It is a Condition of Sale that the user of Octagon products in life support applications assumes all the risk of such use and indemnifies Octagon against all damage. -
Page 3: Using Cmos Circuitry In Industrial Control
Multiple component failures: The chance of a random component failure is very rare since the average MTBF of an Octagon card is greater than 11 years. In a 7 year study, Octagon has never found a single case where multiple IC failures were not caused by misuse or accident. -
Page 4: Avoiding Damage To The Heatsink Or Cpu
CPU control card sequences properly and avoids system lockup. Excessive signal lead lengths: Another source of failure that was identified years ago at Octagon was excessive lead lengths on digital inputs. Long leads act as an antenna to pick up noise. They can also act as unterminated transmission lines. -

running a program on the XE–800 SBC that will ultimately be used on another card without on-board video, you might want to remove the video jumper and still use COM1 as a COM port instead of a serial console. In this instance, you must go into Setup and set Serial Video in the Advanced menu to Disabled. -
Page 48: Typical Rs-485 4-Wire Interface Circuit
In any given communication sequence in an RS–485 network, there can only be one host. The host is responsible for initiating communication, maintaining network registration, and providing housekeeping tasks with other nodes. Remotes, however, cannot initiate a communication. They can only respond to messages that are addressed to them from the host. -

Page 78: Chapter 14: Watchdog Timer And Hardware Reset
Chapter 14: Watchdog timer and hardware reset Description The watchdog timer is a fail-safe against program crashes or processor lockups. It has a programmable timeout period, ranging from 2.0 milliseconds to 2 minutes (see next section). The watchdog timer can be enabled or disabled in Setup. INT17 software calls, a built–in function on the XE–800 SBC, can also be used to enable and set the timeout, extend the timeout, strobe, and disable the watchdog timer from your application. -
Page 79: Watchdog Function Definitions Using Enhanced Int 17H Handler
The INT17 handler is designed for DOS based applications. If you use a different operating system and the watchdog functions are required for your application, source code is available on the Octagon Product CD-ROM to access the watchdog. OS Development Kits are available from Octagon for Linux, QNX, and Windows CE.net that have watchdog drivers for these operating systems. -
Page 80: Strobe Watchdog
Strobe watchdog Function: Subfunction: Purpose: To strobe the watchdog. Calling registers: ffffh Return registers: None Comments: This function strobes the watchdog. Once the watchdog is enabled, it has to be strobed at least twice per timeout period or until the watchdog is disabled. -
Page 81: Hardware Reset
Hardware reset The reset switch (Switch SW1) allows you to reset the system without turning off the power. This provides a more complete reset than the <CTRL><ALT><DEL> method. Depressing this button pulls the circuit to ground and resets the system. The RESET command accomplishes the same thing as the reset button. -

The “S” jumper selects whether the card boots from user defined parameters (defined in the Setup Programs chapter), or the BIOS defaults. Removing this jumper allows the user to return to factory programmed defaults. -
Page 87: Extended Bios Jumper
Extended BIOS jumper The extended BIOS jumper is W1[3–4]. The extended BIOS memory region (D8000h to DFFFh) contains the Octagon INT17 functions. When this jumper is removed, this memory region is freed up for other uses. Note that if you want to use the INT17 functions, you must either leave the jumper installed or copy those functions elsewhere. -

6. Power up the XE–800 SBC. If you have a post card, you can place it on the XE– 800 SBC PC/104 bus and the system will boot to a post A1, or you can allow about 5 seconds for the system to boot to the boot block recovery state. 7. - Page 89 MOV AX, 0fb0bh MOV DX, 0ffffh INT 17h MOV aData, AL if (aData & 1) printf(“U1 jumper is ON\n”);...

connector to the monitor. If using a flat panel display, check the following: Check the power and cables going to the flat panel display. Make sure that the power module has enough current capacity to power both the XE–800 SBC card and the flat panel. If a flat panel BIOS has been programmed into the XE–800 SBC that is incorrect for the flat panel being used and an analog monitor is not present or is not displaying the video data correctly, the system can be booted via the... -

No serial console activity If the serial console does not appear to be functioning correctly, check the following: Make sure all PC/104 or PC/104 Plus expansion cards are removed from the XE–800 SBC. This ensures that other cards are not interacting with the XE– 800 SBC. -
Page 93: System Locks Up On Power-Up; May Or May Not Respond To Reset Switch
System locks up on power-up; may or may not respond to reset switch A common cause is using a non-Octagon power supply such as a PC desktop supply. Most of these PC supplies are rated at 5V at 20A or more. Switching supplies usually requires a 20% load to operate properly, that is, 4A or more. -

This card is guaranteed to operate over the published temperature ranges and relevant conditions. However, sustained operation near the maximum temperature specification is not recommended by Octagon or the CPU chip manufacturer due to well known, thermal related, failure mechanisms. These failure mechanisms, common to all silicon devices, can reduce the MTBF of the cards. -
