DTC COMMUNICATIONS, INC. 11INSTALLATIONAntenna Options Before installing the MiniBox-4, you should also consider antenna options (if you are using RF analog or digital transmission). You have the choice of using one or two patch antennas.Using both patch antennas with the supplied splitter will provide the largest radiation pattern but at a lower gain. Using one antenna will make the radiation pattern directional, but will typically double the gain, which will increase the signal range in that direction.To configure for one antenna, disconnect the coax from the transmitter at the bottom of the splitter and connect the double-female adapter in its place. Connect the cable from the desired active antenna to the adapter. See illustration top right.To configure for two antennas, disconnect the coax from the transmitter at the double-female adapter and connect the splitter (input) in its place. Connect the cables from both antennas to the splitter (outputs). See illustration bottom right.NOTE: Do NOT remove antenna connections with device powered ON!MiniBox-4 Using2 Patch AntennasMiniBox-4 Using1 Patch AntennaSPLITTERRIGHT PATCHANTENNALEFT PATCHANTENNATRANSMITTERSPLITTERDOUBLE FEMALEADAPTERACTIVE PATCHANTENNANON ACTIVE PATCHANTENNATRANSMITTEROne Antenna CongurationTwo Antenna CongurationWAN LOGD

DTC COMMUNICATIONS, INC. 15WI-FI SETUPWARNINGWiFi (802.11g) operates in the S-Band 2.4 GHz.If your MiniBox-4 is equipped with both WiFi and an S, S2, S3 Band transmitter, the transmitter will cause the WiFi system to be intermittent or inoperable. Use either WiFi or S, S2, S3 Band transmitter, but not both at the same time.WiFi may also suffer from interference if used in close proximity to microwave ovens and cordless phones.To setup your Wi-Fi option, complete the following steps: 1. Remove the plastic door from the front of the camera to expose the PCMCIA slot.2. The 802.11 Wi-Fi card is shipped in the Accessory Bag--attached with Kapton tape to the PCMCIA Adapter. Push this assembly gently but firmly into the slot on the front of the camera as shown. The gold connector must be on the left.3. Access the Wi-Fi signal with a Wi-Fi-equipped computer via a web browser (see page 20).4. To remove the card and adapter assembly, press the eject button to the right of the PCMCIA slot.W Camera Latency: In applications where continuous or frequent camera control commands are sent or if controlling the camera using two sources (RF TX & WiFi) at the same time, latency may build due to the buffering and processing of these commands. This latency will be observed as the camera being slow or non-responsive to commands. To minimize this effect, DTC recommends controlling the camera with one source at a time and lowering the frame-rate to 5 fps for optimum viewing and operation.

DTC COMMUNICATIONS, INC.18OPERATIONConcealed Camera PortsThere are three concealed camera ports on the Utility Box. Each port is disguised with an ELECTRICAL PANEL IN USE label. Keep the label surface clean and free from scuff marks. Make sure nothing blocks this area.A combination of two labels and an interior screen are installed per window. Three additional labels (one per window) are also included in the accessory kit. The installed label set and interior screen will provide the best camera performance while balancing covert appearance issues, such as reflection and light penetration from the other windows. The additional (accessory bag) labels can be customer-applied if desired. You must be willing to accept some honeycomb effect in the video at lower camera zoom settings in order to cover up the tinted glass area of the windows. Ventilation and Thermal ConsiderationsThe Utility Box has a louvered exhaust vent on the back and a wire mesh intake vent on the bottom of the enclosure. A cooling fan is mounted inside of one of these ports. The cooling fan and heater run automatically to keep the MiniBox-4 operating temperature between –20C (-4F) and +50C (122F). Foam mesh filtration protects against water/dirt invasion. Optional Analog and Digital transmitters feature a thermal shut-down circuit to protect the transmitter if the inside of the MiniBox-4 gets too hot. Always remove obstructions from the vents to ensure good air flow. Vacuum the bottom vent to remove excess dust, Remove the rear louvers, clean and replace the foam filter if needed.Do NOT block airow to vents at back and bottom of MiniBox-4AN LOGWD
