- Blue region corresponds to ADC channels connected to the FCAL2 insert region (21x21 lead glass modules). Yellow boxes correspond to channels connected to the region outside the insert.
- 108 ADC channels in each of four crates are connected to the insert region
- 238 ADC channels are used in each crate
Possible rearranging of cables
- Move 108 channels from the rocfcal2 (rocfcal8) crate connected to the insert to the rocfcal5 (rocfcal11) crate. The total number of channels in this crate: 108 + 108 = 216 (connect to 14 FADCs), see Fig. 1
- Move 126 channels in the rocfcal5 (rocfcal11) crate connected to the insert to the rocfcal2 (rocfcal8) crate. The total number of channels in this crate: 130 (remaining) + 126 = 256 (connect to 16 FADCs), see Fig. 2. Connect 4 remaining cables to other crates, see Fig. 3
