031 – Guard Out #1 This indicates that the receiver for channel #1 is receiving a valid guard
signal (this is the only receiver in an Rx or Tx/Rx chassis).
032 – Guard Out #2 This indicates that the receiver for channel #2 is receiving a valid guard
signal (this is the second receiver in an Rx/Rx chassis).
033 – Trip Out #1 This indicates that the receiver for channel #1 is receiving a valid trip
signal (this is the only receiver in an Rx or Tx/Rx chassis).
034 – Trip Out #2 This indicates that the receiver for channel #2 is receiving a valid trip
signal (this is the second receiver in an Rx/Rx chassis).
035 – Trip Key #1 This indicates that the first key input for transmitter channel #1 is active.
036 – Trip Key #2 This indicates that the second key input for transmitter channel #1 is
active.
037 – Trip Key #3 This indicates that the first key input for transmitter channel #2 is active.
038 – Trip Key #4 This indicates that the second key input for transmitter channel #2 is
active.
044 – IRIG-B Status This indicates the IRIG-B signal lock status. When locked, the IRIG-B
signal is coming into the chassis or is present.
Parameters 053 - 056 are normally pre-set at the factory, or can be set in the field by the user. These
parameters must be set, before meaningful Reflected Power readings can be read in the Values Display.
For example, in a TxTx chassis with X-Hybrids in the Channel 1 and Channel 2 transmit paths,
parameters 054 and 056 must be set to Y (yes). Then set the Channel 1 and Channel 2 frequencies in
parameters 053 and 055 as applicable. The settings of these parameters are essential in calculating the
Reflected Power readings in the Values Display, as shown in paragraph 16.5.
053 - Freq Ch1 (Hz) This parameter is set to the Channel 1 transmit frequency. This parameter
is only used if parameter 054 is set to Y (yes), and is only applicable in a
TxRx, TxTx, or Tx only chassis that has an X-hybrid installed in the Tx
Channel 1 output path.
054 - X Hybrid Ch1 This parameter is set to:
Y (yes) if an X-Hybrid is installed in the Channel 1 transmit path, or set
to
N (no) if an X-Hybrid is not installed in the Channel 1 transmit path.
This parameter is normally set at the factory, or can be set by the user.
