Description

BC720 GPI and Data Transceiver Card GPI, RS232, RS422/485 pdf icon

The BC720 is a transceiver card providing for the transmission and reception of 4 x independent GPIO signals plus 4 x RS232 or RS422/485 level signals via fibre optical cable using two independent wavelengths. The 4 x GPIO input signals are TTL level inputs with the 4 x GPIO outputs provided via isolated relay contact closure.

The BC720 will also operate in a mixed mode allowing RS232 to RS422/485 links to be made eliminating the need for external mode converters.

All Bluebell cards are designed to retain maximum integrity of the signal path offering excellent jitter free optical transport.

The BC720 is available in multimode and singlemode variants to suit any fibre application.

The BC720 occupies a single slot in the BC100-3RU 19″ rack-mounting frame which can hold up to 15 single slot cards. This dual functionality allows up to 30 channels of video to be transmitted or received from a single 3RU frame.
Signal and card monitoring is achieved through 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 an individual rugged enclosure.
