The Cassini Tester uses a System Controller to operate; these procedures describe how to upgrade a rev-A,B,C RI8568 Cassini 16 Infrastructure to use the new Linux NUC and how to downgrade the use the ArcaOS EPC.
To Upgrade RI8574 ArcaOS EPC TIM and Connect RI8613A USB RIFL Master TIM and RI8608 Linux NUC:
- Follow the steps to power off the EPC. (ArcaOS > Shut Down... > Power Off)
- On the Cassini 16 Infrastructure, rotate the Power Switch to the OFF position.
- Unlatch the RI8574 EPC TIM from the Cassini 16 Infrastructure (T0 Location) and remove the TIM. (see Figure 2)
- Attach the RI8613A USB RIFL Remote TIM to T0 Location and latch the TIM. Be sure the latch is fully closed.
- Place the RI8608 Linux NUC on a workspace (desk) or attach to a VESA Mount on the Display or Cassini Infrastructure (P/N N0T9464A). (See Figure 4)
- Connect the Power Supply to the wall receptacle and to the Linux NUC DC-In port.
- Attach the USB cable between the RI8613A USB RIFL Master (see Figure 3) and the RI8608 Linux NUC. Connect the Keyboard/Mouse, Network and Display.
- Power ON the Linux NUC by pressing the power button. (See Figure 4)
- On the Cassini 16 Infrastructure, rotate the Power Switch to the ON position to activate the RI8613A USB RIFL Remote TIM.
- Follow the Exchange Linux NUC Checklist ( https://roos.com/docs/RBEH-DG2R6U ) to set Network Address, Host name, Timezone and other common configuration options. Be prepared to provide the MAC Address (LAN) id (##-##-##-##-##) found on the bottom label of the NUC (See Figure 5). Use the Network Manager UI from the task bar to configure for your corporate LAN and startup the Tester (see Figure 6 and 7).
To Downgrade, Remove RI8613 USB RIFL Master TIM and Connect RI8574 ArcaOS EPC TIM:
The following procedure will downgrade the system controller. Please contact [email protected] and describe any issues with the RI8608 Linux NUC.
- Follow the steps to power off the System Controller. (OS > Logout > Shut Down...)
- On the Cassini 16 Infrastructure, rotate the Power Switch to the OFF position.
- Disconnect the USB cable from the RI8613A USB RIFL Remote TIM. (It is OK to leave the Linux EPC running.)
- Unlatch the RI8613A USB RIFL Remote TIM from the Cassini 16 Infrastructure (T0 Location) and remove the TIM.
- Attach the RI8574 ArcaOS EPC TIM to T0 Location and latch the TIM. Be sure the latch is fully closed.
- Connect the VGA Display cable, Ethernet Network and Keyboard/Mouse.
- On the Cassini 16 Infrastructure, rotate the Power Switch to the ON position to activate the EPC and follow the steps to startup the Tester.
- (Optional) Follow the Exchange RI8574 ArcaOS EPC TIM Checklist https://roos.com/docs/RBEH-APL2LM to set Network Address, Host name, Timezone and other common configuration options.
Hardware Compatibility:
The Linux NUC does NOT include display cable(s), network cables or USB Keyboard/Mouse. An HDMI, USB-C to USB-C (Thunderbolt), or USB-C to Displayport cable may be required to connect to the Display. The old VGA cable is not compatible with the Linux NUC. Some RI8574 ArcaOS EPC TIMs included a PS/2 Keyboard and mouse that are not physically compatible with the Linux NUC without a PS/2 to USB adapter.
Software Compatibility:
The RI8608 Linux NUC runs Linux "xUbuntu 24.04 LTS" (or later) and includes Guru Saturn application to operate the Cassini system. The Cassini application is also available running in a virtual ArcaOS container and is referred to as "Cassini in Container".
With a Guru connection (system button is green), then all Guru apps will automatically get the latest version and no migration is needed. For example, if calibrating the Tester with the Linux NUC, then switching to the ArcaOS EPC, the software will automatically use the latest Cal Data available in Guru.
Requirements:
The RI8608 Linux NUC requires a USB RIFL Master provided by the RI8613A USB RIFL Master TIM when using RI8568(A-B-C) Cassini 16 Infrastructure model. The rev-D Cassini16 Infrastructure includes native USB RIFL Master built-in to the Infrastructure and is not compatible with the RI8574 ArcaOS EPC TIM. The RI8608 Linux NUC replaces the "computer" in the RI8574A EPC TIM. The RI8613A contains the 10 MHz reference clock and physical RIFL adapter needed to control the tester via USB cable. A USB cable to connect with the Linux NUC is included with RI8613A or RI8568D.
A network connection is required before Guru and Saturn is launched automatically. Wait for the "Tester Loaded" message in Saturn's message window before launching the Cassini application from the Short Cuts menu.

To Setup a Static IP Address:
The Linux NUC will be pre-configured to get a network configuration using DHCP. Most corporate LANs prefer assigning Static IP address to Testers. To proceed, get the assigned IP Address (##.##.##.##), Netmask (##), Default Route (##.##.##.##). and DNS Server(s) (##.##.##.##), provided by your network administrator. The Hardware Address (MAC) is visible from the Connection Information display or the serial lable on the bottom of the Linux NUC device. Access the Network Manager > Edit Connections... (See Figure 1) window to create or edit the configured ethernet settings (See Figure 2). The Roos Guru auto-start script waits for a network connection before launching the software and will not work offline. Refer to the RI8608 Linux NUC Admin Guide https://roos.com/docs/RBEH-DFTNQE for more configuration options.
Subnet Mask or Netmask is in "CDIR" notation
