Single mode dual GPI and data fibre transceiver card with LC connectors,, * RP for closed relay GPI = open GPO,, The BC720 is a transceiver card allowing the transmission and reception of 4 independent GPIO signals plus 4 RS232 or RS422/485 level signals via fibre optic cable using two independent wavelengths. The 4 GPIO input signals are TTL level inputs with the 4 GPIO outputs provided via isolated relay contact closure.,, The BC720 will also operate in mixed mode allowing RS232 to RS422/485 links, thus eliminating the need for external mode converters.,, All Bluebell cards are designed to maintain maximum signal path integrity, providing excellent jitter-free optical transport.,, The BC720 is available in multimode and single mode versions to suit any fibre application.,, The BC720 occupies a single slot in the 19" 3RU rack chassis BC100 which can accommodate up to 15 single-slot cards. This dual functionality enables the transmission or reception of up to 30 video channels from a single 3RU chassis., Signal and card monitoring is achieved via SNMP monitoring in the BM101 network card., Alternatively, GP output alarms can be triggered via the BM100 module.,, For stand-alone applications, the BC720 can be housed in a robust individual enclosure.,,, Specifications,,,
