## Connector Pin Assignments

### GPS Transceiver

GPS Transceiver Connector Pin Assignments
Pin | Description | Pin | Description

### POWER Data Cable

DIN PIN Twisted Pair | COLOR | SIGNAL | RJ-45 PLUG PIN
2 7 | BLUE WHITE / BLUE | +24 VDC -24 VDC | 4 5
6 8 | WHITE / BROWN BROWN | +24 VDC -24 VDC | 7 8
5 3 | WHITE / ORANGE ORANGE | Rx+ Rx- | 1 2
1 4 | WHITE / GREEN GREEN | Tx+ Tx- | 3 6
Color codes are for reference only

### Ethernet Port Connector

The Ethernet connector supports 10/100 Base-TX Ethernet serial data using one 8-pin modular jack connector. This port allows Ethernet data to be passed across the hop.

Ethernet Port Connector Pin Assignment Description
Pin | Description | Signal Direction
1 | Rx Data In + | Input
2 | Rx Data In - | Input
3 | Tx Data Out + | Output
4 | * (connected to cross-talk suppression circuits) |
5 | * |
6 | Tx Data Out - | Output
7 | * |
8 | * |

### T1/E1 Cable

Notes:

1. The maximum recommended cable length for a T1/E1 cable is 655 feet (approximately 200 M) .

2. To connect the shielded connector to the shielded cable, the wire inside the cable’s metal sheath must be soldered to the metal case of the connector (at one end only).

3. When Installing the connector and weatherseal strain relief onto cable, do not tighten to the cable until final installation.

4. Connect to the T1 circuits using properly shielded 8-pin modular (RJ-48C) connectors; connect to the E1 circuits using properly shielded 8-pin modular (RJ-45) connectors.

The color code of the Ethernet cable used between the power supply and the radio depends upon the particular QuickBridge radio. For example, the color code of the Ethernet cable used between the power supply and the radio has been changed to the standard EIA 568B wiring color code. See the illustration at the bottom of the next page.

Normally this does not present a problem since the cable is wired the same end-for-end; just the colors have changed. When using a lightning protector, however, the color code of the cable must be noted to make sure that the lightning protection is connected properly. Incorrect wiring can cause damage to the lightning protector. Here are the two different color codes.

Signal | RJ45 Pin# | DIN Pin# | Original Wiring Color | 538B Wiring Color
Rx+ | 1 | 5 | Green | White / Orange
Rx- | 2 | 3 | White / Green | Orange
Tx+ | 3 | 1 | Blue | White / Green
+V | 4 | 2 | Orange | Blue
-V | 5 | 7 | White / Orange | White / Blue
Tx- | 6 | 4 | White / Blue | Green
+V | 7 | 6 | Brown | White / Brown
-V | 8 | 8 | White / Brown | Brown

The color code that a cable is using can be identified by either looking at the color of the wire in pin one of the RJ45 connector (the pin on the left with the tab facing down and the cable coming towards you). If the wire in pin 1 is Green, then you have the original color code, if the wire is White / Orange then you have an EIA 568B wired cable.

Alternatively, if you do not have access to the RJ45 (for installed systems), you may reference the part number and revision label on the cable that is usually near the DIN connector. Refer to the following table to determine which color code cable you have based on the cable.
