Appendix A shows the available assemblies and development kits.

Appendix B lists the MultiTech SocketModems TM compatible with the JANUS-MM board.

Functional Overview

The board provides a standard PC/104 bus interface and dual CAN ports for interfacing to a CAN network. The dual

CAN ports are opto-isolated, providing channel-to-channel and channel-to-system isolation.

Optional interfaces also support integration of a Trimble Navigation GPS and a wireless MultiTech

SocketModem

TM

. The GPS and wireless modem interface to the system through an Exar 16C2850 dual UART. An external TTL-level modem port is also available when the SocketModem TM is not being used.

Figure 1 shows the JANUS-MM functional block diagram.


The board is designed for applications that can involve wireless communications and use positional information, obtained from a GPS receiver, to control devices connected on a CAN bus.

The UART is a dual port device that connects serial port 1 to a GPS receiver and serial port 2 to either a second GPS receiver or a SocketModem

TM

depending on the application. Refer to Appendix A for a list of configuration options.

A dual 16C2850 UART provides for the various configurations options. UART port 1 connects to one of the two

GPS receiver serial ports and port 2 connects to either the second GPS serial port or to a SocketModem TM .

Jumpers are provided to configure board functionality, including IRQ selection.

The CAN bus interface, supporting CAN Specification 2.0 using the Philips SJA1000 CAN controller, implements the full CAN bus protocol.

The PC/104 bus connects to other stacked PC/104-standard components in the system, providing for CPU control of the board.

CAN IRQ Selection

Use jumper J5 to specify the IRQ for both CAN ports. The following diagram shows the jumper pin layout.

(The default jumper settings shown in the diagram apply to the CAN+UART and CAN-only configuration options).

Figure 13: J5 Jumper with Default Settings

The pin label corresponds to the IRQ (IRQ3-IRQ7, IRQ9-IRQ12, IRQ14, IRQ15).

The center column of pins corresponds to the IRQ. Assign the IRQ to CAN port A (CAN A) by shorting the center pin and the pin to its left. Similarly, assign the IRQ to CAN port B (CAN B) by shorting the center pin and the pin to its right. In the diagram, above,

IRQ5 is assigned to both CAN ports and pulled down.

To share the same IRQ on both CAN ports A and B, short the pin labeled ‘S’ to its corresponding center pin, and jumper the desired IRQ for either CAN ports A or B. Refer to for an example of the use of the ‘S’ pin.

To associate the pull-down resistor on this board with the IRQ for the CAN port, short the ‘R’ pin of the CAN port and the center pin.

Note: Only one pull-down resistor is allowed per IRQ in the entire PC/104 stack.

CAN Termination, Slew Rate and Power Supply Selection

Jumpers J10 and J11 provide CAN termination, slew rate and power supply selection for both CAN ports; J10 is used to configure CAN port A and J11 is used to configure CAN port B. The following diagram shows the jumper pin layout.

(The default jumper settings shown in the diagram apply to the CAN+UART and CAN-only configuration options).

(default)

CAN Termination

Shorting the CAN termination jumper (T) puts a 120-Ohm resistor between CANL and CANH.

Note: The CAN bus should be terminated only at the ends of the bus, for a maximum of two terminations on the bus.

CAN Slew Rate

For high-speed operation, the transmitter output transistors are switched on and off as fast as possible. In this mode, the rise and fall slope is not limited. Use of a shielded cable is recommended to avoid RFI problems. The slope

control operating mode allows the use of an unshielded twisted pair or a parallel pair of wires as bus lines by programming the rise and fall slope with a resistor connected to ground.

Short the slew rate jumper (SR) to select high-speed operating mode.

CAN Power Supply Selection

Because the CAN ports and transceivers are isolated, it is possible that two different ports will not communicate properly if the voltage differential is too great. The J10/J11 jumpers (CG, CP, LP) are provided to attach/remove these power rails. One way to ensure that the two ends of the CAN communication are within voltage range is to share the same ground, or use one power supply for both terminals. Also, the local supply may be used to power the bus, and the local port may be powered from the bus.

The following options are provided to attach/remove the power rails.

•

Power from the local isolated power supply (DCP).


•

•

Power from a remote power supply, over the CAN bus.

Power from the local power supply which is also used to power remote ports.

The following figure shows the jumper settings for the power supply options.

Figure 15: Power Supply Selection Example

UART Configuration

The UART is a dual port device that connects to GPS serial port 1 and to either GPS serial port 2 or the

SocketModem TM , depending on the application.

This section presents the following UART configuration topics.

Function and power selection

UART Base address selection

The base address uniquely assigns the UART address within the PC/104 system. Use pin sets CM0, CM1 and CM2 of jumper J4 to set the UART base address.

Note: The pin layout shows the default factory jumper settings for the dual UART memory configuration options. (The IO/M jumper only applies to CAN memory addressing).

UART IRQ Selection

The UART can be configured to generate interrupts using a particular IRQ with the PC/104 system.

Use jumper J6 to select the IRQ for both UARTs. The following diagram shows the jumper pin layout.

Note: The default jumper settings shown in the diagram apply to the CAN+UART and UART-only configuration options.


The pin label corresponds to the selectable IRQ (IRQ3-IRQ7, IRQ9-IRQ12, IRQ14, IRQ15).

The center column of pins corresponds to the IRQ. Assign the IRQ to UART A (COM A) by shorting the center pin and the pin to its left. Similarly, assign the IRQ to UART port B (COM B) by shorting the center pin and the pin to its right. In the diagram, above, IRQ4 is assigned to UART A and IRQ3 is assigned to UART port B.


Figure 18: Shared IRQ Selection

To share the same IRQ on both UARTs A and B, short the pin labeled ‘S’ to its corresponding center pin, and jumper the desired IRQ for either UARTs A or B. In the example, below, IRQ 14 is assigned to both UART A and

UART B.

Note: Only one pull-down resistor is allowed per IRQ in the entire PC/104 stack.

UART Function and Power Selection

UART serial port B can be used to communicate with either a GPS receiver, for applications that require two GPS receivers, or the SocketModem TM .

Jumper J9 provides the mechanism for selecting UART port B to communicate with either the SocketModem TM or

GPS, and for selection the modem power option.

The following power options are provided.

•

•

+5V is required for all current models of the wireless SocketModems.

+3.3V is provided for future devices.

Note: The default jumper settings shown in the diagram apply to the CAN+UART and UART-only options.


Jumpered Pins Function

MDM (pair) Bottom position: Socket modem transmit (Tx) (default)

Top position: Socket modem receive (Rx) (default)

GPS (pair) Bottom position: GPS port 2 transmit (Tx)

Top position: GPS port 2 receive (Rx)

3V3 Select +3.3V modem power

5V Select +5V modem power (default)

Note: The transmit (Tx) and receive (Rx) pair of jumpers must both select either MDM or GPS.


The following figure shows examples for selecting either the socket modem or GPS, and for selecting either the

+3.3V or +5V power supply.
