Main / LOGO generator-inserters / PNLG-3321
PNLG-3321(E) series SDI/YUV/RGB/PAL/SECAM/YC=>PAL/SECAM/YC logo-mixer and synchronizer |
PROFLEX™ PNLG-3321(E) series logo-mixer and synchronizer accepts the SDI/YUV/RGB/PAL/SECAM/YC (625/50) video signals, converts into the 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.
The PNLG-3321 module occupies two slots in a PROFLEX rack.

PNLG-3321 controls and indicators
PNLG-3321 consists of the two submodules: the frontal one, with all the controls and indicators, and the rear one, with all the connectivity means.
PNLG-3321 rear panel view
PNLG-3321 frontal panel view
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, CCVS1, CCVS1, Y/C) is being selected with the DOWN/UP buttons. The modes are shown at the main LED as SDI – SdI, Y/C – YC respectively.
- 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
- VBI – lit when the VBI-pass-through options are preset (teletext, VITC, etc):
- PAS – VBI pass-through is ENABLED
- BLA – VBI contents is blanced
- REF – VBI contents is being transferred from the REF video into the output signal
- VITS – not implemented in the PNLG-3324
- TEST – lit when a test signal type is being selected for the frame's active lines:
- oFF - test signals are OFF
- brh - vertical color bars
- bru - horizontal color bars
- L 1, L 2, L 3, L 4 - the I , II , III , IV test-signals (according to GOST 18471-83)
VITS number (according to the GOST 18471-83) is being shown on the main indicators.
The LOGO/scrolling texts controls menu
(on the gray-shaded markers)
- YEAR – lit when the calender year value is being preset
- MON – lit when the calender month value is being preset
- DATE – lit when the calender day value is being preset
- HOUR – lit when the clock hour value is being preset
- MIN – lit when the clock minute value is being preset
- L ON – displays the ON/OFF status of the preselected LOGO-scene at the program output
- L SEL – lit when the scene number is being selecter
- CL RUN – lit when the scrolling text is enabled
- CL ON – displays the ON/OFF status of the preselected scrolling line at the program output
- CL SEL –lit when the scrolling text sample number is being selected
- CL SET – displays the number of the preselected scrolling line
All the settings are stored in a non-volatile memory.
The remote control and management from a PC
All the PROFLEX™ modules are remote controllable from a PC. This facility is available if a rack is fitted with a CPU module (ordered separately).
