MISCELLANEOUS TECHNICAL NOTES |
|
The CRD-5300 will not operate without an attached battery back-up or an uninterruptible power supply. Also, terminating drive buses by installing on-board resistors is not recommended because the end drive on the bus cannot be removed during a "hot swap" without leaving the bus unterminated. |
