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.

DATA TRANSCEIVER
1) ANTI-STREAMING SELECT SWITCH
The anti-streaming function is provided to protect the communications channel in the
event that a controller should go into a streaming or data-storming condition.
If the anti-streaming is to be used, it must be set to a setting that will exceed the longest
possible data transmission time that will exist on that channel.
most installations, the anti-streaming will not be utilized and the switch should be left in the
factory default “Off” position.
See Pg. 11, Fig.18.
2) DTE/DCE SELECT SWITCH
The purpose of this switch is to transpose the RS-232 data transmit and data receive signals.
Normally,this switch will be left in the factory default “DCE” position.
See Pg. 9, Fig.12 through Fig. 15.
3) LINKING PORT, J3
J3 is an RJ-11 connector utilized for electrically connecting two co-located FDX55 units.
For example,at some point on an east-to-west communications channel, it may be desired to
extend the channel in the north-to-south direction. A second FDX55 may be added in the same
cabinet as another existing FDX55, and the second unit would be utilized for extending the
channel in the north-to-south direction. A conventional straight-through interconnect cable
terminated at each end with RJ-11 connectors is required when connecting the two FDX55
units. It is desirable to keep the length of this cable as short as possible, so as to minimize
any possibility of stray electrical pick-up corrupting the quality of the data, which could
result in data errors.
See Pg. 8, Fig. 11 and Pg. 10, Fig. 17.
It should be noted that in
4) A/B SELECT SWITCH
The purpose of this switch is to transpose the data transmit and data receive signals when
connecting two co-located FDX55 units utilizing the J3 expansion port and a straight-through
data interconnect cable. One FDX55 will be set to “A” and the second FDX55 will be set to “B”.If a
cross over cable is used,then both FDX55s would be set to “A”. This interconnect cable should be
kept as short as possible to eliminate EMI/RFI noise injection. Refer to Figure 1 for
typical configuration. Factory default for this switch is “A”.
