Communication Options - GE WattStation Installation And User Manual

QR Code
The front cover of the Networked Wallmount WattStation has a
label placed under the top assembly cover, viewable through the top cover. Each QR code holds a
unique serial number in its image. The QR code serial number is stored in the EVSE's SBC (Single
Board Computer).
An EV driver or EVSE owner can use their IPhone and the GE WattStation application to scan the
QR code. Once the QR code is captured, the application will automatically connect to the GE
WattStation Connect and provide the driver or EVSE owner with access and information for the
Networked Wallmount WattStation.

3.3 Communication Options

The WattStation has different types of TCP/IP communication interfaces to the customer: Cellular
router, integrated WiFi module or CAT5
3.3.1 Ethernet communications
TCP/IP communication over an IEEE 802.3 (a.k.a. "Ethernet") compliant network between the EVSE
and customer network is available in all EVSE models. A single CAT5e or better cable can be run
from each EVSE to a network hub, router or switch in a star configuration.
The maximum length of the communication cables is determined by the CAT5e standard, which
stipulates a maximum length of 100 m (328 feet). If longer runs are required, the use of active
hardware such as a repeater or a switch is necessary.
3.3.2 Integrated WiFi Module option
A Networked Wallmount WattStation with WiFi communication incorporates a IEEE 802.11b/g
compliant radio module. EVSE customers that do not select the WiFi communication option will
not receive this radio module. The WiFi module allows the EVSE owner to communicate to their
Building Management System (BMS) or GE WattStation Connect over WiFi. The WiFi module will
have a connection to attach to the EVSE's WiFi antenna. The WiFi module will support IEEE 802.11
b/g networks. Operation on IEEE 802.11n networks will therefore require that the networks be
configured to support 802.11g devices. The WiFi module is disabled when shipped and is enabled
by first connecting to the configuration tool via a CAT5 connection.
The IEEE 802.11b/g compliant WiFi radio is certified as an intentional radiator per FCC Part 15
Subpart C rules and has been granted the following Federal Communication Commission and
Industry Canada (Industrie Canada) identification number.
Note that a Networked Wallmount WattStation that has the WiFi radio and antenna installed
cannot utilize the cellular option.
