CSI interface option is implemented using a single printed circuit board plugged into the option slot within the 9914 The SCSI interface bus is connected either via a shielded connector at the rear of the 9914 or directly to a 50 way 3M type plug on the board Single ended differential and dual variants are available 1 7 Technical Description The 9914 Tape Unit is constructed around an aluminium alloy deck casting which is machined to accommodate the mechanical sub assemblies and hinged in a box section tray which also carries the electronic sub assemblies Access to the tape path area for routine cleaning is by way of a hinged tape path cover revealing the entire tape path when lifted The operator may use the transparent window in the loading door to check the presence of a tape reel or observe tape motion The 9914 has a short tape path using one tension arm which returns to a rest position in the absence of tape tension to simplify the tape lacing path When the self loading procedure has been initiated the tape reel is centralised by the reciprocating action of the hub and then clamped The tape is then threaded through the tape path taken up on the take up reel tensioned and moved forward until BOT is reached without any operator involvement The fixed take up spool is of a special Company design to enable this loading procedure To gain access to the tape path when mounted in a rack personnel may release the deck latches and pu
