Page: 5 of 19 2.3 Typical application 2.3.1 For base： The cordless base using the MD-1562 contains a base band section & a RF section. The antenna(s) will be located outside the module PCB area. To compose a base, the module will need the additionally hardware interface to support line interface、power supply、handset charger interface...
Page: 6 of 19 2.3.2 For data application： The MD-1562 for data application can be executed as a MD-1562 base, combined with one co-processor, which then by the control of the module able to send data back and forth using the up to 32 Kbits/s air interface. It is possible to establish a data link from up to five handsets to one base and routing the data via the UART interface. However, the UART interface has a limited transmission speed up to 115.2Kb/s baud rate. If more data connections are active at the same time and exceeding the capacity of the serial bus, the bandwidth of the bus is shared equally between the data connections. For the base with MD-1562, it is possible to send data from one handset to another. It is possible to send Low Speed (6.4Kbits/s) data between two handsets in an intercom through the base unit.
