RJ-11 Straight-thru GPS sync cable
An RJ-11 cable is commonly used to connect a device to a phone line. This cable resembles the
RJ-45 Ethernet cable except for a thinner cord and smaller plug. The Canopy system uses an
RJ-11 cable to connect the AP or BH to GPS synchronization. Presuming CAT 5 cable and 6-pin
RJ-11 connectors, the following diagram shows the wiring of the cable for GPS sync.
Pin 1 → white / orange ← Pin 1
Pin 2 → white / green ← Pin 2
Pin 3 → white / blue ← Pin 3
Pin 4 → green ← Pin 4
Pin 5 → blue ← Pin 5
Pin 6 → orange ← Pin 6

7.2.4 Overriding IP Address and Password Setting
Canopy systems offer a plug that allows the operator to temporarily override some AP settings and
thereby regain control of the module. This plug is needed for access to the module in any of the
following cases:
• The operator has forgotten either
− the IP address assigned to the module.
− the password that provides access to the module.
• The module has been locked by the No Remote Access feature. (See Denying All
Remote Access on Page 26 and Reinstating Remote Access Capability on Page 26.)
• Local access is desired for a module that has had the 802.3 link disabled in the
Configuration page of the module.
This override plug resets the LAN1 IP address to 169.254.1.1. The plug allows the operator access
the module through the default configuration without changing the configuration. The operator can
then view and reset any non-default values.
