MIRRORED BITS Protocol for the Pulsar 9600 Baud
Modem
The user indicates that a Pulsar MBT modem is to be used by responding
“MBT” to the RTS/CTS setting prompt. When the user selects MBT, the baud
rate setting will be limited to 9600 baud.
NOTE: The MBT mode will not work
with PROTO=MB8A or MB8B.
The MIRRORED BITS protocol compatible with the Pulsar MBT-9600 modem
is identical to the standard M
IRRORED BITS protocol with the following
exceptions:
The relay injects a delay (idle time) between messages. The length of the
delay is one relay processing interval.
NOTE: An idle processing interval
guarantees at least 19 idle bits at
9600 baud in an SEL-321 Relay with
the system frequency at 65 Hz.
The relay resets RTS (to a negative voltage at the EIA-232 connector) for
M
IRRORED BITS communications using this specification. The relay sets RTS
(to a positive voltage at the EIA-232 connector) for M
IRRORED BITS
communications, using the R6 or original R version of M
IRRORED BITS.
