SC-206X Series User Manual
Chapter 5
Installation and Operation
This chapter describes the hardware installation, signal connections, and operation of the SC-206X
Series boards.
Hardware Installation
The following are general instructions for installing your SC-206X Series board in your computer data
acquisition system. Consult your computer user manual or technical reference manual for specific
instructions and warnings. Notice that the installation instructions are the same for each SC-206X
Series board.
1.
Turn the host computer off before making any connections.
2. Install the SC-205X Series cable adapter board that is compatible with the host data acquisition
board you are using. Consult the SC-205X Series User Manual for instructions on the installation
of your SC-2050, SC-2051, SC-2052, SC-2053, or SC-2054 board.
3. It is advisable to use a 19 in. mounting rack or some other protective enclosure if you are using
the SC-206X Series board with high voltage. If you are not using high voltage, skip to Step 4.
Warning:
The SC-206X Series boards are for use where high-voltage isolation is necessary or
desired. To ensure operator safety, these boards must be mounted in a suitable enclosure
if they are connected to circuits that may have high voltages (greater than 42 V peak).
The rack-mount kit alone with the acrylic plastic cover does not provide adequate
operator protection unless additional coverage is provided on the top and bottom.
Remember to turn the power off when making any connections to any of these boards,
unless the top and bottom are also covered to prevent unintentional contact with high
voltage wiring.
a. Your SC-206X Series board mounts on one-third of a 19-in. rack chassis. You can mount
two SC-206X Series boards alongside any SC-205X Series cable adapter board except the
SC-2054 board, which occupies half of the rack chassis. You can mount your SC-206X
Series board on the left side, in the center, or on the right side of the 19-in. rack mount as
shown in Figure 5-1.
