KEPLIP-1.0 TCP/IP based L-band Modulator KEPLIP-1.0-DS-Rev 4.3 - Nov 10, 2102 General Description
Current protocol standard is 802.11g.
L-band modulator is high demand product in Internet Age. It is used for transmitting digital data for multimedia applications. L-band frequency range is designated from 950Mhz to 1750Mhz.
However other synchronous digital data source up to 2Mpbs may selected having RS422 interface. KEPLIP-1.0 is targeted to be indoor use with 0ºC to 50ºC temperature range.
Data Baud rate preliminary depends on available bandwidth. Presently it is available up to 2Mbps. Streaming multimedia normally uses 384Kbps to successfully transmit legible information in real time. The product is developed in association with Space Application Center-ISRO. The product is currently targeted for edusat program. Data source is promoted to be an IBM PC ugh TCP/IP Ethernet port. The product is currently targeted for edusat program. Data source is promoted to be an IBM PC through TCP/IP Ethernet port
It has power supply requirement of 230V AC±15% VAC 47~52Hz. Features ♦ ISRO Approved Technology ♦ Indigenous ♦ High Accuracy ♦ Tight Inter changeable Tolerance ♦ Excellent Long-Term Stability ♦ Predictable Performance ♦ Wide Supply Voltage
