Card Test

OPTOUSB Tester Card-Annotated-720pxV.jpg

  • Connect test card to UUT
    • Connect FTDI - black = ground
    • Does not require LEDs connections
    • Does not require 5V Power Supply (used for OPTOUSB card)
  • Test card
  • Plug in USB to computer
    • Should hear Windoze detect sound
    • Use Device Manager to determine which COM port is used
  • Run puTTY
    • Baud rate = 115,200 baud
    • Hardware handshake RTS/CTS
    • COM port from Device Manager
  • Jumper Settings - Normal operation
    • Left jumper in right position (loopback data)
    • Middle jumper in left position (handshake = active/ground)
    • Right jumper in right position (loopback handshake)
    • Type on keyboard and verify it returns data
    • Verify both LEDs on the card light
  • Jumper settings - Test Tx/Rx isolation
    • Move left jumper to left position
    • Type data nothing should come back (verify RX LED only lights)
    • Move left jumper to right position
  • Jumper settings - Test RTS/CTS
    • Move right jumper to left position (handshake controlled by middle jumper)
    • Type and characters should return
    • Move middle jumper to to right position (hardware handshake off)
    • Type and nothing should go through
    • Move middle jumper to to left position (hardware handshake on)
    • Characters that were buffered should come in at once
