3.2.2 Power On Configuration(JP1)
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 JP1.

3.2.3 Channel-Freeze Function (JP2)
The PCI-1756 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.

3.3.2 Isolated Digital Input
Each of isolated digital input channels accepts bi-directional 10 ~ 50 VDC voltage
inputs. Meaning that you can apply positive or negative voltage to an isolated input
pin (VIN). Every 16 input channels share one common pin. Figure 3.3 shows how to
connect an external input source to one of the card’s isolated input channels.

PCI-1756 User Manual

Each of isolated output channels comes equipped with a MOSFET, polyswitch (for
current protection) and flywheel diode for using with inductive loads which can be
activated by connecting PCOM to VDC. If an external voltage (5 ~ 40 VDC) is applied
to an isolated output channel, the current will flow from the external voltage source to
the card. Please note that the current through each IDO channel should not exceed
200 mA.

3.3.4 Channel-Freeze Function
The PCI-1756 provides a digital input channel (CH_FRZ_IN) to enable the channelfreeze function. The channel-freeze function acts when the pin CH_FRZ_IN is activated. Moreover, you can setup the input mode of channel-freeze function input
channel CH_FRZ_IN as dry contact input mode or wet contact input mode selected
by on-board jumper JP2. The wiring in wet contact and dry contact input mode are
shown in Figures 3.5 and 3.6.

3.4 Field Wiring Considerations
When you use PCI-1756 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 PCI-1756 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-10250 or PCL-101100M shielded cable.
