The CMS Family is a range of high performance modems offering Rx, Tx and Rx/Tx functionality using Narrow Band FM at VHF and UHF frequencies. RF Power levels range for 0.1 watt to 5 watts and user interfaces may be TTL or RS232. All units offer fully synthesised frequency selection.
All the CMS Range utilise the advanced Soft Modem functions built into the firmware allowing simple configuration and adaptation to application requirements. This function can be bypassed where the units are required to link into existing systems using external modem functions.
