T/R Source or Sink
The “
TRMODE
x
” command is used to configure the mode of the T/R Source or Sink I/O line, where “
x
”
is
either 0 or 1.
The T/R Source or Sink settings are defined as:
•
0 = Source Mode. In Source Mode, the T/R Source or Sink line functions as an output. While in
Source Mode, an auto-sense circuit controls the T/R switching. When the Xtender is in transmit
mode, a logic
high
signal will be output on this line. Conversely, when the Xtender is in receive
mode, a logic
low
signal will be output on this line.
•
1 = Sink Mode. In Sink Mode, the T/R Source or Sink line functions as an input, and the T/R
switching is controlled by applying a logic
high
or logic
low
to this line. Applying a logic
high
signal to this line enables transmit mode, while applying a logic
low
enables receive mode.
•
Note: Factory default setting is 0 (Source Mode)
The “TRVOLT
x
” command is used to configure the
input and output logic levels
, where “
x
” is either 0 or
1. The T/R Logic Level settings are defined as:
•
0 = 3.3 VDC Logic
•
1 = 5 VDC Logic
•
Note: Factory default setting is 0 (3.3 VDC Logic).
