Operation
Interface Connections
All connections are made via industry standard DB-15 (V.11) female connectors located on
the rear of the unit. The following interface leads are implemented: T(2,9), R(4,11), C(3,10),
I(5,12), S(6,13), B(7,14), Gnd (8), Chassis(1).
Front Panel Indicators
The front panel LED indicators associated with each sub-channel identify the active port. A
green POWER ON LED indicates when AC voltage is applied. Two adjacent green LED
indicators illuminate in union with individual port activity and identify Transmit Data (T) and
Receive Data (R) activity. When in Fallback Mode the Fallback LED will illuminate.
Channel Enable / Disable Switches
Positive latching type switches are provided for each DTE port for isolating or removing a
streaming terminal. When activated the switch will indicate GREEN in color. To disable a
sub-channel push the switch inward, the switch will indicate BLACK in color. The port Enable /
Disable, front panel switches must be pushed in (GREEN) for a sub-channel to access the
main channel. Data will be sent from the master to the ports regardless of the Enable /
Disable switch setting, only data from the ports to the master is affected.
Power Supply
A linear power supply is located internally, an external 110/220VA switch is located on the rear
of the unit. If chassis ground and signal ground need to be tied together, this can be
accomplished by switch selection. The unit is Rackmountable for 19” cabinets or optional 23”
cabinets, by using the provided Rack Mount Kit. Safety approvals granted are UL, CSA and
TÜV, as well as emmision approval for FCC Class A and VFG-243.
