RS-232 to RS-422 with video interrupt 
ANC-6022 Adapter
 RS-232/RS-422 Adapter with Video Sync Interrupt

 Providing the designer with a low cost solution to change RS-232C level transmit and receive signals into RS-422 differential level noise immune signals and a video sync interrupt for multimedia applications.

  • Transmit data at distances up to 4,000 feet (1,219 m)
  • Master/Slave Jumper selectable and Full Duplex operation
  • Plugs into DB-9 PC serial comport
  • Pin connections on RS485/422 side mate directly to many multimedia units (Sony, BTS, Grass Valley, etc.)
  • Baud rates to 115.2 KBaud
  • NTSC or PAL video input for interrupt generation on vertical sync
  • Frame accurate streaming video encoding (Windows Media Player)
  • Latest Surface Mount Technology (SMT) for low power and small size
  • ANC-6090 same adapter, without video input interrupt
Noise Immune Interface
 The adapter converts the RS-232C level signals transmit and receive on a PC into bipolar RS-422 type signals.  These converters find wide use in high-speed long distance serial communications, or to interface a PC with equipment that uses an RS-422 type input/output.  Extended cable runs, or terminated connections, require more current than the serial port power can provide so the RS-422 connector or on-board barrel connector can accept +4v to +12v DC at 100 milliamps to provide the added power to operate the adapter.

Interrupt for Vertical Video Sync
  Video multimedia applications sometimes require synchronizing the process with the vertical sync.   Like converting video to streaming video, and in MIDI applications for sound synchronization.   The ANC-6022 provides a BNC connector which allows the designer to input NTSC, or PAL, RS170 level composite or striped video.   The on-board sync separator produces an interrupt upon detection of a vertical sync pulse which is readable on the serial port's Data Carrier Detect (DCD, refered to as RLSD on some systems) or Ring Indicator (RI) line.   The designer can further input the serial port's status register to determine if the interrupt was generated by field 1 or field 2.   This feature is unique to the Antona ANC-6022 adapter.

Software Compatibility
 Because the adapter just converts RS-232C to and from RS-422 level signals, no specific software modifications are required to operate the adapter with off-the-shelf applications that use the serial communications port.  See our ANC-6090 adapter for the same RS-232C to RS422 or RS-485 conversion without the video interrupt.

Easy to Use
 Shipped ready for installation. Jumpers are pre installed for the most commonly applied  configuration and a comprehensive user's manual is included.

 Every Antona product is built and tested to meet high standards of quality and reliability.  Our products are covered with a one year warranty.
