Flash Programmer Model TFP2 User’s Manual
3.1 POWER SUPPLY CONNECTION
The TFP2 is supplied with a universal AC/DC wall transformer. Alternatively, the TFP2 can be powered
by another external power supply. The TFP2’s power connector requires a 2.5 mm (inner diameter)
power plug. The center conductor is the +VDC and the outer conductor is Ground. External power
supply voltage range is +5VDC +/- 10% regulated. Maximum required power supply current is 200 mA.
NOTE: The TFP2 does not supply power at the Target-LS and Target-HS connectors. Power must
be supplied to the target board separately. The TFP2 must be powered first before connecting the
target board to the TFP2.
3.2 RS-232 SERIAL CONNECTION
For connection of the DB9 serial port to a PC, a straight cable must be used.

3.3 SERIAL CONNECTION SETUP
After connecting the DB9 serial port to a PC, start the HyperTerminal application and create a session
using 38400 baud, 8 bits, no parity, 1 stop bit, and XON/XOFF flow control. HyperTerminal can be found
by selecting Programs ? Accessories ? Communications from the Windows ? start menu. The
connection parameters are configured by selecting File ? Properties and then by pressing the Configure
button. If the Configure button is not active, select Call ? Disconnect. Port speed and flow control are
configured under the General tab, and bit settings are configured after pressing the Configure button, as
shown in Figure 3-3.
Figure 3-3: Port Speed, Port Bit Setup and Flow Control
Once, communication to the TFP2 is established, press the “Enter” key and the TFP2 program prompt “>”
should appear. Typing “ ? “ displays the TFP2 program help menu. Type “ V “ to verify that the TFP2
program version is revision 1.00 or later.
