Cause and Remedy
• If the Firewall is installed in the computer, communications
with the Air Shot Version 2 may be blocked, which may
cause an irregularity; the projector cannot be detected or
connected, or the projector is disconnected in midway.
c Set the Firewall so that the following port numbers Air Shot
Version 2 uses will not be blocked. For how to set the
Firewall, see the manual of the Firewall software you use.
Port numbers that Air Shot Version 2 uses:
- 51217 (TCP/UDP)
- 53125 (TCP/UDP).
Note
If you release the block carelessly, the computer becomes unguarded and
may be suffered by a dangerous virus attack. Consult with the network
administrator and pay special attention to firewall setting. Allow the
communication for only the necessary ports.
