A button cap may be fitted to the non-illuminated button if alternative labelling is required or a height of 12.5 mm has to be reached. The labelling on the button cap is visible through a window in the deco film. The button cap may be exchanged to modify the labelling. ...

These "st&-alone" radio modems incl. integrated PCB-antenna permit a "half-duplex" operation of digital data in the TTL RS-232 format. It is possible to connect the module directly to the interface to a UART of an external micro-processor or to a serial port of a PC by means of the W 232 adapter. Its simple handling does not require any experience in the HB-area. No restriction in the size of the data packets. ...

These multi-channel transceivers are a simple & economical solution for a wireless data transmission at high data rates. The integrated micro-processor can be controlled with TTL logic RS-232 & generates the data packets on its own. Thereby, the user does not have to take care of the programming of software routines & the transmission management. Via the initialization of the internal registers the frequency channels, the serial data rates (9600-19200-38400-57600-115200 bps) & the output power (RF power from -8 to +10 d Bm) can be set. It is possible to select different speeds for the RS-232 signals of two modules. By means of an internal buffer storage in the module, the data can be transmitted with data packets of max. 240 bytes packet length. Ranges (LOS) of 300 m at an optimum antenna adjustment are possible. ...
