Setting the R3 Communication Module to Ethernet IP Configuration

NOTICE
Proper grounding with a wrist strap connected to ground is required when touching any components within the communication module or contacts on the R3 Communication Module connector .

The R3 Communication Module is shipped from the factory with a serial communication configuration. See the wiring diagram in Figure 41 on page 23.

This section instructs configuring the module to use the Ethernet IP configuration, which allows remote access to the Wi-Fi/GPS user interface, enables remote firmware updates, and allows use of advanced security features available in the R3 Communication Module firmware version 3.0.00512. See the wiring diagram in Figure 42 on page 24.

To configure the R3 Communication Module for Ethernet IP wiring, WAN traffic must be routed through the Wi-Fi/GPS module. Follow these steps to convert the R3 Communication Module from the serial communication configuration wiring to the IP configuration module wiring:

STEP 1 .

At the communication device, unplug the RJ45 cable that runs between the communication device and the control module. See Figure 14 on page 11.

Setting the R3 Communication Module to Ethernet IP Configuration

The communication module can be installed from a bucket truck with the module handling fitting attached to a suitable hookstick.
CAUTION
The communication module is heavy, weighing more than 26 pounds (12 kg) . S&C does not recommend removal and replacement from the ground using an extendostick . This may cause minor injury or equipment damage . Remove and replace the communication module from a bucket truck using the module handling fitting attached to a suitable hookstick .

Follow these steps to install the communication module:

STEP 1 .

Inspect the wiring connectors and insertion guides of the communication module and communication module bay for damage. See Figure 36.

STEP 2 . Push the handling fitting into the module latch and simultaneously turn the fitting 90 degrees counterclockwise.

STEP 3 .

Position the communication module so the alignment arrows line up, and insert the module into the left bay of the base as shown in Figure 37. Push very hard to engage the connectors.

STEP 4 .

While pushing up on the hookstick, rotate the handling tool 90 degrees clockwise (as viewed from the underside of the base) to close the latch. Then, remove the fitting.

Interface Pinouts
The RS-232 Radio Maintenance Port of the R3 Communication Module is configured as data-terminal equipment. See Figure 38 on pages 21 and Figure 39.
The R3 Communication Module Ethernet ports use RJ-45 connectors with the pinout shown in Figure 40. They are auto-sensing for assignment of transmit and receive lines (no crossover cables required) and autonegotiate for 10-Mbps or 100-Mbps data rates, as required by the connected device.
