks if hot plug detection assertion upstream was not the result of downstream problem
-Measures +5v signals for voltage and current draw on a source
HDCP Failures
-Checks for invalid Aksv from source
-Verifies that source write of An occurs prior to write of Aksv
-Verifies that source read of Bcaps occurs prior to read of R0’
-Verifies that source write of Aksv occurs prior to read of R0’
-Checks for invalid Bksv from sink
-Checks if Ri’ is read without second phase of authentication (in case of repeater)
-Checks if HDCP reauthentication was triggered by hot plug detection
-Checks if HDCP port is not acknowledged
-Checks for excessive HDCP re-authentication attempts by source
-Verifies that source attempted to access sink HDCP port
-Checks if the READY bit is not set as a result of any of the following failure conditions:
Repeater did not attempt to read Bksv downstream receiver
Source did not begin reauthentication after five seconds
Invalid Bksv

5. HT-180 – Operation
HT-180 is inserted in an HDMI system. The product will test up to
Three different devices for interoperability problems by displaying
Error codes on the LCD as well as in HTML trace files.

6. HT-180 – Operation Set up a trace using Immediate evaluation on
displayed on the LCD
Set up a trace using
the trace file capture software
Running on a connected PC

7. HT-180 – Operation
Ticket No.
Customer Info
Products!!
System
Captured trace files allow system information to be sent to a lab for
analysis. Each trace can specifically identify the components of the
system tested, date and location.

8. HT-180 – Enhanced failure indication (DDC Protocol Traces)
Reason & action codes
-Digests DDC protocol
data
-Provides root cause code
-Documentation provides
corrective action
DDC protocol traces
-USB captures DDC
data
-Customer service call
card with documentation
associates activity with
DDC trace files

9. HT-180 – Enhanced failure indication (reason & action codes)
Error Codes are shown on
the LCD, indicating more
precise failure mode and
referring to a list of causes
as well as possible solutions.
Additionally, an “A”, “B” or
“C” rating can suggest
Severity of the diagnosis.
