Your Trango SDR900H System Your Trango SDR900H System Congratulations on choosing Trango Systems to fulfill your wireless video needs. Unpack your system carefully. If any items are missing, notify your sales representative. If an item appears to be damaged from shipment, replace it into its packing material and notify the shipper. -
Page 7: System Description
The SDR900H radios come pre-mounted in a NEMA 4X aluminum enclosure. This permits the unit to be mounted outdoors. Important! The SDR900H enclosures are designed to be mounted on a steel pole with a maximum diameter of 2 3/8”. The pole must be securely mounted into the ground, or to a structure to prevent movement of the antenna and camera in windy conditions. -

In some cases it may be necessary to control more than one camera from the same console. In this case, one SDR900H can be used to transmit a control signal, while a pair of SDR900H radios at the cameras will be used to receive the transmitted serial data signal. -

1) Terminal Block – Two lugs serve as the input for simplex data from 1200 to 57600 bps. When transmitting under RS485/422 protocols, data wires from the PTZ controller will connect to the RX+ and RX- of the SDR900H terminal block. On the camera side connections are made to TX+ and TX- on the SDR900H terminal block. -

Your Trango SDR900H System Example: SDR900H set to 9600 baud, 8 data bits, no parity, hopping channel 0, and address 1. Figure 5: SDRLink Programming Software 7) Select the proper baud rate and parity to match the settings for your camera and controller. -
Page 12: Troubleshooting
Troubleshooting Interference or intermittent operation • Make sure all SDR900H radios are properly grounded. • Heavy equipment, such as industrial roof-mounted air conditioners or fan motors, in close proximity to the radio or cables may cause interference, especially when operating in RS232 mode. - Page 13 Plug the supplied programming cable, CBLDAT-1, into J2 on the radio. Power the radio on, and connect to the radio using SDRLink. • Open SDRLink and run Restore Defaults. Page 11 Trango Systems, Inc. SDR900H Rev. B...
