Figure 59 - 2.5 GHz Variant - Installation Wizard Wireless Configuration
Target MAC Address: It is the MAC Address of the peer unit that will be at the other end of
the wireless link. This is used by the system to ensure the unit establishes a wireless link to
the correct peer.
The MAC Address can be found embedded within the serial number of the unit. The last six
characters of the serial number are the last three bytes of the unit's MAC address.
(Note: A PTP 600 Series system is shipped as a pair of units with pre-loaded correct MAC
addresses. MAC addresses will only need to be entered if an existing unit has to be replaced
in the field or the units configuration has been erased).
Master Slave Mode: At this point it is necessary to decide which end will designate a Master.
The Master unit is the controlling unit with respect to the point-to-point link and its
maintenance. The master transmits until the link is made, while the Slave listens for its peer
and only transmits when the peer has been identified.
