MIRRORED BITS Communications
Settings
the modem will deassert if the channel has too many errors. The modem uses
the meter RTS signal to determine whether the new or old M
IRRORED BITS
protocol is in use.
Seconds to Mirrored Bits Rx Bad Pickup(1-10000) RBADPU= 60 ?
Use the RBADPU setting to determine how long a channel error must last
before the meter element RBADA is asserted. RBADA is deasserted when the
channel error is corrected. RBADPU is accurate to ±1 second.
PPM Mirrored Bits Channel Bad Pickup(1-10000) CBADPU= 1000 ?
Use the CBADPU setting to determine the ratio of channel down time to the
total channel time before the meter element CBADA is asserted. The times
used in the calculation are those that are available in the COM records. See the
COM command in the instruction manual for a description of the COM
records.
Mirrored Bits Receive Identifier(1-4) RXID = 1 ?
Mirrored Bits Transmit Identifier(1-4) TXID = 2 ?
Set the RX_ID of the local meter to match the TX_ID of the remote meter. For
example, in the three-terminal case, where Meter X transmits to Meter Y,
Meter Y transmits to Meter Z, and Meter Z transmits to Meter X (see
Table G.2).
Mirrored Bits Receive Default State(string of 1s, 0s or Xs)
87654321
RXDFLT=XXXXXXXX
?
Use the RXDFLT setting to determine the default state the MIRRORED BITS
should use in place of received data if an error condition is detected. The
setting is a mask of 1s, 0s, and/or Xs (for RMB1A–RMB8A), where X
represents the most recently received valid value.
