Use a DB‑9 cable to connect the load’s RS‑232 COM port to the computer’s COM port and ensure matching baud rate, parity, data bits and flow control.
Verify that the AC voltage setting (110 V or 220 V) matches the supplied mains voltage, otherwise the load may be damaged.
The load provides over‑voltage, over‑current, over‑power, and over‑temperature protection with thresholds such as ≈130 V, ≈33 A, ≈260 W, and ≈85 °C.
