1 Overview

The TS-752 demonstrates the flexibility of a Technologic Systems SoM by connecting FPGA driven IO pins to relays, buffered digital inputs, buffered digital outputs, and RS-485 drivers. It also provides an RS-232 driver for the serial console. A TS-ENC750 with a TS-7500 or TS-7550 can provide a complete solution for many embedded applications.

2 Getting Started

The TS-752 is powered using the P8 connector (8 pin terminal block) shown here. For more details about standard functionality on this board, see your ARM board page. Console is available from the DB9 connector as RS232 at 115200 baud, 8n1, and with no flow control.

3 Features

3.1 Host-board Recovery

Although it is easy to get a TS-7500 board into an unbootable state during development if you botch a modification, it is equally easy to use the TS-752 to recover the default startup. To do so, place the JP2 jumper on the TS-752 and reset the board. In approximately 3 seconds, the board will have fastbooted to the TS-752 flash and present a shell prompt. To recover the default initrd and linuxrc, enter the command "spisave", remove the JP2 jumper, and reboot back to a restored to factory default configuration. The procedure is identical on the TS-7550 except you use the "nandsave" command since the TS-7550 has no SPI flash onboard.

3.2 Relays

The TS-752 features 3 SPDT relays rated for 5A at 277VAC or 30VDC that the user can toggle through DIO. You can drive these DIO high or low to toggle the relays, or use the ts.subr file which lets you set a 3 bit value to control the relays.

The PCH-105D2H relay is normally open, closes in 10ms, and opens in 5ms. A very safe assumption would be that it will switch after 20ms.
