Ollie is an isolated, multifunction interface module and USB-to-isolated-UARTx2/CAN/USB/RS485/RS232 converter. This versatile device combines our most commonly used interface modules into one safe, reliable, compact, and affordable package.

Documentation

Features and Specifications:

Isolated UART:

• Two isolated UART ports (UARTA and UARTB)
• Data Rate up to 12 Mbps
• 1.8/3.3/5 V voltage levels (set by slide switch)

Isolated CAN:

• Based on CANable/CANtact open hardware
• Supports PCAN-USB emulator firmware
• By default flashed with dual firmware CANtact and Candlelight, firmware is set by the DIP switch
• Termination Resistor switch
• ESD protection

Isolated Power Supply:

• 1.8/3.3/5 V output voltage(set by slide switch). Output voltage can set only before USB is plugged in, to prevent accidental level change (hackable in firmware)
• Current-limited with auto-restart
• Reverse voltage protection up to 10 V
• Reverse current protection
• Reverse polarity protection

Isolated downstream USB:

• USB Type-A connector
• Supports 1.5 Mbps (Low Speed) or 12 Mbps (Full Speed) USB devices
• Current limited with auto-restart
• Reverse current protection
• ESD protection

Isolated RS485:

• Bias and Termination resistors switches
• Error-free transmission up to 500 kbps
• ESD protection

Isolated RS232:

• Typical data rate of 235 kbps
• RS232 TX/RX pins ±12V. RS232 RX Absolute Max ±25V.

• ESD protection

• optional: CAN/RS232/RS485 DB9 pluggable connector

Configurable DB9 Adapter Ollie can be used with a configurable DB9 adapter which can be plugged in instead of the screw terminal. The function can be selected by moving all three DIP switches to the desired configuration. Also CAN OBD-II or CiA 303-1 function can be selected using the jumpers.
