PC, then press <enter>. The Baudrate is set to a default value of 5 7600 bps and cannot be changed. The screen is as shown in figure 2.4. Figure 2 - 4: Select Communication Port Step 4: Power on ADAM - 4500 Highlight the "Terminal" option, then press <enter>.
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 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.
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.
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.

executing, select the COMport of the host PC that has been connected to ADAM - 4500. Then select "Program" from the bar menu and press <enter> to begin downloading. The screen shown in figure 3 - 2 will appear. Figu re 3 - 2: Program downloading Follow the instructions shown on the screen.
Figure 3 - 3: Download Complete Transferring files to SR AM (ADAM - 4500's D - drive) The ADAM - 4500 provides 234 KB of free SRAM for use in program operation, and as working memory space in the event you want to test your system control logic or simulate system performance before downloading the execution code to t he flash ROM.
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.
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.
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.
