Components
TS-7300 FPGA Core for TS-ENC730: Register Map
The TS-ENC730 includes a TS-7300 FPGA core designed specially for the TS-ENC730 and the TS-732 daughter companion board. This FPGA core talks to the AVR Microcontroller on the TS-732 via a UART interface, making use of the 8x baud clock reference provided by the AVR. This FPGA core also implements a SJA1000 CAN controller and 2 PWM channels for the TS-732 DAC circuitry. The registers that control these functions appear in the memory space of the ARM9 processor dedicated for the FPGA functions, therefore they can be accessed through the Linux OS and programming. The base address used is 0x7200_0400 and the register are 16-bit wide. The following is the register map for the TS-ENC730/TS-732:
| I/O Addr | Description | Data Bits and such |
|---|---|---|
| BASE + 0 | Control register | bits 3:15 - reserved bit 2: CAN controller enable bit 1: PWM channel #1 enable bit 0: PWM channel #0 enable |
| BASE + 2 | PWM channel #0 high-time | |
| BASE + 4 | PWM channel #0 low-time | |
| BASE + 6 | PWM channel #1 high-time | |
| BASE + 8 | PWM channel #1 low-time | |
| BASE + A | AVR clock reference | |
| BASE + C | AVR UART STAT register | |
| BASE + E | AVR UART RXDAT/TXDAT register | |
| BASE + 100 | CAN controller regs start | SJA1000: 256 byte x 8bit registers |
The AVR clock reference represents the current frequency/2 of the clock coming out the AVR. Nominally this should be 100Khz. Register value is updated twice per second.
Front and Rear Panels
The TS-ENC730 front panel is shown on the first page of this manual.
The rear panel of the TS-ENC730 enclosure (shown above) has all the input/output connectors, including four COM ports, one CAN port shared with another COM port, one VGA port, two ethernet ports, two USB ports and one 10-pin terminal strip. Also, it includes two LEDs, red and green.
Standard Headers and Connectors
COM1: Console RS-232 Serial Port
The COM1 RS-232 port uses a standard DB-9 male connector on the TS-ENC730.
| DB9 Pin | Signal | Description |
|---|---|---|
| 1 | DCD | Data Carrier Detect |
| 2 | RXD | Receive Data |
| 3 | TXD | Transmit Data |
| 4 | DTR | Data Terminal Ready |
| 5 | GND | Ground |
| 6 | DSR | Data Set Ready |
| 7 | RTS | Request to Send |
| 8 | CTS | Clear to Send |
| 9 | N/A | N/A |
The COM1 port on the TS-ENC730 is the default port used for system console. The RC-DB9 cable must be connected to the COM1 in order to have a Linux console via any terminal emulator.
USB
The USB Connector on the TS-ENC730 provide two USB interfaces for the user. These are directly connected to the EP9302 processor, which integrates an USB dual-port Open Host Controller Interface (Open HCI), providing full-speed serial communications ports at a baud rate of 12 Mbits/sec. Up to 127 USB devices (printer, mouse, camera, keyboard, etc.) and USB hubs can be connected to the USB host in the USB "tiered-star" topology.
ETH0 and ETH1
The ethernet connectors ETH0 and ETH1 makes use of a standard RJ-45 socket. They can be used to connect a standard 10/100 Ethernet cable into the enclosed SBC.
The ETH0 port is controlled by the ARM9 CPU, while the ETH1 port is controlled by the TS-7300 onboard FPGA.
The right side LED above the Ethernet port indicates a 100-Mbit link, while the left side LED indicates network activity.
VGA
A standard DB15 VGA connector is available on the TS-ENC730 for video interface. For further information on the VGA Video function, refer to the TS-7300 manual.
COM2/CAN
When the CAN jumpers are OFF, the COM2/CAN DB9 connector is connected straight to the COM2 header on the TS-7300, enabling communication to the second serial port on the ARM9 processor. For further information on this, please refer to the TS-7300 manual.
If the CAN jumpers are ON, then the COM2/CAN DB9 connectors brings out the CAN Bus signals. Technologic Systems provides a Linux Driver for our CAN core (Lincan Driver), which is a SJA1000. Please, refer to the TS-CAN1 manual for further information on how to use the Lincan Driver with the TS-T32/TS-ENC730.
Please notice that the CAN Bus will only work if the CAN option was ordered for the TS-ENC730 enclosure, since the CAN PHY chip is optional for this product.
The RS-232 port brought out through the COM2 DB9 connector on the TS-ENC730 corresponds to the COM2 1-pin header of the TS-7300. It is also RS-485 full/half duplex capable, if the RS-485 option was ordered.
The general pin-out for the COM2/CAN DB9 connector is shown below:
| COM2 Header | DB9 Connector | RS-232 | Half Duplex RS-485 | Full Duplex RS-485 | CAN |

The SJA1000 CAN controller on the TS-7300 FPGA run at 25Mhz, which might create problems when talking to other CAN devices clocked at standard 16Mhz or 24Mhz. Technologic Systems recommends 100Kbaud, 500Kbaud or 900Kbaud to be used with the TS-732 and the Lincan Driver. The 1042Kbaud can be used to set up a fast CAN network among TS-7300/TS-ENC730 devices only.
COM3, COM4, COM5
Standard RJ-45 sockets are used to bring out the additional COM ports, which are implemented on the TS-7300 FPGA. The RJ-45 connectors are connected straight to the FPGA COM headers (COM3, COM4, COM5) on the TS-7300. For further information on these, please refer to the TS-7300 manual.

TS-732 Jumper Settings
- The CAN_Term Jumper enables/disables a termination resistor for the CAN network
- The CL_1 to CL_4 jumpers must be ON if it is wanted the TERM1 to TERM4 to act as a current loop (0-20mA range), making the ADC lines measure actual current instead of voltage level (0-5V range)
TS-732 Internal Power Cable
The internal power cable of the TS-732 must be connected to the power input of the TS-7300 SBC in order to provide regulated 5VDC power supply to the SBC.
| WARNING: | The indicated polarity must be used when connecting this cable. |
TS-730C Routing/Connectors Board
The TS-730C board interfaces between the TS-732/TS-7300 functions and the TS-ENC730 external connectors, routing the signals to the respective connectors which are brought out on the rear panel of the enclosure.
Internal TS-730C Headers
- The 20-pin CN1 header must be connected straight to the 20-pin header on TS-732
- The 10-pin CN2 header must be connected to the 10-pin COM2 header on TS-7300
- The 10-pin CN3 header connects to the 10-pin COM3 header on TS-7300
- The 10-pin CN4 header connects to the 10-pin COM4 header on TS-7300
- The 10-pin CN5 header connects to the 10-pin COM5 header on TS-7300
TS-730C Jumper Settings
- All the CAN jumpers must be ON to have the CAN Bus enabled on the COM2/CAN DB9 connector instead of COM2
- All the CAN jumpers must be OFF to have the COM2 port enabled on the COM2/CAN DB9 connector instead of CAN
- Jumper GND6 ON makes the TERM6 of the 10-PIN Terminal Strip act as a ground in order to increase ADC accuracy by reducing IR drop effects
