1 Overview

The TS-8160 is a TS-SOCKET baseboard that provides an upgrade path for Technologic Systems TS-7260 and TS-7800 products. This board accepts any TS-4xxx macrocontroller. It interfaces to the macrocontroller via two TS-SOCKET standard 100-pin connectors and brings out the various ports to industry standard connectors. The TS-8160 is compatible with the TS-ENC720 enclosure.

1.1 TS-4500

See the TS-4500 page for functionality regarding the CPU, FPGA, and OS.

TS-4500 Cavium CNS2132 250MHz ARM9

2 Getting Started

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

  • Place the TS-8160 base board on a firm non-conductive surface.
  • Place the COM1 "Console Enable" jumper in the console position so the debug port is brought out to the DB9 and COM1 headers.
  • Carefully, insert the 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 is 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

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

3 Features

3.2 DIO header

The DIO is manipulated through tsctl, or through manipulation of the registers directly.

Using tsctl will be the easiest way to communicate with the IO. This example will show the simplest way to toggle the IO, but see the tsctl page for more advanced usage.

# The easiest approach is to invoke tsctl directly.
# Do not do this if the tsctl server is already running.
# Toggle the DIO high and low directly as follows:
tsctl DIO SetAsync 8160_DIO_1 high
tsctl DIO SetAsync 8160_DIO_1 low

# If you want to share the tsctl functionality
# among multiple processes or access it via TCP/IP,
# you will need to run the tsctl server and access it as a client:
tsctl --server

# Once the server is started it will daemonize and you can access it over TCP/IP.
# Toggle the DIO high and low via the tsctl client:
tsctl @ DIO SetAsync 8160_DIO_1 high
tsctl @ DIO SetAsync 8160_DIO_1 low

# Note that the '@' is optional if the host name is an IP address of form X.X.X.X
# For consistency we recommend always including the '@'

# Note in the above example, the values 8160_DIO_1, high and low are automatically 
# looked up to produce integer values. You can also do this manually, as show below:

# Lookup the logical DIO mapping of the dio header pin 1
eval `tsctl System MapLookup 8160_DIO_1`
# If you run this outside of the eval it will return:
# System_MapLookup_0=XXX
# where XXX is the actual logical DIO number. 
# If you look up "high" it will return 1, while "low" will return 0
# note that lookups are case-insensitive

# Toggle the DIO high and low:
tsctl @ DIO SetAsync $System_MapLookup_0 high
tsctl @ DIO SetAsync $System_MapLookup_0 low

Power to the LCD header can be toggled by manipulating LCD Enable in the #Register Map. The LCD_5V pin can provide up to 1400mA, but this is a shared 5V rail and will depend on your power supply and what other devices are using that rail.

3.4 ADC Header

The Analog to Digital Converter consists of a 4-channel 16 bit sigma-delta converter and two, 2-channel analog switches. These are configured to allow input and conversion on two differential channels and 4 single ended channels. The 6-channel Analog to Digital signals are contained on connector HD5 which is a 16 pin (2x8) 0.1" spacing header. The connector layout and the signals carried by each pin are defined below. The input range for the differential input channels is 0- 2 VDC, and the input range on the single-ended channel is nominally 0-10 VDC.

3.5 CAN

CAN_H is on DB9 pin 4 and COM1 header pin 4

CAN_L is on DB9 pin 9 and COM1 header pin 9

You can find usage of the CAN port here.

3.6 Sleep mode

The TS-8160 features a AVR that has the ability to cut power to the macrocontroller for a specified amount of time. You can also use the jumper labelled 'WAKE', or the press the button on SW1 to restore power to the macrocontroller.

The ts8160ctl is available here.

Sleeping the board is essentially a shutdown. It is recommended that you have all of your filesystems in a read only state before running this command to avoid disk corruption. This example will simply shut down the macrocontroller for 20 seconds.

ts8160ctl --sleep 20

Power consumption during sleep mode is approximately 100uA.

Note: Sleep times will be rounded up to the granularity of sleep, which is 8 seconds for sleeps under ~3 days and 2048 seconds for longer sleeps. Actual sleep time will be +/- 10% the requested time due to low-power oscillator variation.

3.7 COM ports

Port Type RX (or 485 +) TX (or 485 -) Notes
ttyS0 RS232 DB9 pin 2, COM1 header pin 2 DB9 pin 3, COM1 header pin 3 Only with console enable jumper on
ttyS1 (XUART 0) RS485 DB9 pin 1, COM1 header pin 1 DB9 pin 6, COM1 header pin 6 Optional RS422 RX COM2 header pins 4(+) and 9(-)
ttyS2 RS232 DB9 pin 2, COM1 header pin 2 DB9 pin 3, COM1 header pin 3 Only with console enable jumper off
ttyS3 RS232 DB9 pin 8, COM1 header pin 8 DB9 pin 7, COM1 header pin 7
ttyS4 RS232 COM2 header pin 2 COM2 header pin 3
ttyS5 RS485 COM2 header pin 1 COM2 header pin 6
ttyS6 RS232 COM3 header pin 2 COM3 header pin 3 CTS available on pin 8

The COM headers follow a legacy pin configuration different from other pin header numberings. The COM headers are numbered thus:

1 6
2 7
3 8
4 9
5 10

Pin 1 corresponds to the pin next to the "dot" on the silk screen.

3.8 PC104 Header

See the TS-4500#PC104 section for more details on working with the PC104 bus.

The PC-104 connector consists of two rows of pins labeled A and B, the numbering of of which is shown below. The signals for the PC-104 are generated by the MAX240 PLD located on the baseboard. It converts the MUXBUS signals from the dual 100-pin Macrocontroller interface bus. Pin A1 is nearest to the macrocontroller mounting hole.

Any of the IO on this board labelled DIO_ can be controlled through tsctl as PC104_A/B<pin>, or through manipulation of the registers directly.

# Start tsctl server if it is not already running.
# This only needs to be done once
tsctl --server &

# Lookup the logical DIO mapping of the PC104 header pin A16
eval `tsctl System MapLookup PC104_A16`
# If you run this outside of the eval it will return:
# PC104_A16=138

# Toggle the DIO high and low:
tsctl DIO Set $PC104_A16 high
tsctl DIO Set $PC104_A16 low

You can also drive these DIO to manually manipulate the PC104 address to make peripherals usable that require a higher range of address than provided by the default address space of the MUXBUS.

WARNING: Most of the pins on the PC104 bus are only 3.3V tolerant. Refer to the schematic for more details.

4 Register Map

All of these registers are intended for 16 bit access. On the TS-4500 this is accessed through a memory window that is not included in the default bitstream. See this page for more details. The SBUS examples include functions for accessing this general purpose memory window.

First set the MUXBUS configuration register so you can communicate with offboard devices.

ts7500ctl --address 0x20000 --poke16 0x181

After that you can use a simple C application to talk to these addresses:

#include <stdio.h>
#include "sbus.h"

int main()
     short boardid;
     boardid = winpeek16(0x0);
     printf("Board ID: %04X\n", boardid);

     return 0;

5 Errata

5.1 TS-8160 AVR will not wake from sleep with button

Synopsis Rev 2 of the AVR software does not correctly use the WAKE button/pins
Severity Minor
Class Software bug
Affected TS-8160 AVR Rev 2
Status Workarounds available, fixed in Rev 3, shipping on June 12th 2012


Revision 2 of the AVR software did not correctly enable the interrupt for the IO port that the WAKE button/pins are on. Because of this sleep could not be interrupted without cutting power to the TS-8160. The only way to fix this is by updating to Rev 3. There are two ways to do this, see below for more information.

Workaround: The TS-8160 AVR software revision can be checked with:

ts8160ctl --info

If the Revision field shows "2" then this device cannot wake up from a sleep. The fix is as follows:

1) The Macrocontroller NEEDS to be a TS-4200. Currently none of our other Macrocontrollers can reprogram the AVR. If this is the case, an RMA can be submitted and we will reflash the AVR here. Submit an RMA request here.

2) Download this tarball, unzip it in the fastboot shell on the TS-4200 while booted with the TS-8160. Follow the instructions contained in the README file. Once this is completed, reboot, and the new AVR software will be running.

Due to space limitations, it is best to download and unpack in the /tmp folder of the fastboot shell
