OTHER TWO-PORT DEVICE (SEQuencer type)
Additional types of two-port RF boxes can be
added using Other template. When using Other
template, Router generates Interconnections and
Rules tabs as for the other two-port RF boxes but
control box must be added manually using the
Add Control button. Any combination of control
boxes can be used with a two port RF box. In
addition to the special local PA control type,
DATA type for PA control purpose, and FRQ type
for frequency dependent relay outputs, SEQ type
T/R switching may be defined using relay
outputs.
To add sequencer control for an RF box, uLINK
or local RELAY sequencer control box must be
added using Add Control button.
CONTROL BOX
Specifies which control box will be used for this RF box control. The control box must specify a relay unit with
exactly same number of relay outputs as used for sequencer outputs. Only control boxes with equal relay outputs
will be shown in drop down menu.
Sequencer outputs list
First line PTT source in the list window is just informative and shows T-R waveform in both IN and OUT
frequency ranges for better visibility.
Sequenced Outputs can be added or removed using the Insert and Remove buttons and reordered with the Up
and Down buttons. The Order reflects the physical position of the outputs within a control box unit. Outputs are
numbered upward from the lowest to the highest reference in the unit, Output 1 is the lowest output number in
the unit.
Frequency ranges
•
One or more frequency ranges can be defined for each output. The default frequency range can be
edited by a single click on selected range. To show frequency ranges, click on Show frequency ranges
button or expand list tree by clicking on the
IMPORTANT: Each output can be renamed by single click on Output line. We recommend naming each
output because the output relay can be changed with the UP and DOWN buttons. Without
names, it is easy to lose track of the purpose of each output.
NOTE: Frequency ranges for sequencer are always fixed to TX frequency.
Hold
•
Specifies sequencer output polarity if frequency is Out of range. Hold polarity can be set independently
for each SEQ output. Output can be active or inactive. Out of frequency range sequencer output does not
copy PTT source.
Invert (Inv.)
•
Defines sequencing polarity. Active state (while PTT lasts) can be open or closed contact. Rising edge
on waveform means that contact is closing.
Lead
•
Defines delay between rising edge of PTT source (start of the T-R source cycle) and start of sequencer
output in milliseconds.
