Headers/Jumpers/Connectors

5V/3.3V Jumper

• Select 5V or 3.3V signal levels on FTDI connector
• On FTDI connector VCC pin pin 3

(Inputs are 5V tolerant (when set to 3.3V levels)

FTDI Connector

• Right angle 1x6 pins

1. GND
2. CTSn (IN)
3. VCC
4. TX (OUT)
5. RX (IN)
6. RTSn (OUT)

USB Connector

• USB B Connector

Stackup with EP2 FPGA card

• Top to bottom of stackup

1. EP2C5-DB
2. Cyclone_II_EP2C5_Mini_Dev_Board Card
3. FTDI-49MM - (this card)

Card Test

• Connect OPTOUSB tester 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 UUT light
• Jumper settings - Test Tx/Rx isolation
  • Move left jumper to left position
  • Type data nothing should come back
  • Verify RX LED on the UUT 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
