All connections are made via industry standard CCITT V.35 (MR-34) female connectors
located on the rear of the unit. The Following interface leads are implemented, Chassis (A),
TD (P,S), RD (R,T), RTS (C), CTS (D), DSR (E), Sig Gnd(B), DCD (F), TT (Y,AA), RT (V,X),
DTR (H), ETT (U,W).

Front Panel LEDs
Front panel LEDs are provided to indicate power is applied, RD and TD activity from the
Master Port, Sub-Channel activity of each individual Port, Anti-Stream condition of each Sub-
Channel and an indication of clock Fallback condition.
Channel Enable / Disable Switches
Front panel switches allow operator intervention to remove an individual Sub-Channel from
accessing the Master Port. Positive latching type switches are provided for each Sub-
Channel port for isolating or removing a streaming terminal. The Sub-Channel is activated by
pushing the switch until it is in the “

indicate BLACK in color. Disabling a Sub-Channel with the front panel does not prevent the
Sub-Channel from receiving data from the Master Port only from sending data to the Master
Port.

rear of the unit. If chassis ground and signal ground need to be tied together this can also be
accomplished by switch selection. The unit is Rackmountable for 19" cabinets or optional 23"
cabinets, by using the provided Rackmount Kit. Safety approvals granted are UL and CSA as
well as emission approval for FCC Class A.
