supply. Note: If two or more 8 way relay boards (TS1041) are used, the link
should be removed and the relay boards should be powered from an external
supply.
Note: Devices connected to the RS-485 buses and powered by the Network
Access Controller must comply with Appendix B: Output fusing and user current
limits on page 34
Connecting to Aperio
The Aperio
®
protocol is a short distance wireless communication protocol
designed to link an access control system with an Aperio enabled mechanical
lock.
A single Aperio hub can be connected to each local bus on the NAC. For
connecting to either local bus, configure the address on the Aperio hub to 1.
Refer to the Aperio hub’s installation manual for information on configuring the
bus termination resistors.
LED indicators
LEDs on the printed circuit board indicate the state of the Network Access
Controller, the ChallengerPlus system LAN, the local LANs (BUS 1 and BUS 2),
and Ethernet activity.
Table 3 below shows the LEDs for each of the items above. The numbers in the
Item number column indicate the LED location on the Network Access Controller
as shown in Figure 2 on page 12.
Table 3: LED indications
Slow flashing indicates normal operation.
Rapid flashing if firmware update or Network Access Controller default
is in process.
Flashing indicates the Network Access Controller is replying to polling
from the ChallengerPlus panel on the system LAN.
Off indicates that the Network Access Controller is not correctly
addressed, the ChallengerPlus panel is not programmed to poll the
DGP address, or there is no ChallengerPlus panel connected.
