Break Out Boxes

Dis-allowed Connections

Do NOT connect these pins on E1432/3A end of cabling. These signals and supplies are provided for HP specified break out boxes and are unspecified for other usage.

Do not use:
15	I2C_EN
17	I2C_SDA
21	I2C_SCL
16	RFI GND/I2C Shield
18	RFI GND/I2C Shield
22	RFI GND/I2C Shield
19	BOB_EN
7	CAL_LOW
20	CAL_HIGH

23-24 V Power24+/-24 V GND Return25+24 V PowerIn general:

+/- DIFF n lines are the differential inputs for each channel. Shielded twisted-pair is recommended.

RFI GND/Drain Shield n are the grounds for the shield on the twisted-pair for each input channel. Connect at the HP E1432A/33A end of the cable only.

RFI GND/Cable Shield are the grounds for a shield around the entire cable, and the ground points for making individual channels single-ended.

I2C_xxx supply control signals to the active break out boxes. We do not provide support for other usage. These are not used with the HP E3240/1A Voltage and Voltage/ICP break out boxes.

RFI GND/I2C Shield protects the analog input lines.

BOB_EN is another break out box control signal. We do not provide support for its usage for anything but certain HP-specified break out boxes.

CAL_HIGH/LOW are signal lines to send calibration signals to the HP-specified break out boxes. The signals available on these lines are not specified and their usage is discouraged.

+/- 24V Power and GND supply power to the signal conditioning circuitry in the active break out boxes, and ICP in the active ICP break out box. The power available on these lines is not specified and their usage is discouraged.
