Ideal for connecting a variety of serial devices to a computer using a USB port.
User set to interface as an RS232 (Pc comport), RS422 4-wire interface, RS485 2-wire interface or TTL low level interface.
  The adapter plugs into an internal motherboard IDC USB port, and works like a serial interface.   The user should insure that the motherboard being used has a board mounted 4-pin IDC USB jack.

• USB programmable 128 byte EEROM
• 300 baud to 3 Mbaud user programmable range (1Mbaud limit for RS232 operation)

Hardware Specifications

Mechanical/Connectors

• 1 foot USB 4-pin IDC cable
• Male DB9 for PC RS-232 serial comport operation
• Female DB9 for SMPTE RS485/422 and TTL interfacing

Electrical Specifications

• Voltage: +5v from USB port
• Current: 100 ma for long and/or terminated cable applications
• RS-485/422 output drive: short proof output, non-terminated operation to 150 feet, terminated operation to 4,000 feet.
• RS232 output drive: short proof output, under worse case conditions, 5v switching to exceed 3v EIA RS232 specification

Software Driver

The converter runs under Windows 98, 98SE, ME, 2000, XP, 2003, VISTA, Linux 2.4 & Linux 2.6.9 and later, FreeBSD 6.0 & MAC OSX.   Linux 2.6.9 and later, FreeBSD 6.0 and MAC OSX directly support the ANC-6204 without installing drivers.
