b. Windows XP (x86), Vista (x86/x64), 7 (x86/x64), 8, 10. • Windows XP+ • Linux 2.6+ • Mac OSX 10.5+ 2. Interconnects The i2cStick 2 includes two interconnections: USB Connector The USB Type A connector provides connection from the I2C adapter to a USB port on the host computer or self-powered USB hub. The i2cStick 2 operates as a high-power (>100 mA) bus-powered USB device, with up to 100 mA of (user optional) switch-selectable 3.3v or 5v for I2C Bus target system power. Virtual Communications Port (VCP) The i2cStick 2 uses a Virtual Communications Port (VCP) interface to communicate with a host computer via USB. A virtual serial port is created on the host computer when the driver is installed. Drivers are available for several operating systems, and can be installed separately, or while installing the iPort Utility Pack.

address: www.mcc-us.com/i2cStick-2 After the driver software is installed, plug the i2cStick 2 into a host computer USB port, or self-powered USB hub. Upon detecting the device, the operating system will automatically load the driver and create a new “virtual” serial port for communicating with the i2cStick 2. Once installed, application programs running on the host computer can communicate with the i2cStick 2 via the operating system serial port Application Program Interface (API). The i2cStick 2 uses the following VCP serial port signals: • TX - Transmit Data from the Host Computer to the i2cStick 2. • RX - Receive Data from the i2cStick 2 to the Host Computer. • RTS - Request to Send from the Host Computer to i2cStick 2. • CTS - Clear to Send from the i2cStick 2 to the Host Computer. Serial communications flow-control options include X-ON/X-OFF (default) or RTS/CTS. The flow-control method used by a host computer application should match the flow-control method selected for use by the i2cStick 2 host adapter. I2C Mini Interface Connector The i2cStick 2 includes a five wire (1x5) 2.54 mm (.100"), positive locking, shrouded header connector (see Appendix A) for interfacing to an external I2C Bus. Interface lines provided include: • I2C Clock (SCL) • I2C Data (SDA) • Shield (optional) • Ground • +V (optional) Minimum wiring for I2C Bus communications include I2C Bus Clock, Data, and Ground. Use of the +V and Shield wires in the I2C Interface connector are user optional. NOTE: See the Hardware Configuration section below for additional information

I2C Bus Mini Interface Receptacle Mini Interface Receptacle Pinout I2C Bus Mini-Clip-Lead cables are available to connect the i2cStick 2 adapter to a target system. Each clip-lead is identified (White=C=SCL, Red=V=+V, Green=D=SDA, Black=G=Ground). I2C Bus Mini-Interface cables with two Mini Interface plugs are also available to connect the I2C adapter to an external I2C Bus. 3. Hardware Configuration Circuit Sense™ The i2cStick 2 includes MCC’s Circuit Sense technology. Circuit Sense allows the I2C interface +V wire to operate in two modes, Power Source Mode and Voltage Sense Mode. Mode selection is controlled by the MODE slide switch on the side of the unit enclosure. • Power Source Mode - The +V wire can supply power (3.3v or 5v @ 100 mA) Vcc to an external I2C Bus system. Voltage selection is controlled by the SOURCE slide switch on the side of the unit enclosure. In Power Source Mode, the voltage of the i2cStick 2 SCL and SDA internal pull-ups, if enabled, and Voltage Sense circuit (0.3Vcc LowMAX, 0.7Vcc HighMIN) is selected by the SOURCE switch. (Use of the +V wire in Power Source Mode is user optional). Power Source Mode is similar to the standard mode of operation on earlier versions of MCC I2C Bus host adapters.

pull-up supply reference voltage (0.5v to 5v) Vcc. In this mode, the i2cStick 2 SCL and SDA voltage sense circuits automatically adjust to match (0.3Vcc LowMAX, 0.7Vcc HighMIN) the external reference voltage. In Voltage Sense Mode, the voltage of the i2cStick 2 SCL and SDA internal pull-ups, if enabled, is supplied by the external voltage (Vcc) applied to the +V wire. (Use of the +V wire in Voltage Sense Mode is required). I2C Bus Pull-up Resistors I2C Bus systems are based on open-collector technology requiring pull-up devices on each signal wire (SCL and SDA). These pull-up devices usually take the form of pull-up resistors connected to bus power. The i2cStick 2 adapter includes a PULL-UPS slide switch used to enable or disable internal 1.8K ohm pull-up resistors attached to the SCL and SDA lines. Every I2C Bus system must have at least one pull-up on the signal lines. In some cases, the pull-ups may be present in the external I2C Bus circuit. Use this switch to configure the pull-up resistors for your system. See the Power Source Mode and Voltage Sense Mode sections for applied pull-up voltage. Connecting to an SMBus Target System If you are connecting the I2C adapter to a SMBus target system, you should follow these steps BEFORE applying power: • Shut off the I2C adapter’s internal pull-ups (See Pull-up Resistor section). • Use external SMBus rated (appoximately15k ohms) pull-up resistors. These pull-ups may already be present in the target system. • Visit our I2C versus SMBus FAQ page (www.mcc-us.com/I2CSMBusFAQ.htm). • See the SMBus Specification for additional details. Special Note for SMBus Users: MCC’s I2C adapters are designed to be I2C Bus compatible, not SMBus compatible. Some features of the SMBus protocol not supported include time-outs, device reset, and Packet Error Check byte processing. The non-supported SMBus features may, or may not, permit the use of the I2C

Specification for details. 4. ESD (Electrostatic Discharge) Precautions Electrostatic discharge is defined as the transfer of charge between bodies at different electrical potentials. Electrostatic discharge can change the electrical characteristics of a semiconductor device, degrading or destroying it. Electrostatic discharge also may upset the normal operation of an electronic system, causing equipment malfunction or failure. When connecting the I2C adapter to a host computer and a target system, extreme care must be taken to avoid electrostatic discharge. Failure to follow ESD protection procedures when using the I2C adapter could damage the host computer, I2C adapter, or the target system, and void product warranty coverage. Host Computer Grounding Case 1 - Desktop and Single-board Computers. The chassis on a desktop or single-board host computer must be connected to earth ground to comply with safety regulations. If the computer chassis is NOT connected to earth ground for some reason (i.e., use of a two-prong power mains plug), the host computer power supply ground will float to some unknown voltage potential. Case 2 - Laptop Computers. Laptop computers present special ESD problems. Most laptop computers use an external double-insulated mains power supply which is NOT connected to the mains earth ground. This means that the laptop chassis is floating at some unknown voltage potential. In either case, upon connection to the I2C adapter and the target system, the host computer will discharge energy through its serial port to the I2C adapter, and on to the target system. This discharge could damage the host computer, I2C adapter, and the target system. Grounding Solutions To avoid damage to the host computer, I2C adapter, or target system, follow these instructions: • Wear an earth grounded wrist strap, or discharge any static charge build-up,

• Ensure that both the host computer and target system are connected to a common earth ground point. • Make sure that all interconnections are made BEFORE applying power to the host computer, I2C adapter, and target system. • If you are using a laptop computer or host computer that is NOT connected to mains earth ground, make a hard-wired connection from the host computer (i.e., port connector shell) and the target system ground connector to a common earth ground point. • Avoid plugging and unplugging system components while the host computer or target system is powered. • Ensure that any devices connected to the target system are properly grounded to the common earth ground point. • If unsure how to properly ground system components, seek electrical expert help. WARNING: Any damage caused by Electrostatic Discharge (ESD) through inadequate earth grounding is NOT covered under the warranty of this product. 5. Driver Software Set-Up The i2cStick 2 uses a Virtual Communications Port (VCP) interface to communicate with a host computer via USB. A virtual serial port is created on the host computer when the driver is installed, and the i2cStick 2 is plugged in. Drivers are available for several operating systems, and can be installed separately, or while installing the iPort Utility Pack. The stand-alone driver and iPort Utility Pack are available at the following link: www.mcc-us.com/i2cStick-2 This section provides information on how to install, update, and uninstall the i2cStick 2 software driver on a Windows-based host computer.
