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 carrier 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.

Operating Temperature Range
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

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.
