100BaseFX Ethernet Port Connection

Remember to connect the Tx (transmit) port of device I to the Rx (receive) port

of device II, and the Rx (receive) port of device I to the Tx (transmit) port of

device II. If you make your own cable, we suggest labeling the two sides of the

same line with the same letter (A-to-A and B-to-B, as shown below, or

A1-to-A2 and B1-to-B2).

Turbo Ring DIP Switch Settings

EDS-505A/508A series are plug-and-play managed redundant Ethernet

switches. The proprietary Turbo Ring protocol was developed by Moxa to

provide better network reliability and faster recovery time. Moxa Turbo Ring’s

recovery time is less than 300 ms (Turbo Ring) or 20 ms (Turbo Ring

V2) —compared to a 3- to 5-minute recovery time for commercial

switches—decreasing the possible loss caused by network failures in an

industrial setting.

There are 4 Hardware DIP Switches for Turbo Ring on the top panel of

EDS-505A/508A that can help setup the Turbo Ring easily within seconds. If

you do not want to use a hardware DIP switch to setup the Turbo Ring, you can

use a web browser, telnet, or console to disable this function.

NOTE

Please refer to the Turbo Ring DIP Switch section and Using

Communication Redundancy section in User’s Manual for more

detail information about the settings and usage of Turbo Ring and

Turbo Ring V2.
