The longer 20ms frame size reduces the overhead and increase the throughput, but the
drawback is a higher overall latency due to longer cycles. It may not be suitable for latency-
sensitive, real-time applications.
CAUTION – Extreme ratios such as 9:1 and 1:9 should be avoided for most
applications, particularly with the 40MHz channel size operation.
System Mode
A PTP unit can be either a Master unit or Slave unit. One side must be chosen as Master and
the other as Slave. The functions are very similar between the two units, but the Master unit has
a few more control parameters, for which the Slave unit will follow the Base configuration.
Management Access
Via VLAN Enable/Disable. If access to the Web GUI will be from a PC within a VLAN, then
this feature should be Enabled. If access is from a PC outside of a VLAN, then this feature
should be Disabled.
VLAN ID: The ID should be set to match the VLAN ID used on your management PC. This
setting does not affect any other VLANs running on your network or the ability to pass VLAN
traffic.
WARNING - Enabling Management Access via VLAN will lock-out HTTP and
Telnet access if attempting to connect from a PC without the proper VLAN
configuration. Access to units with an unknown VLAN configuration can be
recovered through the use of Solectek’s Recovery utility software on radios running
recent revisions of software. Check with Solectek Support for details.
Ethernet Configuration – This section allows users to configure the Ethernet port manually,
particularly for interfacing with older hardware. Solectek strongly recommends using auto-
negotiation default mode in most cases.
NOTE - Autonegotiation is REQUIRED for 1000BASE-T operation, per the IEEE
802.3-2002 standard: "a) To negotiate that the PHY is capable of supporting
1000BASE-T half duplex or full duplex transmission. b) To determine the
MASTER-SLAVE relationship between the PHYs at each end of the link."
