2. Single Antenna
The NXR-810 can be used as a base station by sharing an
external antenna connector for both transmitting and receiv-
ing data.
2-1. Modifi cation
1. Using a soldering iron, delete C76 and add C73 and C78
(100pF; C93-0572-05) on the Final unit (A/3).
2. 单天线
使发射和接收信号共用一个外部天线连接器，可以将 N X R -
810 用作基站。
2-1. 更改
1. 在末级单元 ( A /3) 上，用烙铁除去 C76 并增加 C73 和 C78
(100pF;C93-0572-05)。

2. Short-circuit the printed pattern of ANT SW near the
CN204 connector by soldering.
3. Disconnect the pin connector from CN101 of the TX-RX
unit.
Remove the two screws used for securing the BNC con-
nector on the back panel of the unit. Detach the antenna
cable assy. (E30-3418-15)
4. Cut off the coaxial cable of the removed antenna cable
assy on the BNC connector side.
Strip off the insulation of the cut-off coaxial cable to pre-
pare it to be soldered.
2. 以焊接方式将 ANT SW 的印刷图案短接到 CN204 连接器附近。
3. 从 TX-RX 单元的 CN101 断开针脚连接器。
拆下用于将 B N C 连接器固定在单元背板上的两颗螺丝。拆
下天线电缆组件。(E30-3418-15)
4. 切断已拆下的天线电缆组件的 BNC 连接器侧的同轴电缆。
剥下所切同轴电缆的绝缘材料，做好焊接准备。
Strip off the insulation so that
the cable can be soldered.
Cut off the coaxial cable at this point.
