GENERAL DESCRIPTION
The Dataradio TSLM is a transparent, real-time wireless modem designed to replace wire
lines in SCADA, telemetry, and any other information and control applications that utilize
RS-232 serial data messaging. The TSLM uses advanced digital modulation and signal
processing techniques to achieve exceptionally high throughput efficiency using licensed
narrow band radio channels.
The TSLM is available in many frequency bands and regulatory formats, to suit spectrum
band requirements in various continental regions. The range is designed for both fixed point
to point, and multiple address or point to multipoint systems.
2.2.1
Physical Description
The TSLM consists of a logic printed circuit board (PCB) that includes the modem circuitry
and a separate radio module. The unit is housed in a nickel-plated, formed steel case. The
front panel includes the DE-15 data connector and a BNC antenna connector, as well as two
multi-colored LED indicators. Power connections are made through the DE-15 data
connector. The unit is not hermetically sealed and should be mounted in a suitable
enclosure where dust and/or a corrosive atmosphere are anticipated. There are no external
switches or adjustments. Operating parameters are set using TSLM Programming Software.
