Is power supply needed for the IDE-SERIES Kit?
No external power supply will be needed for the IDERC kits. The unit will get its power from the PC serial COM port automatically. So less cables, less hazard around and lower power consumption. ( However in the case of using external sensors that derive high power from its source, external power is needed to cover up the power supplied by the PC com Port. If signs of insufficient power supply or unstable data reading is detected, we would suggest an external power supply). Local power adapter with output of 9VDC 300mA, center post +ve, outer Gnd, could also be used. We can also provide suitable power adapters (Please specify local power supply either 120VAC or 240VAC). No power supply will be needed for IDERC1 as it is only a single channel unit. Please determine the power dissipation of the external sensors used. External power is not needed if no reading error is detected (most likely due to unsufficient power supply by the PC serial com).
