The TS-TPC-8390 is a complete touch panel computer solution comprised of a 7" TFT LCD, TS-8390 baseboard and a choice of System-on-Module (SoM) CPUs. It is an ideal solution for applications requiring a touch screen human machine interface (HMI), such as industrial automation, home automation, self-service machines, and point-of-sale terminals. This product offers an excellent value with a full range of features and industry standard connectors and a fanless, low power, high performance modular design. TS-TPC-8390 also provides an upgrade path for embeddedTS' customers currently using TS-TPC-7390 and TS-TPC-7395 products.
TS-4800
See the TS-4800 page for functionality regarding the CPU, FPGA, and OS.
The TS-8390 board has no specific boot sequence since the processor and Linux Operating System are located on the selected TS-4000 Series System-on-Module (SoM). For the rest of the boot and setup procedure, please refer to the manual for the selected TS-4000 series SoM you are using.
Before attempting to apply power to the TS-8390, perform the following steps while taking proper static discharge precautions
Place the TS-8390 base board on a firm non-conductive surface.
Alternatively on the provided stand.
Carefully, insert the TS-4000 Series SoM by aligning and pressing evenly and firmly onto the pair of mating connectors.
If ordered together these will already come preassembled.
Connect the RC-DB9 to the 10 pin COM1 header lining up the red wire to the white dot on the board.
Connect the Ethernet cable if applicable.
Make sure the jumper is on the "Console Enable" pins, and connect the "SD Boot" pins for the full X11 interface.
Apply 5-28V of power to the two power pins. Please note the polarity printed on the board.
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-4800 page for more details on dealing with the functionality of the SoM.
Features
Touch Screen
The touch screen on the TS-TPC-8390 is comprised of a two channel ADC and a portion of the TS-4800's FPGA. The touch controller's raw data can be accessed for a number of custom applications, including the collection of custom calibration data and polling for specific touch instances. This data is presented with two registers on the TS-4800:
This ADC functionality can be accessed on the TS-4800 by using the TS-4800#ADC Core.
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.
The TS-TPC-8390's secondary Ethernet port (labelled ETH2 on the silkscreen) generally shows up to linux identified as eth1. This identification can change depending on local conditions, such as the use of one microSD card to test multiple devices. To access this device, simply use ifconfig -a to list all interfaces and find what the secondary is identified as, then 'ifconfig eth1 up' (for example) to prepare the secondary Ethernet device for configuration.
Product Notes
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.
