2.1.2 MODE DIP Switch
The Industrial Ethernet Extender provides 4 selective transmission
modes. By switching the transmission modes, you can obtain a best
transmission mode to suit with phone line quality or distance of
connectivity. The following is the summary table of transmission setting,
bandwidth and distance extensibility tested for AWG 24 (0.5mm)
twisted-pair without noise and cross talk.

Master / Salve
t
Master (Central Office) – the Master device mode, usually the
Master device will be located at the data center of ISP or enter-
prise to link to the backbone.
t
Slave (Customer Premises Equipment) – the Slave device mode,
usually the Slave device will be located at branch office, home or
remote side as the long reach data receiver. The Slave also can be
connected to the PC, IP Camera or Wireless Access Point and etc
network devices.
Note
When the Industrial Ethernet Extender operate at Slave
mode, the DIP switch 2,3,4 is no function.
Fast and Interleave mode
t
Fast mode guarantees a minimum end to end latency less than 1
ms.
t
Interleaved mode provides impulse noises protection with a dura-
tion less than 250 us. Interleaved mode has a maximum end to
end latency of 10m sec.
