1 Overview

The TS-8200 is a TS-SOCKET Baseboard that provides a test and development platform for Technologic Systems TS-4xxx products. and accepts any TS-4xxx Macrocontroller. The TS-8200 provides industry standard connectors for the various ports and features on many of the TS Macrocontroller products like the TS-4500, TS-4200, etc. It provides transceivers for the RS-232 ports, CAN port, and the RS-485 port, brought out to the male DB9 and .1" pitch header connections. It also has the Ethernet magnetics, RJ-45 connector, USB Host and Device connectors, Temperature Sensor, MicroSD card socket, RTC Battery (coin cell), and two LEDs. Power input requirement is regulated 5.0 to 12.0 VDC.

2 Getting Started

The TS-8200 board has no specific boot sequence since the processor and Linux Operating System are located on the selected TS-4000 Series Macrocontroller. For the rest of the boot and setup procedure, please refer to the manual for the selected TS-4000 series Macrocontroller you are using listed here.

Before attempting to apply power to the TS-8200, perform the following steps while taking proper static discharge precautions

  • Place the TS-8200 base board on a firm non-conductive surface.
  • Carefully, insert the TS-4000 Series Macrocontroller daughterboard by aligning and pressing evenly and firmly onto the pair of mating connectors
  • Connect the console serial terminal cable
  • Connect the Ethernet cable if applicable.
  • Apply power
  • Monitor the TS-SOCKET SBC using a terminal emulator connected to the serial console port to verify that the board is operating properly
  • Connect either a regulated 5.0 to 12.0 VDC on the power input connector or the regulated 5.0 VDC via USB Device port. Please note the polarity printed on the board.

See the TS-4500 page for more details on dealing with the functionality of the macrocontroller.

3 Features

3.1 Push Switch

The TS-8200 contains a push switch that has multiple functions. On unit reset (or power on) the switch connects to a simple DIO input where the state of the switch may be read. The initial startup software may branch and perform any required functionality based on the switch state. By default most TS-SOCKET products will use this switch to change the console between the Debug port and the second serial port. Please refer to the manual for the selected TS-4000 series Macrocontroller you are using listed here. The switch may also be deployed as a reset button, by setting an enable bit within the FPGA. This is the default behavior of the linuxrc on most of the TS-SOCKET products; the push button will be enabled as a reset approximately 2 seconds after a reset or power on, after it has done the change console check.

3.2 Ethernet

The TS-8200 contains a single Ethernet port interface utilizing an MMT MJKF4602 RJ-45 jack with integrated magnetics and both Link Activity and Speed LEDs. The LINK LED (right side of connector, green) is active when a valid Ethernet link is detected. This LED should be ON whenever the TS-8200 is powered and properly connected to a 10/100 BaseT Ethernet network.

3.3 MicroSD Interface

This MicroSD is on the same lines as the MicroSD on the Macrocontroller. Only one can be populated at the same time.


The JTAG header is used at the factory for programming the FPGA and CPLD. It is not available for JTAG debugging on the CPU. Using the JTAG pins to program the FPGA is not supported and not recommended.

3.5 Jumpers

Jumper Function
JTAG Enable Enables writing to the FPGA.
Write Enable Reserved
Boot SDCard Jumper on boots to SD
Jumper off boots to XNAND

3.6 Temperature Sensor

See the ts7500ctl for usage and sources for interacting with the TS-4500 temperature sensor, however this baseboard also has one that is usable through I2C.

This example shows reading the sensor:

5 Product Notes

5.1 FCC Advisory

This equipment generates, uses, and can radiate radio frequency energy and if not installed and used properly (that is, in strict accordance with the manufacturer's instructions), may cause interference to radio and television reception. It has been type tested and found to comply with the limits for a Class A digital device in accordance with the specifications in Part 15 of FCC Rules, which are designed to provide reasonable protection against such interference when operated in a commercial environment. Operation of this equipment in a residential area is likely to cause interference, in which case the owner will be required to correct the interference at his own expense.

If this equipment does cause interference, which can be determined by turning the unit on and off, the user is encouraged to try the following measures to correct the interference:

Reorient the receiving antenna. Relocate the unit with respect to the receiver. Plug the unit into a different outlet so that the unit and receiver are on different branch circuits. Ensure that mounting screws and connector attachment screws are tightly secured. Ensure that good quality, shielded, and grounded cables are used for all data communications. If necessary, the user should consult the dealer or an experienced radio/television technician for additional suggestions. The following booklets prepared by the Federal Communications Commission (FCC) may also prove helpful:

How to Identify and Resolve Radio-TV Interference Problems (Stock No. 004-000-000345-4) Interface Handbook (Stock No. 004-000-004505-7) These booklets may be purchased from the Superintendent of Documents, U.S. Government Printing Office, Washington, DC 20402.
