18 Access Point Controller Card (APCC)
Installation Guide
Sensys Networks, Inc.
Factory Default Card ID
Card IDs are implemented on Sensys Networks contact closure cards via two dip
switches found on the side of the card. In this guide, the switches – named SW1
and SW2 respectively – are referred as
circuit-board
dip switches to differentiate
them from other dip switches on the front-panel of contact closure cards.
A default Card ID of “03-15” is assigned at the factory and is shown in the
following figure.
N
OTE
:
On the card, switches SW1 and SW2 are not as close to one another as shown in the figure.
Figure 5.1. Default card ID (all dips down)
Before proceeding, ensure that switches SW1 and SW2 are set as in Figure 5.1 and,
additionally, that all front-panel switches are in the right-hand position.
Querying the Backplane for an Assigned Address
The APCC support an operating mode (called
X mode
) that queries the traffic
controller backplane for an address. Because it can be difficult to determine from
visual inspection if the backplane dictates card addresses, the standard practice is
to use
X mode
to see if this is the case.
X mode
uses the four front-panel channel LEDs to visually indicate the backplane
address assigned by the controller (if any). (Refer to
for a figure that depicts how the channel LEDs are used.)
Follow these steps to use X mode to query the controller for a card address:
1. Verify that the APCC is set to its default Card ID and that all front-panel
switches are in the right-hand position.
2. Reset the APCC by pressing the master reset button (located on front-panel
next to channel LEDs) or removing the unit from the cabinet and re-inserting
it.
3. Observe the front-panel channel LEDs. Match the pattern of lighted LEDs
with the figure in
Appendix A: X Mode LED Displays for Slot Numbers
The address value that matches the LED display pattern (from
Appendix A
) is the
slot number
component of the Card ID.
