DETAILED DESCRIPTION OF EACH TYPE OF CABLE ------------------------------------------ All "bussed" mass-termination cable should have conductor #1 on the right side. Recall that the Twist'n'Flat cable indicates conductor #1 by the color DARK BROWN, and the Flat NO TWIST cable indicates conductor #1 by the color RED. All mass-termination cable-mount connectors should have pin #1 on the top of the right side. Recall that these connectors indicate pin #1 with a V-shaped notch. All cable descriptions have lengths specified starting with the BOTTOM connector. 1. Front Panel Specific Backplane Bus This cable provides the Specific Backplane Bus to the topmost 7 Application Cards in the Level 1.5 Backplane. It receives the Specific Backplane Bus from the Level 1.5 Patch Panel. This cable should be made from a 23" long piece of 64 conductor Flat NO TWIST cable. It must have 8 connectors spaced in the following relationship (lengths given connector-to-connector before folding for strain relief): the 7 lower connectors spaced 2_1/8" apart, with the top connector 9_1/8" away from the next-to-top connector. The 7 lower connectors plug into the Front Panel Specific Backplane Bus connector of the topmost 7 Application Cards of the Level 1.5 Backplane, and top connector plugs into the front of the Level 1.5 Patch Panel connector labelled "CBUS." 2. Back Panel Specific Backplane Bus This cable provides the Specific Backplane Bus to the lowest 7 Application Cards in the Level 1.5 Backplane. It receives the Specific Backplane Bus from the CTMBD in the lowest Level 1.5 Backplane slot, and passes it to the Level 1.5 Patch Panel for distribution to other Application Cards in the Level 1.5 Backplane. This cable should be made from a 9 section long piece of 64 conductor Twist'n'Flat cable. It must have 9 connectors spaced in the following relationship (lengths given in section units): the 8 lower connectors spaced 1 section apart, and the top connector spaced 2 section(s) from the next-to-top connector. The 8 lower connectors plug into the "J4" section of the Backplane for each of the 8 lower Application Cards in the Level 1.5 Backplane, and the top connector plugs into the back of the Level 1.5 Patch Panel connector labelled "CBUS." The order of the signals is inverted by passing through the Patch Panel. 3. Level 1.5 Term 0..31 DONE/ANSWER Cables 2..4 These are 3 separate cables which feed the Level 1.5 Term 0..31 multiplexed DONE/ANSWER signals from the Level 1.5 Term Fanout TLM to the Level 1.5 Term -> ST Digimem cards, and in two cases to the Level 1.5 Readout IMLRO. These cables should be made from 64 conductor Flat NO TWIST cable. One of the cables (Cable #2) must be made from a 13" piece of cable, while the other two (Cable #3 and #4) must each be made from an 11" piece of cable. Cable #2 will have 6 connectors, spaced 2_1/8" apart (as described above), while cables #3 and 4 will each have 5 connectors. Cable #2 will plug into the "J3" sections of the Backplane for each of the topmost 6 Application Cards in the Level 1.5 Framework Backplane, while Cables #3 and #4 will plug into the "J2" and "J1" sections respectively of the Backplane for each of the topmost 5 Application Cards in the Level 1.5 Framework Backplane. 4. Level 1 Specific Trigger 0..31 Fired to Level 1.5 Control DGM This cable provides the Level 1 Specific Trigger 0..31 Fired to two channels of the Level 1.5 Control DGM. It receives these signals from two of the Specific Triggers Fired Cables in the M102 Patch Panel in the Level 1 Trigger Framework. It must be made from an 8 section long piece of 64 conductor Twist'n'Flat cable. It should have 5 connectors, spaced in the following relationship: the lower 3 connectors should be 64-pin connectors spaced 1 section apart, followed by a 6 section gap which ends in a "split" cable of 2, 32-conductor sections, each of which should be terminated in a 34-pin header with pins 33 and 34 unused. The 3 lower connectors should be plugged into the "J1", "J3", and "J4" sections respectively of the Level 1.5 Control DGM slot in the Level 1.5 Framework Backplane, and the top 2 connectors will be plugged into two Specific Triggers Fired Cable outputs which will provide all 32 Specific Triggers Fired signals. It passes through the cut-out of the Level 1.5 Patch Panel. 5. Level 1 Specific Trigger 0..15 Fired to Level 1.5 IMLRO This cable provides the Level 1 Specific Trigger 0..15 Fired to one channel of the Level 1.5 IMLRO. It receives these signals from one of the Specific Triggers Fired Cable outputs on the M102 Patch Panel. It should be made from a 6 section long piece of 34 conductor Twist'n'Flat cable with 34-pin connectors on each end. One connector is plugged into one of the Specific Triggers Fired Cable outputs on the M102 Patch Panel, while the other is plugged into the lowest 16 pairs of the "J1" section of the Level 1.5 IMLRO slot in the Level 1.5 Framework Backplane. Note that 1 or 2 pairs of pins on the backplane "J1" connector will need to be removed to allow the 34-pin connector to mount to the backplane. ALSO NOTE THAT CONDUCTORS 33 AND 34 CONTAIN THE SPECIFIC TRIGGERS FIRED STROBE. It passes through the cut-out of the Level 1.5 Patch Panel. 6. Level 1 Specific Trigger 0..15 Fired to Level 1.5 Patch Panel This cable provides the Level 1 Specific Trigger 0..15 Fired to the front of the Level 1.5 Patch Panel. It receives the signals from one of the Specific Triggers Fired Cable outputs on the M102 Patch Panel, corresponding to the Specific Triggers 0..15 Fired signals.

The bottom connector is a 64-pin connector, the next-to-bottom connector is a 34-pin connector spaced 1 section away, connected only to the lowest 32 conductors of the cable. Pins 33 and 34 of this connector are unused. The next connector is a 64-pin connector spaced again 1 section away. The next connector is a 64-pin connector spaced 1 section away. Next is a 2 section gap which ends in a "split" cable of 2, 32-conductor sections, each of which should be terminated in a 34-pin header with pins 33 and 34 unused. The bottom connector plugs into the "J2" section of the Veto/Confirm MTG, the next connector plugs into the lowest 16 pairs of the "J2" section of the L1.5 Control Digimem (note that some pins need to be removed from the backplane for clearance), and the next connector plugs into the "J2" section of the Readout IMLRO. The next connector is plugged UPSIDE DOWN onto the "J2" section of the Confirm/Veto SBSC. The final 2 connectors plug into the the back of Level 1.5 Patch Panel connectors labelled "Level 1.5 Veto" and "Level 1.5 Confirm" as appropriate. The polarity of these signals is inverted by passing through the Patch Panel, so the single pair cables that are plugged into the front of the patch panel must be plugged in UPSIDE DOWN. 8. Level 1.5 Term 0..31 DONE/ANSWER from Receiving MTG to TLM This cable transports the Level 1.5 Term 0..31 multiplexed DONE/ANSWER signals from the Receiving MTG to the Fanout TLM.
