P664 Temperature
View the temperature in °C as registered by the transducer's integral temperature sensor
(Echomax series). If a non temperature sensing transducer is being used, the fixed
temperature (P661) is displayed.
P740 Peripheral Communication
Determines the ASCII message format.
The MiniRanger Plus Rack and Panel units provide a proprietary 20 mA bipolar current
loop for communication with the Siemens Milltronics BIC-2 peripheral device.
The MiniRanger Plus uses simplex convention communication protocol. Data messages
are continuously transmitted at regular intervals (no poll is required) at 4800 baud. All
data is transmitted in structured messages of ASCII characters consisting of 8 data bits,
no parity, and 1 stop bit.
If Peripheral Communications (P740) is set for "formatted" messages, a comma is inserted
between each message field (except immediately preceding the "End of Message"
characters).
