Earthing Terminal; Connecting Two Acw2-Xn Units Via Rs-485 - HID ACW2-XN Installation Manual

Web-Based Access Control Solution
ACW2-XN
DIP-switch Position
Note:
• FACTORY DEFAULT IS AN ABSOLUTE LAST RESORT
Defaulting the Controller Module will erase all HID Access Manager data, including any static IP
address that was set up – so this address should be noted somewhere safe for future use.
• The most likely reason for choosing to default a Control Module would be when the HID Access
Manager IP address is accidentally set outside of the mask, and HID Access Manager becomes
inaccessible.
• As long as the IP subnet of the Controller Module is the same as the PC/Laptop, the Device
Discovery Tool may be used to discover the address and allow you to login and set up an
appropriate IP address. The Device Discovery Tool is available for download from the "More
Documentation" link included on page 2.

Earthing Terminal

The Controller and Wiegand Modules are sensitive to Electrostatic Discharges (ESD). Observe
precautions while handling the circuit board assemblies by using proper grounding straps and handling
precautions at all times.
To furher protect against the harmful effects of EMC and transients, a functional earth connection point is
provided as a screw terminal (see silkscreen marking: ETH).
SYSTEM BACKUP
Always back up the system data using the Access Manager Utility Tool. This could save you having to
set up the system from scratch again in the event of a system default, as described above. The Access
Manager Utility Tool is available for download from the "More Documentation" link included on page 2.

Connecting two ACW2-XN units via RS-485

Link the two Controller Modules by connecting their RS-485 Device terminals. Remember to set the DIP
Switches on the second Controller Module (in the remote ACW2-XN) to SLAVE (0000) – and remember
to cycle the power to the module in question if you have changed the DIP Switch Settings while it is
already in the powered up state.
Note:
•
The Slave ACW2-XN is NOT connected to the Network
• The total door count (Slave + Master) may not exceed 16 doors
