CHAPTER 4
Port Address and Offset Configuration
The IC-124 when used in a SG-7000 series interface cabinet has self-addressing capabilities, enabling automatic
configuration (see Chapter 3). When received from Med Associates IC-124 address and offset DIP-switches
should all be in the OFF position. If the switches are set to OFF, the IC-124 is assigned the appropriate address
and offset within the system when the SG-7000 series cabinet is turned on. As it does so, the cards count off their
assigned number in the light display on the front of the card. These values align themselves based on card
positioning within the cabinet. If a card is manually addressed, it will count off its position number in red lights
instead of green.
FIGURE 4.1 IC-124 DIP-SWITCHES IN THE "OFF" POSITION ALLOW SELF-ADDRESSING
Manually addressing an IC-124 card is designed to be a rare application. If the user finds their application
requires it, a call to Med Associates support (see p. 28) may lead to more efficient solutions. It can be done. In
Example 4.1 below, to manually set an IC-124 in slot 3 with the DIP-switches set to card two, set the address to
794 and offset to 4 (A2 switch ON).
Especially if used together it is important to know how to avoid or target duplicating addresses and mirroring
cards. In Table 4.2 and Table 4.3, the DIP-switches are referenced for OmniCtrl cards intentionally mirroring
addresses. When a manually addressed IC-124 card starts up it counts off its position number, not its addressed
number, in red lights on the front of the card. One can confirm the correct address and offset in Med Test by
checking the card data (see Figure 2.5 Items B, C). SmartCtrl cards (DIG-716 or 716B) or SuperPort Cards (DIG-
713A or 726) cards will still need manual configuration. Please reference their user manuals for more detailed
information on those systems. For reference and comparison those DIP-switch settings are also present in Omni
Control and SuperPort I/O PORT and Offset Values Table 4.2 and Table 4.3.
