Hardware

fit-PC4 USB power behavior

USB ports power (5V) available in active (S0) state only, on all ports.

Power states:

  • S0 - active
  • S3 - sleep
  • S4 - hibernate
  • S5 - Shut down (SW off)

Which power supplies can power the fit-PC4?

fit-PC4 bundle comes with external AC/DC wall power supply, providing unregulated 10–15Vdc input voltage range, 12Vdc nominal, 36W output power for Value version and 60W output power for the Pro version. However, any power supply able to supply ~36W/60W from 12Vdc source will be fine.

What are power capabilities of fit-PC4 USB ports?

USB ports VBUS (5V) pair supplied via onboard power switch with current limit set to 2.1A, which means either each USB port capable sourcing up to 1.05A in case two bus powered devices are connected, or sourcing 2.1A in case single bus powered device is connected.

GPIO drive capabilities

GPIO drive strength value is configured via GPIO control registers and have 4 possible configurations: 4mA, 8mA, 12mA, 16mA

Using single RAM memory module with fit-PC4

When single SO-DIMM RAM memory module used it should populate the slot closer to an edge (P7) of the PCB, in order to pass memory initialization process.

Pigtail unterminated DC cable

Pigtail DC cable - unterminated on one end and on the other uses standard 5.5mm x 2.5mm barrel plug with mechanical twist-lock.
Can be used with IPC2, Intense PC, fit-PC4/3 and fitlet computers.

Does fit-PC4 support VMWare ESXi

ESXi is reported to work on fit-PC4, however a known issue with I211 NIC driver in ESXi software exist and addressed in few articles:

Note: The issue appeared on both ESXi 5.5 and 6.0 (VMware-VMvisor-Installer-5.5.0.update02-2068190.x86_64.iso).

Call for one-time boot selection menu

Phoenix BIOS offers one-time boot selection menu by pressing F5 during boot. To make it work user has to make sure Windows Boot Manager is not blocking its operation - it depends if OS installed in Legacy or UEFI mode.

OS in Legacy mode:
1. On computer start clicking F5 will bring you into one-time boot selection menu

OS in UEFI mode:
1. Configure Windows Boot Manager to be the last boot order option

a. Enter BIOS menu:
i. If Windows 8 or Windows 10 enter the BIOS from the OS:
1. Do steps b, c, d below
ii. If Windows 7:
1. Remove the HDD/SSD storage
2. Boot the computer without it
3. Once shell appears type exit
4. You are in the menu. Click Tab and enter Setup
5. Do steps b, c, d below
6. Install the HDD/SSD
b. Go to boot order
c. Change Windows Boot Manager to be the last in sequence
d. Save and Exit

2. On computer start Clicking F5 will bring you into one-time boot selection menu

How to enable watchdog in fit-PC4 under Linux

fit-PC4 and fitet watchdog functionality in Linux is similar:

  1. Download and install fitlet kernel package (also suitable to fit-PC4)
  2. Refer to fitlet watchdog in Linux chapter for operation instrructions
