PCIE-1752 User Manual 2
Board ID Setting
The PCIE-1752 has a built-in DIP switch that helps define each card’s ID
when multiple cards have been installed on the same PC chassis. The
board ID setting function is very useful when users build their system
with multiple PCIE-1752 cards. With correct Board ID settings, you can
easily identify and access each card during hardware configuration and
software programming.
Channel-Freeze Function
The PCIE-1752 provides Channel-Freeze function, which can be enabled
either in dry contact or wet contact mode (selectable by the on-board
jumper). When the Channel-Freeze function is enabled, the last status of
each digital output channel will be safely kept for emergency use. Moreover, you can enable this function through software as it is useful in software simulation and testing program.
Reset Protection
When the system has undergone a hot reset (i.e. without turning off the
system power), the PCIE-1752 can either retain outputs values of each
channel, or return to its default configuration as open status, depending
on its on-board jumper setting. This function protects the system from
wrong operations during unexpected system resets.

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.
Table 3.2: Power on configuration after hot reset (JP1)
JP1 Power on configuration after hot reset
Keep last status after hot reset
Default configuration (Default setting)
3.2.3 Channel-Freeze Function (JP2)
The PCIE-1752 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.

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 PCIE-1752 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.
