8. Verify that the version numbers for the
HW Version x.x
and
VHDL Version x.x
are valid (i.e.
1.0, 2.1, etc.) If a question mark (?) or some other character appears, an error has occurred.

2.4 I2C Tx/Rx Session
For this exercise, a target slave device (included with the JI-300 kit) or I2C network with at least
one slave device will be needed. Device power (or network) can be supplied by either the I2C
target or JI-300 Adapter. The following steps are for use with the test M24C04 I2C target device.
1. Ensure that the I2C Host Adapter unit is connected and power is on. (Section 2.2 Hardware
Setup)
2. Ensure that the I2C Host Adapter application is running and the USB port is open. (Section 2.3
Communications Check)
3. Connect the I2C probe cable to the D-sub connector on the I2C Host Adapter front panel.
4. Locate the test M24C04 I2C (4Kbit Serial I2C EEPROM) target device supplied with the kit.
(See Figure 2)
5. Connect the four I2C bus probes (SDA, SCL, PWR, and GND) to the I2C target device. (See
Figure 2)
