JOLTER TECHNOLOGIES COMPANY [ AXIS ’ 3.375") Figure 1 General: AXS550 transceivers represent an innovative leap in digital signal processing techniques combined with over a decade of spread spectrum experience. AX550's can both transmit and receive spread spectrum messages to provide communication data links with superior RF performance. AXIS transceivers have four digital external event inputs. The AXS550-485 also provides an RS48S interface and the AX350 provides a TTL logic level serial interface.
