  Fig. 1 ADC channel assignment (rocfcal2, north)

• 

  Fig. 2 ADC channel assignment (rocfcal5, north)

• 

  Fig. 3 ADC channel assignment (rocfcal8, south)

• 

  Fig. 4 ADC channel assignment (rocfcal11, south)

• 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 in 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).
