7.7 Status Information — Single Wire Communications
This section describes how to connect an external, third-party data logging device to the
RHINO2 single wire communication pins and read the scooter's status information.
7.7.1 Status information overview
The RHINO2 controller transmits scooter status information in packets from two single-
wire communication pins — see Physical interface. There are two packets available:
l
Full Data packet
l
1 Hz Data packet
The Full Data packet is transmitted always; the 1 Hz Data packet is optional and only
transmitted if enabled.
Note
1 Hz refers to the sampling frequency of the data, not its transmission rate. 1 Hz Data is transmitted, nominally,
every 8 seconds when enabled. See 7.7.3.2.2 1 Hz Data packet transmission for more information.
For each Full Data packet transmission, the following information is provided
1
:
l
Charger inhibit status
l
Key switch status
l
Active error code
l
Battery gauge estimate
l
Speed limit
l
Driving status
l
Pin status (TH4, TH6, TH12 and TH14)
l
Month of manufacture
l
Year of manufacture
l
Serial number
l
Controller current rating
l
Time controller powered up
l
Controller power up count
l

l
Internal condition code
l

l
RHINO2 software version / revision
l
Battery voltage

Note 1: Battery voltage, ambient temperature and motor current data are only available in the Full Data
packets when the 1 Hz Data transmission is disabled.
For each 1 Hz Data packet transmission, the following information is provided:
l
Battery voltage
l
Ambient temperature
2
l
Motor current
Note 2: This data is sampled from an optionally installed, external NTC thermistor.
