CSS 'CADDY' SERIES PRODUCTS
The CSS 'Caddy' Series is a range of equipment in CD‐ROM caddy form factor designed to compliment modern Software defined Radios (SDRs) from manufacturers such as iRF Solutions, CyberRadio Solutions, Leonardo DRS, Detica, Silver Palm and many more, and form the current focus of our new developments. Designed for extended remote or autonomous operation in small covert or unmanned installations, these are rugged, high-reliability units with comprehensive control and BITE using SCPI commands over Ethernet or RS232/TTL serial, browser GUI or SNMP.
