5) Connect a cable from the computer's serial port to the C module. If using a 9-pin serial port, use a straight-through, 9-pin, female-to-male cable. If the only available serial port uses a 25-pin connector, a standard 25-pin to 9-pin adapter is required. The EV kit software checks the modem status lines (CTS, DSR, DCD) to confirm that the correct port has been selected. Start the MAX1241 software on the IBM PC by setting the current directory to match the directory containing the Maxim programs, then type the program name "MAX1241". Do not turn off or disconnect the C module while the program is running; if you do, you will have to restart the program. The program will ask which port the C module is connected to. Press the space bar until the correct PC serial port is highlighted, then press ENTER. The MAX1241 program will be in terminal-emulation mode. Turn on the power for the C module. The module will display its logon banner and test its RAM. Download and run the RAM resident program on the C module by pressing ALT+L (i.e., hold down the ALT key as you strike the L key). The program prompts you for the file name. Press the ENTER key to download and run the file.
Systems Using 3V and 5V Logic
Systems that have both 3V and 5V logic must provide level translation for the MAX1241's data output. No level translation is necessary on the inputs.
Changing the Reference Voltage
The MAX872 is a 2.5V reference. To supply a different external reference, open JU2 and apply the reference voltage between VREF and GND. Refer to the MAX1241 data sheet for reference voltage requirements.

Table 2. Command Reference
KEY C FUNCTION Display the input codes in decimal format. Delay between samples. Delays longer than one second are handled by the IBM PC; otherwise, the C module handles the delay. Timing is approximate and should be verified with an oscilloscope. Enable or disable data logging. If the -L command-line option was not specified, the L command prompts for a log-file name. Oscilloscope demo. Samples are collected and discarded as quickly as possible. Observe waveforms and timing with an oscilloscope. Power-up delay. Timing is approximate and should be verified with an oscilloscope. When VREF = VDD, power-up delay is not necessary and should be set to zero. Power-up delay is used regardless of which power-cycling mode is selected. Sample the input at high speed. The sampling rate is controlled by the P and D delays. Due to program overhead, the O and S commands operate at different rates. Timing should be verified with an oscilloscope. Display the input voltages. Write a marker into the data-log file. Change the assumed value of VREF. Select power-down mode. Switch back to terminal mode. Exit to DOS.
Table 3. Command-Line Options when Starting MAX1241 Software
COMMAND 1 2 MONO -Lfilename FUNCTION Default to COM1 PC serial port. Default to COM2 PC serial port. For use with LCD or monochrome display. Open file "filename" for data logging, and enable the data-logging commands. Specify the actual measured voltage at the REF pin (nominally 2.5V). List command-line options.

____________________Getting Started
All system components are guaranteed by their various manufacturers over the +3V to +3.6V power-supply range. Not all system components are guaranteed over the entire 2.5V to 5V V DD power-supply adjustment range. Verify correct operation using the following procedures: 1) Connect a +5V DC power source (16V max) to the C module at the terminal block located next to the on/off switch, in the upper-right corner of the C module. Turn the power switch on. 2) Connect a cable from the computer's serial port to the C module. If using a 9-pin serial port, use a straight-through, 9-pin, female-to-male cable. If the only available serial port uses a 25-pin connector, a standard 25-pin to 9-pin adapter is required. 3) Start the evaluation kit software on the IBM PC. When the program asks which port the C module is connected to, press the space bar until the correct port is highlighted, and then press ENTER. The software will be in terminal-emulation mode. (If using a generic terminal-emulation program instead of Maxim EV kit software, select 1200 baud, eight-bit character, no parity, one stop bit. Send a space character to start the monitor program.) 4) Adjust trim potentiometer R2 for the desired VDD supply voltage. Measure V DD between test point TP1 and ground. The mounting hole next to R2 is grounded. 5) To verify correct system operation, press the ESC key, type a capital "T", and then select the countdown memory test. If the memory test fails or any other malfunction is reported, the VDD voltage is too low; increase VDD and repeat from step 4. 6) Turn the power switch off and connect the C board to an appropriate Maxim EV kit board.

68L11D Module 68L11D Module
_______________Detailed Description
Power Requirements
The 68L11D module draws its power from a user-supplied power source connected to terminal block J2. Note the positive and negative markings on the board. Nominal input voltages should be between +5V and +16V. The input current requirement for the 68L11D module is typically 20mA plus the current drawn by the evaluation kit (EV kit). The VDD supply is set by U4, a MAX667 low-dropout CMOS regulator. Trim potentiometer R2 sets the supply voltage, with an adjustment range of approximately 2.5V to 5V. Although the board is designed primarily for 3V applications, all of the circuitry is rated to withstand 5V levels. The 20 x 2-pin header (J1) connects the 68L11D module to a Maxim EV kit. Table 2 lists the function of each pin. Use the 68L11D module only with EV kits that are designed to support it, and download only code that is targeted for the Maxim 68L11D module. Downloading incorrect object code into the 68L11D module will produce unpredictable results. The 8k x 8 boot ROM (U10) checks the system and waits for commands from the host. Refer to the EV kit manual for specific startup procedures.
Software
All software is supplied on a disk with the EV kit. Software operating instructions are included in the EV kit manual.
Serial Communications
J3 is an RS-232 serial port, designed to be compatible with the IBM PC 9-pin serial port. Use a straight-through DB9 male-to-female cable to connect J3 to the IBM PC serial port. If the only available serial port has a 25-pin connector, use a standard 25-pin to 9-pin adapter. Table 1 shows J3's pinout. The hardware-handshake lines are used by the evaluation software to confirm that the EV kit is connected to the correct serial port.
68L11D Microcontroller (C) Module Hardware
U1 is Motorola's 68L11D C. Contact Motorola for C information, development, and support. A MAX708R supervisory circuit on the module monitors the VDD logic supply, generates the power-on reset, and produces a reset pulse whenever the manual reset button (SW2) is pressed. Note that the MAX708R resets the CPU if the supply voltage falls below 2.66V. The module provides 32kbytes of external CMOS static RAM (U5). The 74HCT245 octal buffer (U6) provides access to an eight-bit port on the 40-pin interface connector. This memory-mapped port consists of Intel-compatible read and write strobes, four chip selects, four address LSB's, and eight data bits. Table 3 lists the address ranges for each of the memory-mapped elements on the 68L11D module. The MAX3232 is a 3V-powered, RS-232 interface voltage-level shifter. Its built-in charge pump uses external capacitors to generate the output voltages necessary to drive RS-232 lines.
