The controller also includes a real - time clock and a watchdog timer function. The real - time clock ensures time recording while events occur. The watchdog timer is designed to automatically reset the microprocessor when the system fails. This feature greatl y reduces the level of maintenance required and makes the ADAM - 4500 ideal for use in ap[...]

Figure 2 - 5: Emulating Screen of ADAM - 4500 2.3 Jumper Setting We designed the ADAM - 4500 with ease - of - use in mind. It has three jumper settings. The following sections explain how to configure the module. You may want to refer to the figure below for help in identifying card components. The following diagram shows th e locations of the jump[...]

The ADAM - 4500 has a DB - 9 pin connector as its RS - 232 port connector. Since the connection for an RS - 232 interface is not standardized, different devices implement the RS - 232 con nection in different ways. If you are having problems with a serial device, be sure to check the pin assignments for the connector. The following table shows the [...]

mini BIOS of ADAM - 4500 o nly provides 10 function calls. Since the user's program can not use other BIOS function calls, the ADAM - 4500 may not work as intended. Additionally, certain language compilers such as QBASIC directly call BIOS functions that are not executable in ADAM - 450 0. The ADAM - 4500 mini BIOS function calls are listed in[...]

Figure 3 - 1: Converting Program Codes Other Limitations 1. The ADAM - 4500 does not support the standard PC function "8253". Therefore, the C language function call "delay ( )" cannot be used in ADAM - 4500 applications. 2. Certain critical files are always kept in flash ROM, such as the operating system files, B IOS, and monit[...]

You can tran[...]

Step 3: Convert a nd download codes to flash ROM Within the host computer, convert the application program into 80186 or 80188 compatible code. Create an AUTOEXEC.BAT file for the application program and write the application program's name in the AUTOEXEC.BAT file. Also create COMMAND.COM and CONFIG.SYS files for the application program.

Syntax: int comm_init(int buf_size) Function description: Initializes the communication port and interrupt routine before other function calls use the communication port. Parameter Description int buf_size Sets the buffer size of every communication port for storage of received data. The unit of size is bytes. Return: Returns a 1 if command succeed[...]

int stop Stop bits setting 1, 2 (stop bit = 1 is for data bits = 5,6,7, or 8) (stop bit = 2 is for data bits = 6,7, or 8) For details, refer to RS - 232 chip set data book int cmd_type Received data format setting. 0: single byte mode. The data format is a single byte character. User can use comm_get_rec_datas to receive single byte data. 1: comman[...]
