LOOPBACK Command
The LOO command is used for testing the MIRRORED BITS communications
channel for proper communication. For more information on M
IRRORED BITS,
see Appendix G: Mirrored Bits Communications. With the transmitter of the
communications channel physically looped back to the receiver, the M
IRRORED
B
ITS addressing will be wrong and ROK will be deasserted. The LOO command
tells the M
IRRORED BITS software to temporarily expect to see its own data
looped back as its input. In this mode, LBOK will assert if error-free data are
received. The LOO command with just the channel specifier, enables looped
back mode on that channel for five minutes, while the inputs are forced to the
default values.
=>>LOO A <Enter>
Loopback will be enabled on Mirrored Bits channel A for the next 5 minutes.
The RMB values will be forced to default values while loopback is enabled.
Are you sure (Y/N)?
=>>
If only one MIRRORED BITS port is enabled, the channel specifier (A or B) may
be omitted. To enable loopback mode for other than the 5-minute default, enter
the desired number of minutes (1–5000) as a command parameter. To allow the
loopback data to modify the RMB values, include the DATA parameter.
=>>LOO 10 DATA <Enter>
Loopback will be enabled on Mirrored Bits channel A for the next 10 minutes.
The RMB values will be allowed to change while loopback is enabled.
Are you sure (Y/N)? N <Enter>
Canceled.
=>>
To disable loopback mode before the selected number of minutes, re-issue the
LOO command with the R parameter. The R parameter returns the device to nor-
mal operation. If both M
IRRORED BITS channels are enabled, omitting the chan-
nel specifier in the disable command will cause both channels to be disabled.
=>>LOO R <Enter>
Loopback is disabled on both channels.
