Please follow the steps below for proper setup and channel pairing settings. 1. Firstly, drop the red TX card into the TX box, and secure the antennas on top of the TX card and that of the RX box. Then, connect to the power supply and turn on the RX and TX respectively. 8 2. Connect 2.4G wireless communication between the TX and the RX units. 1On the main menu page of the TX, click on RF Setting to go to the next page and select Channel on this page. The product has 9 channel options under 2.4G communication. Select the channel you want. 2Repeat the above 2.1)operation on RX unit. Select the same channel as that on the TX unit to 9 connect the TX and the RX. 3. When signal bar appears on the RX screen, it means that the TX box and RX box are connected successfully. The information displayed on the screen now is the channel number and signal intensity. 4. Connect and pair 5.8G wireless communication between the TX and RX. Only after 2.4 G connection succeeds can we start connection and pairing under 5.8G 1) On the main menu page of the TX box, Click on WFP Setting to enter the next menu page and select Channel on this page. The product has 12 channel options under 5.8G. Select your channel, and then go back to the main menu page. 10 2) Repeat the above operation (Step3.1)on the RX box, select the same channel as the TX box and then go back to the main menu page. 3) On the main menu page of TX box, click on WFP Setting to enter the next menu page. double-click on Pair on this page, Repeat the same on the RX box. (On the main menu page of TX box, click on WFP Setting to enter the next menu page. Double-click on Pair on this page.) And Wait. 11 4) When the TX screen reads Done and Other, while the RX screen reads Done, it means pairing succeeds between TX box and RX box under 5.8G. 5. Go back to the main menu page. Connect the HDSDI input port of TX box with the camera SDI port, Black Tower is ready for video transmission. 6. In case multiple RXs are required to work simultaneously for the shooting, turn off the power of the above RX box after successful pairing at step 3.4) ,then Click on Other on the TX 12 screen. Get the second RX ready by turning it on, then repeat the above steps 3.2), 3.3), 3.4).to get a new pairing established. Repeat this section to establish more connection and pairing. Trouble shooting In case RX cannot transmit video to monitor properly, please first refer to the following chart for possible reasons and solutions. Malfunction and possible reasons Solutions Continuous display of "waiting for connection"
