HyperTerminal
HyperTerminal is a communications utility program included with
Microsoft® Windows® XP.
Notes:
 If you are using a version of OpenBSI older than 5.1, or do not have
OpenBSI software, you can only perform a firmware upgrade using
HyperTerminal.
 While HyperTerminal is included in Microsoft® Window® XP,
some newer versions of Window® do not include it.
 The screens shown here may appear different depending upon the
version of HyperTerminal you use.
 HyperTerminal requires *.BIN files; newer ControlWave firmware
upgrade files use *.CAB files. In cases such as those, you should use
the Remote System Firmware Downloader.
1. Connect a null modem cable between COM1 of the
ControlWave GFC Plus and any RS-232 port on the associated
PC.
2. Click Start > Programs > Accessories > Communications >
HyperTerminal
3. If using HyperTerminal for the first time, set the communication
properties (for the PC port) via the Properties Menu as follows:
Bits per second: = 115200, Data bits: = 8, Parity: = None, Stop
bits: = 1, and Flow control: = None and then click OK.
4. Set CPU/System Controller board switch SW1-3 ON (ON =
Force Recovery).
5. Apply power; to the ControlWave GFC Plus. The resident BIOS
initializes and tests the hardware, this process is referred to as
POST (Power On Self Test). Unless there is a problem, the LCD
display should show RECOV. If you see a different status code,
see Section 5.3.2.
6. From the HyperTerminal Mode menu (Figure 5-1), press the F
key to enter FLASH download. A message warns that the
FLASH is about to be erased; press the Y key at the prompt. The
screen displays dots as the system erases the flash memory; this
could take a few minutes.
