Power On Configuration(JP3)
Default configuration after power on, and hardware reset is to set all the isolated output channels to open status (the current of the load can’t be sink) so that the external devices will not be damaged when the system starts or resets. When the system is hot reset, then the status of isolated digital output channels are selected by jumper
JP1. Table 3.2 shows the configuration of jumper JP3.

3.2.3
Channel-Freeze Function (JP2)
The MIC-3756 provides the channel-freeze function for isolated digital output channels. When Channel-Freeze function is enabled, all ports on the card will be locked so that the data transmitted (from the host PC) to the card won’t be transferred to the
DO ports. Once the Channel-Freeze function is enabled, each port status is immediately frozen into its last valid value before the Channel-Freeze. Since the value transmitted (from the host PC) to the card is also stored in the buffers on PC, users can call the relative function to read back the DO channel value, this function will determine that:
If Channel-Freeze function is disabled, it will return the DO value on the port
If Channel-Freeze function is enabled, it will return the value from the buffers on host PC
Refer to Table 3.3 for setting dry/wet contact of Channel-Freeze function.

Field Wiring Considerations
When you use MIC-3756 cards to acquire data from outside, noises in the environment might significantly affect the accuracy of your measurements if due cautions are not taken. The following measures will be helpful to reduce possible interference running signal wires between signal sources and the MIC-3756 card.
The signal cables must be kept away from strong electromagnetic sources such as power lines, large electric motors, circuit breakers or welding machines, since they may cause strong electromagnetic interference. Keep the analog signal cables away from any video monitor, since it can significantly affect a data acquisition system.
If the cable travels through an area with significant electromagnetic interference, you should adopt individually shielded, twisted-pair wires as the analog input cable. This type of cable has its signal wires twisted together and shielded with a metal mesh. The metal mesh should only be connected to one point at the signal source ground.
Avoid running the signal cables through any conduit that might have power lines in it.
If you have to place your signal cable parallel to a power line that has a high voltage or high current running through it, try to keep a safe distance between them. Alternatively, you can place the signal cable at a right angle to the power line to minimize the undesirable effect.
The signals transmitted on the cable will be directly affected by the quality of the cable. In order to ensure better signal quality, we recommend that you use the
PCL-10178-1E shielded cable.
