This prevents data from echoing back from the BB-CANOP, but allows the nodes to respond back.Ī 10-30 VDC external power source is required (not included, sold separately). It also disables the driver on the receive side for the low bit plus a maximum of 2µ seconds. Bit-wise enable only enables the driver on every low bit received. Model BB-CANOP is bit-wise enable, allowing it to automatically adjust for different baud rates. If the BB-CANOP is not at the end of the network, it should not be terminated. Space is provided on the board for a termination resistor on each side, R6 and R8 (120 Ohm resistor recommended). The BB-CANOP creates two new ends to the CAN network. Networks that are not properly terminated may experience data errors or miss data completely. Isolation prevents the two biggest issues plaguing DC power systems and the devices on them ground loops and ground potential differences. It is protocol independent, allowing it to work with different CAN protocols and frame lengths.Īccording to the CAN specification, the CAN network must be terminated at both ends. The fiber optic cable is not susceptible to interference caused. The BB-CANOP provides 2,000 VDC of optical isolation to separate and protect critical segments of the system from the rest of the CAN Network. The units can be used in areas of high electrical noise or in and out of RF shielded enclosures. Model BB-CANOP increases the node capacity of CAN (Control Area Network) systems while protecting CAN networks from component destroying surges and transients. We address the issue of ensuring the integrity and privacy of communications in optical networks in this paper. I understand that this authorization is subject to revocation at any time, except to the extent that Allegheny Health Network has already taken action in reliance upon it.
