Feature Description
4.1
Power Supply
Zeta base board can be powered either from any DC power supply with an output voltage range of +6V to +36V.
This range makes Zeta compatible with standard power supply voltages of 12V, 24V, and 28V. In addition, Zeta
can operate in a vehicle environment due to its ability to run on 6VDC.
Maximum allowable reflected ripple, measured at the voltage input connector is 50mV p-p.
4.2
Ethernet
Zeta base board supports one standard and one optional 10/100/1000 Ethernet port. The standard port comes
directly from the COM module. The optional port is derived from the Intel WGI210IT PCIe Ethernet controller.
This controller is accessed via x1 PCIe lane from the COM. Both ports have on-board magnetics to allow use with
a DSC standard Ethernet cable.
On-board LEDs are provided for Link, Activity, and Speed on each port. The LEDs are located along the board
edge near the Ethernet connectors. Both connectors provide access to the LED signals.
4.3
Micro SD
Zeta base board supports one micro SD connector with 4-bit data 3.3V for an additional low-cost storage option.
4.4
USB
Zeta base board supports 6 USB2.0 ports and one USB 3.0 port.
•
Four USB2.0 ports are routed to 2x5 headers for use with cables.
•
One USB2.0 port is interfaced to the PCIe Mini card socket to support USB minicards.
•
One USB2.0 port is routed to Expansion connector for use on installed daughterboards.
•
The USB 3.0 port is routed to a 2x6 pin header. This pin header is compatible with the Intel standard
dual USB 3.0 connector for convenience.
4.5
VGA
Zeta base board supports VGA display interface. DDI to VGA converter chip (CH7517) is used to covert DDI from
COM connector to VGA signals.
4.6
LCD
Zeta supports a 24-bit single channel LVDS display through a 1x20 RA latching connector. Separate backlight
supply connector provides LCD backlight supply and PWM control. Backlight supply is given externally through
the main power input connector.
4.7
Audio
HD audio from the COM is available on the expansion connector. A daughterboard is required to utilized the
audio feature.
4.8
Serial Ports
Zeta supports 4 serial ports using an LPC UART (XR28V384). UARTs from the COM are not utilized. Protocol
selection and RS-422/485 line termination are provided using an I2C digital I/O expander chip driven by the
COM. The configuration can be done in the BIOS and also via user application software.
4.9
RTC Backup Battery
