Chapter 2 INSTALLING THE UTILITYMODULE
Since the utilityModule uses a PC/104 stackthrough bus, the only hardware installation you will do is placing the module to the PC/104 stack. To do this, you will connect the PC/104 bus connector with the matching connector of another module.
Recommended Procedure
We recommend you follow the procedure below to ensure that stacking of the modules does not damage connectors or electronics. * * * * * * * * Turn off power to the PC/104 system or stack. Select and install standoffs to properly position the utilityModule on the PC/104 stack. Touch a grounded metal part of the stack to discharge any buildup of static electricity. Remove the utilityModule from its anti-static bag. Check that keying pins in the PC/104 bus connector are properly positioned. Check the stacking order: make sure an XT bus card will not be placed between two AT bus cards, or it will interrupt the AT bus signals. Hold the utilityModule by its edges and orient it so the bus connector pins line up with the matching connector on the stack. Gently and evenly press the utilityModule onto the PC/104 stack.
CAUTION: Do not force the module onto the stack! Wiggling the module or applying too much force may damage it. If the module does not readily press into place, remove it, check for bent pins or out-of-place keying pins, and try again. Connecting the utilityModule The following sections describe connectors of the utilityModule.
Finding Pin 1 of Connectors
A white area silk-screened on the PC board indicates pin 1 of connectors. A square solder pad visible on the bottom of the PC board also indicates it.

PC/104 Bus Connectors, CN1 and CN2
Connectors CN1 and CN2 provide PC/104 bus connections. CN1 carries XT bus signals, and CN2 carries additional signals for the AT bus. The signals on CN1 and CN2 conform to the IEEE P966 standard for the PC/104 bus. The following tables list the connector pinouts: Table 5 PC/104 XT Bus Connector

Note:
Two locations on the bus have mechanical keying pins to help prevent misconnection of the PC/104 bus. These keying pins are a part of the PC/104 standard, and we strongly recommend you leave them in place. If you have other modules without keying pins, we suggest you modify them to include keying.
First COM port, CN3
The first serial port is implemented on connector CN3. It can be configured as a PC compatible full duplex RS232 port or as half- or full duplex RS422 or RS485 through mode jumper JP8. The I/O address is configurable in respect to SW1 address table, and corresponding interrupt is also selectable through jumper JP1 to be IRQ3, IRQ4, IRQ5, IR6, IRQ7, IRQ9, IRQ10, IRQ11, IRQ12, IRQ14 and IRQ15. But you need to make sure that there are no resource conflicts on the I/O base address and interrupt line you choose. The serial port is implemented with a 16C550-compatible UART (Universal Asynchronous Receiver/Transmitter). This UART is capable of baud rates up to 1.5 M with the 24 MHz clock input and 115.2K with the 24 MHz / 13 clock input.

RS232 Serial Port (Default)
The full-duplex RS232 mode is the default setting on the utilityModule. With this mode enabled, connector CN3 must be connected to RS232 compatible devices. The following table gives the connector pinout and shows how to connect to an external serial connector, either DB25 or DB9 compatible.

RTD Embedded Technologies, Inc.
RS422 or RS485 Serial Port
You can change the mode switch to set the first port as RS422 or RS485. In this case, you must connect CN3 to an RS422 or RS485 compatible device. When using RS422 or RS485 mode, you can use the port in either half-duplex (two-wire) or fullduplex (four-wire) configurations. For half-duplex (2-wire) operation, you must connect RXD+ to TDX+, and connect RXD- to TXD-. Note! Two 120-ohm termination resistors are provided on the utilityModule. Termination is usually necessary on all RS-422 receivers and at the ends of the RS-485 bus. If the termination resistor is required, it can be enabled by closing jumper JP8 5-6 for RxD and/or 7-8 CTS.
RS422 and RS485 Mode Pinout
The following table gives the pinout of connector CN3 when RS422 or RS485 modes are enabled.

Notes on using RS422 or RS485 Modes
When using the serial port in RS422 or RS485 mode, the serial receiver is always enabled, however the serial transmitter is enabled and disabled under software control in the following two ways. By default, the transmitter is enabled by manipulating the Request To Send (RTS*) signal of the serial port controller. This signal is controlled by writing bit 1 of the Modem Control Register (MCR) as follows: * * If MCR bit 1 = 1, then RTS* = 0, and serial transmitter is disabled If MCR bit 1 = 0, then RTS* = 1, and serial transmitter is enabled
For more information on the serial port registers, including the MCR, please refer to a standard PC-AT hardware reference for the 16C550 UART, or refer to RTDUSA application note ANC102 at http://www.rtdusa.com The other way to enable the serial transmitter is to write 1 to its corresponding bit of the utilityModule's internal common register 4, which sets the serial transmitter in "always on" mode. Please refer to Internal Common Register Section for detail.

CM312 common registers
The utilityModule includes 5 common registers to provide additional information and software control that is not required for normal COM port operation, but may be helpful in determining the status of the board and configuring of the board. The following two sections give the location and definition of the common registers.
Base Address of Common Registers
The utilityModule common registers are located 800h above the address of the first enabled COM port. That is, assuming that "X" in hex is the first enabled COM port base address, which can be any of the valid addresses listed in the Com Port Address Table, the base address for the common registers is "Y" in hex, then, Y = X + 800h For example, if the switches of SW4 are set all DOWN position which makes CN3 = 3E8h, CN4 = 2E8h, CN5 = 280h and CN6 = 288h, then according to the algorithm, the common registers base address (BA) will be the following depending the setting of enable switch SW2 for each serial port, If CN3 is enabled then, BA = 3E8h + 800h = BE8h Else if CN3 is disabled AND CN4 is enabled then, BA = 2E8h + 800h = AE8h Else if CN3 and CN4 are disabled AND CN5 is enabled then, BA = 280h + 800h = A80h Else if CN3, CN4 and CN5 are disabled AND CN4 is enabled then, BA = 288h + 800h = A88 A80h Else if CN3, CN4, CN5 and CN6 are disabled then, Common Registers are disabled End If

EXAR Documentation
Due to the complexity of the EXAR serial chip, it is impossible for us to reproduce all programming information in this manual. If you will be doing in-depth programming of the serial port controller, we suggest you obtain the 16C554D datasheet from the manufacturer. The 16C554D datasheet is available on-line in electronic format as an Adobe Acrobat (.

1.5 Mbps support
With 24 MHz clock input selected (JP5, 1-2), the utilityModule is capable of provide data rates up to 1.5 Mbps in RS422/RS485 mode. Since RS-232 standard restricts data rate to 20 Kbps, you might experience failure at higher data rate above 252 Kbps with 24 MHz clock select for the utilityModule.

Interrupt Sharing
Interrupt sharing is a mechanism which allows different devices sharing same active high IRQ lines on the PC/104 bus, given that there is a interrupt sharing circuit associated with each device. The utilityModule provides interrupt-sharing circuits for all the serial ports; thus it allows sharing of one IRQ line among the serial ports in the utilityModule. However, user needs to be careful to share an IRQ line with devices in the system elsewhere, and be sure that other devices also share their IRQ lines as well. For instance, users should be aware of that the IRQ3/IRQ4 associated with serial port J3/J4 on RTDUSA cpuModule are not shareable. And if the utilityModule is in the same system with RTDUSA cpuModule, be advised not to use/share IRQ3/IRQ4 for the utilityModule unless you have serial ports on the cpuModule disabled. Interrupt sharing in a PC/104 system requires one 1K pull-down resistor per IRQ line for all the devices that share the IRQ. Installing a G jumper in the utilityModule will pull its associated IRQ line down with 1K resistor. That is, for example, if IRQn is shared among four serial ports on the utilityModule, only one G jumper needs to be installed for IRQn line. If more than one G jumper are installed, the pull-down on IRQn line will be much stronger that expected 1K ohm, which will prevent interrupt controller from functioning correctly. Let consider two cases to demonstrate the concepts for the above discussion. Let us assume that IRQ5 and IRQ10 are not used and driven by other devices in the system. For the first case, IRQ10 line is shared among the four serial ports and for the second case IRQ5 is shared for port 1 and port 2, while IRQ10 is shared among port 3 and port 4. The following two tables listed the interrupt jumper settings for each case respectively. Table 11 Jumper Settings for interrupt sharing Case 1 Jumper JP1 G jumper JP2 G jumper JP3 G jumper JP4 G jumper Setting 13-14 Installed 13-14 Removed 13-14 Removed 13-14 Removed Function IRQ10 for 1st COM port 1K pull down resister added on IRQ10 from PORT1 IRQ10 for 2nd COM port No pull down resister added on IRQ10 from PORT2 IRQ10 for 3rd COM port No pull down resister added on IRQ10 from PORT3 IRQ10 for 4th COM port No pull down resister added on IRQ10 from PORT4

Chapter 4 USING THE UTILITYMODULE
ETHERNET PORTS
Using the utilityModule is straightforward, and essentially identical to any other Ethernet card. When CM312 module is powered on, data in the EEPROM on board is transferred to Ethernet controller's internal configuration registers. The data in the EEPROM contains information configuration such as the base address of the card, the active interrupt line on the PC/104 bus for Ethernet access, the media type in use, etc. The factory default setting of the board is at I/O address 0x320 and IRQ 5. And if there is a resource conflicting, you need to change your setting on CM312 with the other I/O boards removed temporally by executing CM312SET program as described in the later chapter. The following sections describe: * * * Diagnostic LEDs Boot ROM socket Power Consumption
Diagnostic LEDs
If CN8, the RJ45 connector, has two LEDs that are used to indicate status and provide some diagnostic information in case of malfunctions. Name COL LNK Meaning Collision Detected Link established (UTP) Normal State Off On (10Base-T only)
COL LED
The LED is normally off, and flashes when the module detects a collision on the network. Collisions may be due to low-quality cable, which allows crosstalk between the transmit and receive pairs, miswiring, or a malfunctioning device on the network.
LNK LED
The LED is turned on when a valid 10Base-T link is detected by the chipset. It is only active when using the 10Base-T UTP connection with link integrity checking enabled. If it is off, the UTP wiring may be broken or incorrect, link integrity checking may be disabled, or you may be using the 10Base-2 or AUI interface.
Boot ROM Socket
In some applications, you may wish to use the boot ROM socket of the utilityModule to boot a connected cpuModule from a remote server. The socket will accomodate a 32 pin PLCC EPROM or Flash memory devices of size 8k, 16k, 32k, or 64k bytes. The device must be a byte-wide architecture. The boot ROM feature can be enabled using the CM312SET program described on page 28.

Chapter 5 SOFTWARE
INSTALLATION
This chapter contains information on: * * * * * Software installation The CM312SET Program Server Examples Client Examples Client Remote Boot Examples
Software installation
There is no installation program for the supplied software. We suggest you create a directory named /CM312 on your target drive, and copy all files and subdirectories from the supplied floppy disk into that directory.
The CM312SET Program
The /TOOLS directory of the supplied floppy disk contains the setup and diagnostic utility, CM312SET.EXE.
Using CM312SET
Since CM312 utility module is a jumperless I/O board, complete software configurable with all its configuration data stored in EEPROM, CM202SET is a utility program that let you view or change the existing setting of the board. When you run the CM312SET program, the utility looks at all possible I/O addresses. If no module is found or if there is a conflicting, the utility quits with a message. When the module is found and correctly operating, the utility displays lines indicating the active I/O address, the interrupt, the Media Type in use, the compatibility mode selected (NE2000 or NE1000), and the MAC address of the board. You can use the program to change settings for I/O address, Interrupt, Media Type, Remote Boot Prom, and compatibility mode and save your selection either into the configuration registers or to both registers and EEPROM. Saving to registers only will allow you to perform test with the settings in your system, but the settings will be lost when power off. In order to change the setting for future operation, you need to save your changes to both registers and EEPROM. These settings then are recalled from EEPROM whenever the module is reinitialized.
NE1000 Mode
NE1000 mode can be used to allow the utilityModule to operate with an 8-bit (XT) cpuModule. In NE1000 mode, only IRQ2, IRQ3, IRQ4, IRQ5 are available. You cannot use IRQ10, IRQ11, IRQ12, IRQ15 with an 8-bit system bus.
