Engineer Training RIP 3 Board (Cont. ) The Print Data is transferred from the software to the RIP through the PCI Bus. 1. The print data is transferred from the PLX PCI Bridge to the Memory Chips. 2. All the Print Data is then processed in the Altera Chips: (Master → Slave) and transferred through the SCSI 68 pin to be distributed to all four channels. 3. All the Print Support Data and Commands are processed and directed through the Altera Slave, except for the PEG data and the Encoder Signals. Confidential XL 1200 Electronics 6

Engineer Training Pumps Board The Pumps Board performs the following tasks: 1. Splits the 24 VDC to all operating Ink Cabinet channels. 2. Controls the ONOFF commands to each of the solenoids mounted on the Main Ink Cabinet. 3. Transfers the Ink Sensor reading from the Main Tanks to the RIP 2 CCB. 4. Provides LED indication of 24 V on each channel (red) and Solenoid Valve ON (green). Confidential XL 1200 Electronics 14

Engineer Training Pumps Board (Cont. ) Operation 1. The Board receives a 5 V supply from the RIP 2 CCB and 24 VDC from the power supply located under the Board. 2. The 5 V is used for the operation of the Solid State Relays. 3. The 24 V is supplied to the Valves and the Pumps. 4. The control of the Ink Valves is performed by a set of Solid State Relays.
