The HHC will appear as a Communications Port on a Windows

PC. It will be assigned the port number of the first available port

on the PC. To determine which port number has been assigned

look in the Windows Device Manager. This can be accessed by

the Windows Control Panel under System or by right clicking

on your My Computer Icon, selecting Properties and Device

Manager.

In Device Manager expand Ports to see which USB Serial

Port is assigned to the HHC. In the example below the HHC is

shown as COM 8. You may connect more than one HHC to a

PC; each will have its own COM Port assignment.

Terminal or Programming environment setting

The Com Port Selection in the software must be set to the com

port number shown in Device Manager. This Com Port appears

only while the HHC is connected.

Configuration Settings to use:

9600

8 Data Bits

1 stop

No Parity

No handshaking

Note for Terminals: The HHC does not echo characters

received, the user may want to enable local echo.

Modes of Communication:

The HHC can automatically determine which of its three modes

is to be used (Inquiry/Journal, ISO1745 or MODBUS). After

Power-on the HHC uses the first received command from the

PC to establish which mode it will operate in. It will recognize

the format of the first command and remain in that mode until

switched by the user via the Setup Communications Mode

MENU or the next power off/on.

Set up of the HHC Communication modes are available

through the programming MENU.
