TotalFlow Protocol at 9600 with Sleep Mode
For reliable operation with TotalFlow meters, use the default settings for
9600 with the following alterations:
HOPTIME 28—Allows large data packets
FEC OFF—Improves store-and-forward performance for a large contin-
uous data stream
BUFF ON—Ensures “ungapped” 4-second polls if unit is in sleep mode
Operation at 115200 bps
Burst throughput at 115200 bps is supported at all settings. The radio will
always buffer at least 500 characters. Sustained throughput at 115200 bps is
only possible when the data path is nearly error-free and the operating settings
have been properly selected. For sustained operation at 115200 bps, use the
following settings:
SAF OFF, FEC OFF, REPEAT 0, RETRY 0, HOPTIME 28.
Baud Rate Setting
The default baud rate setting is 19200 bps to accommodate most systems. If
your system will use a different data rate, you should change the radio’s data
interface speed using the
BAUD xxxxx abc command (Page 41). It should be set
to the highest speed that can be sent by the data equipment in the system. (The
transceiver supports 300 to 115200 bps.)
Radio Interference Checks
The radio operates in eight frequency zones. If interference is found in one or
more of these zones, the
SKIP command (Page 53) can be used to omit them
from the hop pattern. You should also review 7.0 DEALING WITH INTER-
FERENCE, when dealing with interference problems, when interference
problems are encountered.
5.1 How Much Output Power Can be Used?
Refer to the Antenna Gain/Power Data charts at the front of this manual for
approved antenna types and maximum RF power settings for the transceiver.
You must ensure compliance with all applicable rules for the country of oper-
ation before placing the transmitter on the air.
