Page 7: Introduction / Overview
To communicate with T24 devices a base station is required. Base stations will offer RS232, RS485 and USB interfaces. Refer to the Base Station section T24-BSi and T24-BSU for details on connections and interfacing. 2.4GHz Radio General Communicating with T24 Devices To communicate with T24 devices a base station is required. -

Page 16: T24-Bsi And T24-Bsu [Base Station]
Addressing is vital as it is this that distinguishes between base stations. When using USB base stations you may only ever have one T24-BSu connected to a PC at any time. Using T24-BSi will allow multiple USB base stations to be connected to single PC. Unique Addresses are again required in this instance. -
Page 17: Connection
At any rate below 230400 is may be possible to lose packets at high data rates as the serial cannot keep pace with the radio transmissions. If USB is not selected as the interface (Switch positions 5 to 7) then this switch position selects whether the serial interface is RS232 or RS485. 232/485 RS232 RS485 Mantracourt Electronics Limited T24 Technical Manual... -
Page 18: Interfaces
RS485 is a bus master system and is not ideally suited to full communications with devices when multiple • devices are providing data. This is fine for the normal operation of data acquisition but it is recommended that only the device to be configured is active during configuration. Mantracourt Electronics Limited T24 Technical Manual... -
Page 19: Usb Communications
Connection to the base station will be either a captive USB cable (T24-BSu) or a USB socket B for connection using a standard USB A-B cable (T24-BSi). There is an optional cable assembly for the T24-BSi to provide for a USB connection while the device is still fitted to the ABS case. -

Page 22: Installation
Installation The base T24-BSi should be mounted horizontally on a wall or ceiling so that the side face containing the PCB antenna faces the general direction of the target devices. The T24-BSu should also be positioned to present itself to the other radios in a 'landscape' aspect. -

Signal power at the input of the receiver = -64.46dBm Note that although the manufacturer’s data sheet for the chip antenna gives gain as 3dBi Peak, this figure is rarely achieved in practice; between 1 and 1.5dBi is more usual. Mantracourt Electronics Limited T24 Technical Manual... -

So the estimated power at the receiver input is -77.22dBm Refer to Table 1 below that shows the relationship between receiver input power and RSSI, an input level of - 77.22dBm will result in an RSSI between -80 and -85. Mantracourt Electronics Limited T24 Technical Manual... -
