IV. Installing the Antenna
The ETP-CI-4G-GSM Cellular Interface includes a remote-mounting MIMO antenna. The remote-mounting
MIMO antenna should be attached to the Talk-A-Phone enclosure (e.g., ETP-MTE-W, ETP-MT/R-SOLAR, ETP-
MT/R-PCS, etc.) via the built-in antenna mounting hole. To install the remote-mounting MIMO antenna, please
follow the separate antenna mount instructions included with the remote-mounting MIMO antenna.
Figure 1. An example of mounting the remote-mounting MIMO antenna onto the cap of an ETP-MT/R-PCS tower.
The remote-mounting MIMO antenna will be connected to the ETP-CI-4G-GSM Cellular Interface through the
ports listed in Section V.2.
V. Installing the Cellular Interface
1. The front panel of the ETP-CI-4G-GSM Cellular Interface provides the following:
(1) Cellular signal strength indicator;
(2) LED indicators for POWER, STATUS, CELL, and GPS;
(3) DATA port reserved for future use;
(4) MODE button reserved for future use;
(5) RESET button for rebooting the cellular interface;
(6) PHONE-FXS port for connecting to an ETP-500 Series Phone.

2. The rear panel of the ETP-CI-4G-GSM Cellular Interface provides the following:
(1) Input terminal for 12VDC;
(2) CELL 1 connector for remote-mounting MIMO antenna;
(3) CELL 2 connector for remote-mounting MIMO antenna;
(4) GPS connector for remote-mounting MIMO antenna;
(5) SIM slot for micro-SIM (3FF) card;
(6) CONFIG port for a mini-USB connection (for Talkaphone Technical Support purposes only).
Figure 3. Rear panel of the ETP-CI-4G-GSM Cellular Interface.
3. Insert the micro-SIM (3FF) card into the slot labeled SIM (see Figure 3 –Item 5).
IMPORTANT: The orientation of the micro-SIM card should be angled notch entering the slot first with
the metal contacts facing down toward the mounting flanges.
4. Using a plastic spudger or a small flat head screwdriver, push the micro-SIM card into the slot until a
click is heard. To remove the micro-SIM card, push the card until a click is heard and the card springs
out of the slot.
5. Connect the cables from the remote-mounting MIMO antenna to the CELL 1, CELL 2, and, GPS
connecters (see Figure 3 –Items 2, 3, and 4.On the built-in cable assembly of the remote-mounting
MIMO antenna, there are two (2) cables labeled CELL –connect those cables to the CELL 1 and
CELL 2 connectors. Any of the two CELL cables can connect to either connector.
6. Connect the ETP-500 Series Phone to the PHONE-FXS port.
7. If the interface is being powered by an SLR Series (solar) kit, connect the LOAD terminals of the solar
controller to the appropriate polarity markings on the POWER terminal (12VDC input) of the ETP-CI-
4G-GSM Cellular Interface. Otherwise, connect a 12VDC power source appropriately with respect to
polarity.
8. Using the built-in mounting flanges, attach the ETP-CI-4G-GSM Cellular Interface onto the internal
mounting panel of the Talk-A-Phone enclosure (e.g., ETP-MTE-W, ETP-MT/R-SOLAR). The ETP-CI-
4G-GSM Cellular Interface should be mounted so that the 12VDC input terminal is on the lower right
corner (i.e. toward the Earth).
