3.2 Communication Options
The WattStation has different types of TCP/IP communication interfaces to the customer: Cellular router,
integrated WiFi module or CAT5
3.2.1 Integrated Ethernet communications port
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. If the star configuration is not desired,
the customer can use the 4 port Ethernet switch that is standard in all EVSE models to daisy chain
CAT5e cables from one EVSE to another.
WattStation Ethernet ports support only 10BASE-T (10 Mbit/s) or 100BASE-TX (100 Mbit/s) network
speeds. Installation on networks running at 1000BASE-T (100 Mbit/s) will require that the networks be
configured to support devices that operate at 100 Mbit/s.
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.
3.2.2 Integrated WiFi Module option
A Pedestal 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 numbers.
Note that a Pedestal WattStation that has the WiFi radio and antenna installed cannot utilize the
cellular option.
3.2.3 Cellular router option
The cellular router will provide wireless communication for a single or group of EVSEs over a cellular
provider’s network. A customer can choose to put a cellular router into each EVSE they have at a
location or they can add one cellular router into a group of EVSEs and daisy chain the EVSEs together
using the CAT5.
