37 pin D-SUB male connector diagram and applications

37 pin D-SUB male used in:

• DEC Printer 
• RS-449 (EIA-449) interface The RS449 interface is a generic connector specification. It´s not an actual interface. The connector pinning was originally designed to support RS422 for balanced signals, and RS423 for the unbalanced signals. And should have been the succesor of RS232.
• GeekPort The GeekPort is a connector available at Be´s BeBox computers. This is a dream for all hobby engineers who like to connect the computer to the coffee machine.
• RS232 to RS422 cable electrically isolated RS422 communication interface to the PC serial port
• RS-422 (EIA-422) serial interface RS422 is a balanced serial interface for the transmission of digital data. The advantage of a balanced signal is the greater immunity to noise. The EIA describes RS422 as a DTE to DCE interface for point-to-point connections.

  37 pin D-SUB female used in:
  
• DEC Printer 
• Paravision SX1 to IDE cable Can be used to connect a normal IDE harddisk to the Paravision SX1. Paravision was earlier known as Microbotics
• Paravision SX-1 External IDE Paravision was formerly Microbotics.
• Novell and Procomp External SCSI This interface is nowadays considered obsolete.
