PFM-42V1
Control-S Cable
Some older versions of the PFM-42V1 may require a different Control-S cable for proper IR
Sensor control between the Plasma and EBS-SP10. These units can be identified by serial
number:
Requiring Alternative Cable: PFM-42V1 Black S/N range 6500096 – 6501640
PFM-42V1 Silver S/N range 6535103 – 6539111
A standard stereo mini-jack audio cable used for PC audio can be used for this Control-S cable
6 LED functions
The two LEDs located on the SP-Tune indicate the current state of SP-TUNE and may be useful for
troubleshooting.
During the startup (after powering on) the LEDs blink as the unit goes through self-test procedures
and firmware booting. If, after connecting the power, LEDs do not show any activity, then probably there
are problems with the power supply.
If the LEDs blink in alternative pattern -- upper/lower/upper/lower/etc – then the bootblock is active
and no valid main firmware is detected. This can happen if, for instance, the preceding firmware update
procedure was aborted for some reason. The bootblock waits for the new firmware upload, see the
“Firmware update” section of this document.
During the normal functioning of SP-TUNE (when a valid firmware is loaded and self-test and
startup procedures are finished, which takes about 2 seconds), the LED functions are:
Upper LED:
• Flashes for 50ms once in 6 seconds when SP-TUNE is attached to power supply, but
is in “Power Off” (“sleep”) state. Flashes for 50ms once in 3 seconds when SP-
TUNE is in “Power On” state. This activity can be overridden by other activities of
the same LED.
• Blinks fast when IR signal are detected. This can be used to see whether SP-TUNE
receives any IR control packets or not. This does not mean that SP-TUNE recognizes
any IR command.
Lower LED:
• Switches ON when a control packet is sent to Sony Display Panel through RS-232.
Switched OFF when a valid reply to the control packet is received back. Therefore, if
this LED is ON for a long time, probably there are problems with the Panel
Connection (or Panel power supply).
The upper LED has also another purpose – if the SP-TUNE encounters an internal irrecoverable
error, it stops all activities and starts blinking the upper LED in series (series of blinks, then a longer
delay, then the series of blinks is repeated, so on).
