Description
The KAPPA modem module is a highly integrated RF modem and intelligent controller with an
ultra simple SIL connection footprint. The KAPPA modem module can achieve a wireless serial
data link at up to 57K6bps over 500m range. Range may be further extended with a suitable
antenna.
The user interface is standard RS232, operating at low voltage. All RF operation is automatically
controlled (with error checking etc) so the KAPPA can be treated as a simple communications
device. Possible applications include one-to-one and multi-node wireless links used for car and
building security, EPOS, inventory tracking, remote industrial process monitoring and computer
networking. Because of their small size and low power requirements these modules are also
ideal for use in portable, battery-powered applications such as hand-held terminals
The KAPPA modem module is fully compatible with RF Solutions’ ZULU series of modem
modules.
