PNLG-3324(E) series SDI/YUV/RGB/PAL/SECAM/YC=>SDI/YUV/PAL/SECAM/YC logo-mixer and synchronizer

PROFLEX™ PNLG-3324(E) series logo-mixer and synchronizer accepts the SDI/YUV/RGB/PAL/SECAM/YC (625/50) video signals, converts into the SDI/YUV/PAL/SECAM/YC (625/50) standards video, generates and inserts the LOGO and/or scrolling text video into the output signal with the synchronization to external REF reference video.

Two modifications exist:

  • PNLG-3324 – with RS-232 interface;
  • PNLG-3324E – with Ethernet network connectivity.

The PNLG-3324 module occupies two slots in a PROFLEX rack.

Controls:

  • MODE - toggles through all the modes,
  • UP and DOWN buttons edit them

Press the DOWN and UP buttons simultaneously to reset a parameter to it's default value.

  • CL – toggles the scrolling text/line mode ON/OFF

Indicators:

At the frontal edge of the board the two status LEDs are located:

  • INP – lit when an input signal is present
  • REF – lit when the REF signal is present (if synchroniser is enabled)

The main indication board contains:

  • OPTION – lit when the main seven-segment LED dispalys whether the LOGO or synchronizer parameters are being preset

The standard converter's/synchroniser's controls menu

  • INP – lit when the input mode (SDI, CCVS 1, CCVS 2, YUV , RGB , Y/C) is being selected with the DOWN/UP buttons. The modes are shown at the main LED as SDI – SdI, YUV – YUu, RGB – rGb, Y/C – YC respectively. The CCVS 1 or CCVS 2 input mode is displayed as PAL or SECAM, autodetectable by the decoder as follows:
    • 1 SE – the SECAM signal is present at the CCVS 1 input
    • 1 PL – the PAL signal is present at the CCVS 1 input
    • 2 SE – the SECAM signal is present at the CCVS 2 input
    • 2 PL – the PAL signal is present at the CCVS 2 input
  • OUT – lit when the output mode (SDI, CCVS 1, CCVS 2, YUV , RGB , Y/C) is being selected with the DOWN/UP buttons. The modes are shown at the main LED as SDI – SdI, YUV – YUu, PAL – PAL, SECAM – SEC, Y/C – YC respectively.
  • BLCK ( BLACK ) – is lit when the LUMA's channel black level is being adjusted (in the ± 70mV range) with the DOWN/UP buttons. The level is shown as ±99 points. In the SDI mode is not available.
  • CHR ( CHROMA ) – is lit when the saturation level is being adjusted (in the +5...-13dB range) with the DOWN/UP buttons. The level is shown as ±99 points. In the SDI mode is not available.
  • GAIN – lit when the LUMA gain is being adjusted (in the +1.8...-2.5dB range) with the DOWN/UP buttons. The level is shown as ±32 points. In the SDI mode is not available.
  • TIME H and TIME V – lit when the timing of the output signal is being adjusted relative to the REF video (H – within a TV line, ±32µs range, V – within a TV frame, ±99 TV lines). (if synchroniser is enabled)
  • SC – lit when the PAL/YC subcarrier phase is being adjusted within the 360° range (except the PNLG-3324). The YUV mode: depending on the S1.6 DIP switch setting - the Y output H-sync puls timing may be adjusted within (+7...-8)* 74ns range, depending on the S1.5 DIP switch setting - the Y output H-blancing puls timing may be adjusted within (+7...-8)* 74ns range
