18 | OMNI POWER AND CONTROL INTERFACE SYSTEMS
Upon opening the HCU, the screen presents a view of the interface cabinet (see Figure 3.1 Hardware
Configuration Utility). An important feature of this utility that is different from other versions of Med-PC
configuration utilities users may be familiar with is the "Auto Map" Feature. Systems set up with all OmniCtrl
cards can either be set by the "AutoMap SmartCtrl and OmniCtrl Cards" (for one test chamber per interface
card) or "Auto Map 2 Boxes Per OmniCtrl Card" (for grouping two environments per interface card). Most other
configurations will be set by selecting the "Auto Map All Cards" option. When hardware configurations are
changed this step needs to be applied again (see I/O Configuration below).
Important other links to note are the "Adjust Rack Size" to manually set the rack size of 8 or 16 Interface Card
slots and the "Add Card" to open the "Add Card" window to manually configure the card and the I/O port and
offset information. Click "OK" to close these setting windows and add the configured changes. To insert multiple
cards of the same type with the same configuration together, click the "Add Multiple Cards of the Same Model"
link. Notice that setup windows have dialogue intended to help understand the options that are present when
setting up different configurations.
Automatic port and offset settings are assigned sequentially based on the card's physical location in the rack. If
the desired port and offset settings differ from this convention, click the "Edit Address" link at the bottom of a
card slot to adjust the port and offset values to match the physical switch/jumper settings on the card (see Chapter
4 Table 4.1 and Table 4.2).
I/O Configuration
FIGURE 3.2 CONFIGURE I/O CHANNELS
Automatic I/O settings default to input operation. To change the setting for outputs from the "Hardware
Configuration" window, toggle the check boxes for every card you wish to set the outputs on and click the "Edit
Address" link. This will raise the "Edit Address of IC-124 OmniCtrl" window. If you wish to Copy I/O
configurations from another previously set up card, you may choose the "Copy I/O Channels" button. Otherwise
choose the "Define I/O Channels" button. This will raise the "Configure I/O Channels" window.
