Instructions for Configuring ASEK-21-T-KIT for Device Programming

1. Connect one end of the USB cable to a personal computer

2. Connect the other end of the USB cable to the USB port on the ASEK-21.

3. Connect the DSUB62 cable to ASEK-21 and the other end to J4 connector on the ASEK-21

daughterboard board (85-0712-103).

4. Connect the DC Power Supply/Cable to the 5V port on the ASEK-21.

5. Plug in the DC Power Supply to a 110V/220AC 60/50Hz outlet with the proper adapter

6. Complete setup is shown in Figure 2

Daughterboard Pinout and Jumpers

It is advised to remove all 4 jumpers in the image below, and place them on one side of the pins

for safe storage. Jumpers may be necessary in very specific applications (RS232, sensor

modules without i2C pull up resistors).

ASEK21 daughterboard supports multiple communication protocols. Figure 3 below shows test

points for analog, i2c and SPI communications. Note: Analog test REQUIRES the connection of

kelvin contacts either on the daughterboard or at the sensor module.

Figure 3: ASEK21 daughterboard

Refer to Table 1through Table 4below for daughterboard pin names and brief description of

their function. Refer to Table 5for information regarding jumpers.

Setting up USB Connection

Figure 4: Options for Connecting ASEK to PC

Windows will treat ASEK21 as a serial com port. The first time ASEK-21 is connected to the

computer windows will look for and install the necessary drivers. The exact port number can be

found using the device manager under “Ports.” See Table 5.
