Introduction
Overview
The Relio R2 SYNC is an exceptionally rugged embedded controller with integrated synchronous communications ports for operating in harsh environments. The R2 SYNC’s fan less and cableless structure ensures extensive durability for long-term usage. The R2 SYNC differs from traditional industrial computer systems in that it is built using the PICMG COM Express architecture . Sealevel has partnered with the leading
COM Express module manufacturers to ensure our customers benefit from the best in the industry. This manual will focus on the higher-level features of the R2 SYNC computer system.
The R2 SYNC is compatible with Basic and Compact form factor Type 6 pin out COM Express modules. COM
Express is a widely supported implementation of Computer on Module (COM) design. The COM Express architecture reduces the complexity, cost and time required for custom computer system design by combining the processing, memory, video, Ethernet, and USB functionality in a small, highly integrated module. COM
Express modules install on a carrier board that provides the application specific I/O and external connectors best suited for the system requirements.
Sealevel COM Express carr ier boards leverage the company’s years as a leader in I/O and communication products to provide carrier board and full system solutions in the fastest time possible. Common I/O features include serial, analog and digital I/O. Sealevel’s extensive library of proven I/O circuits can be included as required to meet the specific I/O count, voltage ranges, and connector types.
The R2 SYNC is equipped with a four-port RS-232, RS-422, RS-485,EIA-530, EIA-530A, V.35 synchronous serial interface. Designed using the popular Zilog Z85230 Enhanced Serial Communication Controller (ESCC), the board is an ideal solution for military, satellite, radar, banking, and other applications that require robust synchronous communications.
For maximum flexibility, each of the serial ports can be individually configured for RS-232, RS-422, RS-485,EIA-
530, EIA-530A, V.35 communications. In RS-232 mode, all common modem control signals are implemented for compatibility with a wide range of peripherals. A digital phase lock loop (DPLL) is included on each port, and the board supports data rates up to 128K bps in burst mode. For easy implementation, a fan-out cable is included that terminates the onboard 100-pin connector to four DB-25M connectors.
Software support, critical for successful synchronous communication development, is provided through
Sealevel’s SeaMAC driver. HDLC/SDLC protocols are supported as well as certain configurations of Monosync,
Bi-sync, and Raw modes.
The R2 SYNC also utilizes the Exar SP-506 multi-protocol electrical interface chip that allows it to be compliant with EIA/TIA-530/530A, EIA/TIA-232E, EIA/TIA 485, and ITU V.35. Optional cables are available to connect RS-
449, RS-530, RS-530A, V.35 and X.21 interfaces.

R27008-01 IBR-i7-3517UE 0 - 50 °C Requires Industrial Temperature SSD
The R2 SYNC7008 can operate with no airflow at 50C as long as the steady-state CPU usage does not exceed
50%. If CPU usage is sustained at a workload greater than 50%, the CPU will throttle itself back to keep its internal temperature in a safe range.
If the application environment requires the computer to operate at 50C with steady state CPU usage greater than 50%, some additional cooling must be used to ensure safe operation of the electronics.
The R2 SYNC computer system is a fan-less, solid state computer that relies on thermal conduction to move heat from internal components to the outside of the enclosure. The lid is designed as a finned heat sink to increase overall surface area. Three main cooling methods can be used to optimize removal of heat from the system.
1.
Airflow
2.
Thermal conduction through mounting
3.
Computer orientation
1 Width listed is for computer without mounting brackets. Total width with brackets is shown in drawings.
2 Operating temperature is dependent on particular model. See the Operating Temperature Range section for model
capabilities.

SPECIFICATIONS, CONTINUED
Airflow over the lid provides the most effective heat removal of these three options. It is optimal to mount the computer in an area that has either natural or forced airflow to constantly remove heat from the enclosure.
Mounting the computer to a large thermally conductive surface (such as an I-Beam, steel cabinet or other large metal surface) allows heat to travel through the enclosure and be dissipated into the large structure.
Power Supply
The power supply provided has a universal AC input. It provides 21 VDC @ 3.0 A max output to the R2 SYNC system. Typical power consumption varies depending on COM Express Module, memory capacity,
OS/software activity and peripheral devices. AC current draw will never exceed 1.4 A.
All necessary system voltages are generated from a single DC input capable of accepting 18 VDC to 36 VDC
(fed by above DC power supply).
Acceptable System Input Voltage 18 VDC-36 VDC
DC Current Rating (Dependent on COM Express
Module , input voltage and load)
375 mA-2150 mA
Power Input
The 12003 carrier board is designed to operate from 18VDC up to 36VDC. The current draw varies across this range and is heavily dependent on the COM Express module, peripheral devices, and installed software. The connector at J9 is Kycon KPJX-4S. Use Kycon KPPX-4P as the mate if creating your own power cable.

System Operation
Power Button
The power button on the front of the computer can be used to turn the system on, shut the system down or place the computer in sleep states S3 or S4 (depending on OS support and configuration). The power button can also wake the system up from sleep states S3 or S4.
The power button has a 3 second hardware debounce/delay built in so accidental shutdown does not occur.
This 3 second delay is present at all times so the power button must be held for 3 seconds before system power up, power down, sleep or wake occurs.
Power States
The R2 SYNC is designed to operate in four Power States as defined by ACPI.
S0 – Fully powered and operational
S3 – Suspended to memory (known as sleep in Windows)
S4 – Suspended to disk (known as Hibernate in Windows)
S5 – Powered down in standby (Windows Shutdown)
The system can transition from S0 to any of the three listed standby states (S3, S4, or S5) by either software command or the Power Button. The system can then be awoken from either listed sleep/standby state by holding the Power Button for 3 seconds. The system can also be awoken from S3 or S4 with a USB input device such as a HID compliant keyboard or mouse.
To be awoken from a standby state with a USB device, the device must be present when the computer enters the sleep state and must remain connected for the duration of the sleep state.
These power states are supported by Windows 8, Windows 7, Windows Vista, and Windows XP.
Synchronous Serial Communication Ports
The R2 SYNC utilizes the Zilog Z85230 Enhanced Serial Communications Controller (ESCC) and includes a dedicated Z85230 per port. This chip features programmable baud rate, data format and interrupt control.
Refer to the ESCC User Manual, available from Zilog, for details on programming the 85230 ESCC chip in the event you are writing your own driver as opposed to using the SeaMAC driver.
Internal Baud Rate Generator
The baud rate of the ESCC is programmed under software control. The standard oscillator supplied with the board is 7.3728 MHz. However, other oscillator values can be substituted to achieve different baud rates. It should be noted that the Z85230 chip is manufactured in different speed ranges and installation of a different oscillator may also require changing the Z85230.

BIOS Considerations
The BIOS functions, features, and settings are fully contained on the COM Express module. Refer to the COM
Express module manufacturer’s website for detailed BIOS settings. A few settings are generally present among
COM Express Modules that can affect functionality.
• COM Express Type 6 modules have DDIs (Digital Display Interfaces) that can be implemented as
DisplayPort, HDMI, or DVI interfaces. The R2 SYNC carrier board implements DisplayPort only. Ensure DDI1 is set to DisplayPort interface in the BIOS.
Some Passive DisplayPort to DVI adapters have been found which require DDI1 to be set to HDMI/DVI with the R2 SYNC1004 BIOS. This is the exception, not normal behavior.
1.
Attach a USB keyboard to the computer.
2.
Apply power and immediately press the delete key, repeatedly for 15 seconds. This will ensure the computer has had time to boot and enter the BIOS.
3.
Press the F9 key to load optimal defaults then press enter to validate the change.
4.
Press the following key pattern:
• Right arrow,
• Enter
• Down arrow 9 times
• Enter
• Up arrow
• Enter
• F10
• Enter
5.
If performed properly, the DDI1 setting will have been restored to DisplayPort, the BIOS settings were saved to flash memory and the computer was rebooted. The display should now be working.
If this does not work, contact Sealevel Systems Technical support.
6.
Once the computer has rebooted and video is working, it is a good idea to disable the LVDS flat panel interface. It was enabled by restoring “Optimal Defaults”
7.
Enter the BIOS, go to the Graphics section, and change the “Active LFP” setting to “No LVDS”
8.
Change the “Power Loss Control” setting to “Turn On” (or the setting that is appropriate for your application environment).
9.
Press F10 to save settings and exit.
“ Power on after PWR Failure” is a setting present in most BIOS. This setting determines if t he computer boots when power is applied. R2 SYNC computers are shipped with this set to always power on however “Remain Off” and “Last State” are valid settings.

Handling Instructions
ESD Warnings
Electrostatic Discharges (ESD)
• A sudden electrostatic discharge can destroy sensitive components. Proper packaging and grounding rules must therefore be observed. Always take the following precautions:
Transport boards and cards in electrostatically secure containers or bags.
• Keep electrostatically sensitive components in their containers, until they arrive at an electrostatically protected workplace.
• Only touch electrostatically sensitive components when you are properly grounded.
• Store electrostatically sensitive components in protective packaging or on anti-static mats.
Grounding Methods
The following measures help to avoid electrostatic damages to the device:
• Cover workstations with approved antistatic material. Always wear a wrist strap connected to a properly grounded workplace.
• Use antistatic mats, heel straps, and/or air ionizers for more protection.
• Always handle electrostatically sensitive components by their edge or by their casing.
• Avoid contact with pins, leads, or circuitry.
• Turn off power and input signals before inserting and removing connectors or connecting test equipment.
• Keep work area free of non-conductive materials such as ordinary plastic assembly aids and
Styrofoam.
• Use field service tools such as cutters, screwdrivers, and vacuum cleaners that are conductive.

Electrical Interface
RS-232
Quite possibly the most widely used communication standard is RS-232. This implementation has been defined and revised several times and is often referred to as RS-232 or EIA/TIA-232. The IBM PC computer defined the RS-232 port on a 9-pin D-sub connector, and subsequently, the EIA/TIA approved this implementation as the EIA/TIA-574 standard. This standard is defined as the 9-Position Non-Synchronous
Interface between Data Terminal Equipment and Data Circuit-Terminating Equipment Employing Serial Binary
Data Interchange. Both implementations are in widespread use and will be referred to as RS-232 in this document. RS-232 is capable of operating at data rates up to 20K bps at distances less than 50 ft. The absolute maximum data rate may vary due to line conditions and cable lengths. RS-232 is a single-ended or unbalanced interface, meaning that a single electrical signal is compared to a common signal (ground) to determine binary logic states. The RS-232 and the EIA/TIA-574 specification define two types of interface circuits: Data Terminal
Equipment (DTE) and Data Circuit-Terminating Equipment (DCE).
RS-485
RS-485 is backwardly compatible with RS-422; however, it is optimized for party line or multi-drop applications.
The output of the RS-485 driver is capable of being Active (enabled) or Tri-State (disabled). This capability allows multiple ports to be connected in a multi-drop bus and selectively polled. RS-485 allows cable lengths up to 4000 feet and data rates up to 10 Megabits per second. The signal levels for RS-485 are the same as those defined by RS-422. RS-485 has electrical characteristics that allow for 32 drivers and 32 receivers to be connected to one line. This interface is ideal for multi-drop or network environments. RS-485 tri-state driver
(not dual-state) will allow the electrical presence of the driver to be removed from the line. Only one driver may be active at a time and the other driver(s) must be tri-stated. RS-485 can be cabled in two ways, two wire and four wire mode. Two wire mode does not allow for full duplex communication and requires that data be transferred in only one direction at a time. For half-duplex operation, the two transmit pins should be connected to the two receive pins (Tx+ to Rx+ and Tx- to Rx-). Four wire mode allows full duplex data transfers. RS-485 does not define a connector pin-out or a set of modem control signals. RS-485 does not define a physical connector.

Asynchronous Communications
Serial data communications implies that individual bits of a character are transmitted consecutively to a receiver that assembles the bits back into a character. Data rate, error checking, handshaking, and character framing (start/stop bits) are pre-defined and must correspond at both the transmitting and receiving ends.
Asynchronous communications are the standard means of serial data communication for PC compatible and
PS/2 computers. The original PC was equipped with a communication or COM port that was designed around an 8250 Universal Asynchronous Receiver Transmitter (UART). This device allows asynchronous serial data to be transferred through a simple and straightforward programming interface. A starting bit followed by a predefined number of data bits (5, 6, 7, or 8) defines character boundaries for asynchronous communications.
The end of the character is defined by the transmission of a pre-defined number of stop bits (usually 1, 1.5, or
2). An extra bit used for error detection is often appended before the stop bits. The diagram below demonstrates asynchronous communication bits.
Asynchronous Communications Bit Diagram
This special bit is called the parity bit. Parity is a simple method of determining if a data bit has been lost or corrupted during transmission. There are several methods for implementing a parity check to guard against data corruption. Common methods are called (E)ven Parity or (O)dd Parity. Sometimes parity is not used to detect errors on the data stream. This is referred to as (N)o parity. Because each bit in asynchronous communications is sent consecutively, it is easy to generalize asynchronous communications by stating that each character is wrapped (framed) by pre-defined bits to mark the beginning and end of the serial transmission of the character. The data rate and communication parameters for asynchronous communications have to be the same at both the transmitting and receiving ends. The communication parameters are baud rate, parity, number of data bits per character, and stop bits (i.e., 9600,N,8,1).
