GBK51948 RHINO2
Installation Manual Issue 5
(manufacturer part no. 39-00-0039 — Dynamic part no. GCN0771).
In Wizard, set Prog/Inh Pin Function , which can be found under the Multi-
function Inputs Configuration group, to None.
7.7.3 Protocol
7.7.3.1 Configuration
Communications is unidirectional, using a single wire from the RHINO2 to the external data
logging device and is set at 9600 baud, with 1 stop bit, and no parity (9600/8-N-1).
7.7.3.2 Data transmission
The following outlines the transmission schedules for both the Full Data packet and the
1 Hz Data packet. The 1 Hz Data packet is transmitted only if enabled.
7.7.3.2.1 Full Data packet transmission
Full Data is scheduled to transmit periodically on each single-wire communication pin in
data packets, the first of which starts approximately 10 seconds after the scooter is
powered up. A packet is transmitted:
l
once every 60 seconds if the scooter is driving or is connected to a charger and
charging;
l
once every 60 minutes (first 6 hours only) if the scooter is not driving and the key is in
the On position;
l
once every 12 hours while the scooter controller is in Low Power Mode — see 5.11
Controller Power Modes.
In addition to the scheduled transmissions, a packet is transmitted when any one of the
following changes state:
l
key status
l
inhibit status
l
active fault status
l
park brake status
l
sleep status
l
charging status
Following an unscheduled transmission (listed above), the next scheduled transmission
begins after the regular fixed interval (60 seconds, 60 minutes or 12 hours) starting from
the time that the unscheduled transmission began transmitting.
7.7.3.2.2 1 Hz Data packet transmission
If the 1 Hz Data packet transmission is enabled (see Enable 1Hz Data), it is transmitted,
nominally, once every 8 seconds. Between transmissions, the values of battery voltage,
ambient temperature, and motor current are sampled once a second and then stored in
buffers. Note that these buffers can hold more than 8 sets of samples in case the
transmission needs to be delayed, because, for example, a Full Data transmission is in
progress.
