SCP1000 DEMO KIT 

User Manual 

Using the SCP1000 demo without the GUI software 

SCP1000 DEMO KIT can be used also without the GUI software. Serial communication between 
the SCP1000 USB demo and PC can be controlled with the GUI software or by Windows 
HyperTerminal software (serial virtual com port driver converts the USB demo to a COM port 
device). 
 

5.1  Establishing the connection 

After the SCP1000 DEMO KIT USB serial com port driver is installed, the HyperTerminal 
connection can be opened from SCP1000 demo CD-ROM or from:  

 Start 

 Programs 

 Accessories 

 Communications 

 HyperTerminal 

 
The communication settings are presented in Table 2 below 

Table 2. SCP1000 USB demo HyperTerminal communication settings. 

Parameter 

Value 

Bits per second 

38400 

Data bits 

Parity None 
Stop bits 

Flow control 

None 

 
The correct COM port number depends on the PC and used USB port. 
 
Please notice that GUI software and Windows HyperTerminal software can not be open at the 
same time. Follow the steps below to open the HyperTerminal connection: 

1.  Connect SCP1000 DEMO KIT with USB cable to PC 
2.  Open GUI software to see the correct COM port number (SETUP display, see Figure 10). 
3.  Close the GUI software. 
4.  Open the pre-configured Windows HyperTerminal software from the DEMO KIT CD-ROM: 

SCP1000_Demo_pre-configured_HyperTerminal_connection.ht  

5.  Type ' * ' (asterisk character), the SCP1000 DEMO KIT sends an info text to HyperTerminal 

(see Figure 11). If the HyperTerminal software is unable to connect the SCP1000 DEMO 
KIT or the info text does not appear,
