ADDENDUM
The Comnet FDX55 Series has recently undergone some enhancements.
The three enhancements are summarized here. Please verify which version
of the FDX55 you have by examining the front and rear panels for the following
changes. These changes are reflected in this Installation and Operation
manual and will allow you to correctly configure the device for proper operation.
1) The silk screened printing on the front of each FDX55 Series device had
previously shown a "JABBER RESET" button. The silk screened printing was changed
and now reads "ANTI-STREAMING RESET" for this button.
2) Linking port J3 originally used an RJ-45 receptacle.
This now has been changed to an RJ-11 receptacle.
3) The FDX55 was originally designed as a DCE device with a switch labeled "NA/DCE"
to allow for possible future use as a true "DCE/DTE" switch. The device has now changed to
allow for the selection of DCE or DTE via the front panel switch labeled DTE/DCE.
The setting of this switch is detailed later in this manual.
