Table 2-1 details header information for three sections of the board. Optional power connections to an external DAC or MCU are provided for each XTR102 and XTR120 section. Each section is partitioned as a separate board and signals are isolated between the different sections. Power and GND must not be mixed between the different board sections.
| Section | Header | Function |
|---|---|---|
| XTR100 | J3 | Loop power: LOOP+, LOOP- |
| J4 | Input signal: VIN, GND | |
| XTR102 | J6 | Input signal: VIN, GND HART interface: HART_Rx, HART_Tx Output power (optional): VCC, VREF |
| J8 | Loop power: LOOP+, LOOP- | |
| XTR120 | J13 | Loop power: LOOP+, LOOP- |
| J14 | Input signal: PWM_IN, GND HART interface: HART_Rx, HART_Tx Output power (optional): VCC |
