33. s 33 INSTALLING WHERE TO INSTALL The RTR model is 35 mm DIN rail mountable and FTR is wall mountable Desktop use is also an option The best place for a receiver is a big grounded horizontal metal plane surrounded by as few as possible vertical metal surfaces Antenna is to be installed perpendicular to the metal using angled connector or with extension cord The best coverage for the transmitter is achieved when the receiver has line of sight to the transmitters Every obstacle between the devices will attenuate the signal and thus decrease the range On the other hand metal surfaces will cause reflections which can in some cases increase the range CONNECTIONS Rr isa Device can be connected using USB RS 485 or RS 232 buses Each of these connections will be described in their own chapter below Power supply connections are also described separately in each subchapter By default the device is jumpered to use the USB bus If RS 485 or RS 232 bus is to be used the serial bus needs to be jumpered differently Open the case by pressing in the fasteners on both sides of the RTR970 case The case of FTR970 is opened by removing the screws ANTENNA CONNECTION Antenna is connected to device s BNC connector Antenna is first pushed into the BNC connector by aligning it with two guide posts after which it is turned 90 degrees clockwise Antenna can be removed by turning it counterclockwise after which the antenna can b
