Drive Select is implemented by shorting one of the four connections, using the Drive Select Jumper. The W5 location is used for radial configurations. The drive is selected at all times with the W5 jumper installed. If jumper configurations are changed, power should be cycled off and on, so that the microprocessor can recognize the new configuration. Terminator Resistor ------------------- The terminator resistor pack, located on the +--------+ logic circuit board should be installed in the |********| ^ last drive of the daisy chain. All other +--------+ | drives on the interface must have the ++++++++++ resistor pack removed. For a radial configura- +--------1 tion, all drives should have the terminator resistor pack installed.
