Communications Protocol Maximum sink current ≤ 4mA and the pull up resistor should be tied to 3.3Vdc. Open collector (HI) on this signal indicates The I²C protocol is described in detail by the I2C and PMBus that no Interrupt has been triggered. Serial Communications Protocol for the CAR Family of Power Supplies application note.( Document # 97FS2855) This signal is paralleled among the power supplies. Serial Bus Communications The I²C interface facilitates the monitoring and control of various operating parameters within the unit and transmits these on demand over an industry standard I²C Serial bus. All signals are referenced to ‘Signal Return’. Device addressing: The microcontroller (MCU) and the EEPROM have the following addresses: Device Address Address Bit Assignments (Most to Least Significant) MCU 0xBx 1 0 1 1 A2 A1 A0 R/W EEPROM 0xAx 1 0 1 0 A2 A1 A0 R/W Address lines (A1, A0): These signal pins allow up to four (4) modules to be addressed on a single I²C bus. The pins are configured automatically in the shelf. Rectifier addressing increments from left to right as viewed from the front. Address line (A2): This bit sets the address of the shelf. The bit setting depends on the rear accessible dip switch and pin 51 of the signal connector. In order to set the address HI (‘1’), the dip switch needs to be set to Mark 1 and the signal pin needs to be left open. Setting the dip switch to Mark 0 or grounding pin 51 will configure the shelf to address bit 0 (LO). Serial Clock (SCL): The clock pulses on this line are generated by the host that initiates communications across the I²C 2 Serial bus. This signal is pulled up internally to 3.3V [ 5V ] by a 10kΩ resistor. The end user should add additional pull up resistance as necessary to ensure that rise and fall time timing and the maximum sink current is in compliance to the I²C specifications. This signal is paralleled among the power supplies. Serial Data (SDA): This line is a bi-directional data line. . This signal is pulled up internally to 3.3V [ 5V ] by a 10kΩ resistor. The end user should add additional pull up resistance as necessary to ensure that rise and fall time timing and the maximum sink current is in compliance to the I²C specifications. This signal is paralleled among the power supplies. EEPROM The microcontroller has 96 bytes of EEPROM memory available for the system host. 2 Module configured with 5V standby output October 29, 2012 ©2012 General Electric Company.

The lug terminations can exit the shelf either above or below the shelf, or to the rear when right angle lugs are utilized. An insulation cover is provided over the lug terminations and it can be rotated to accommodate the cables exiting either upward or downward. The maximum output current capacity of the lug/wire combination should be sized to carry 300 amperes per set when two lugs are utilized. October 29, 2012 ©2012 General Electric Company.
