Installing Pen Tablet with RS232C Interface
Before attempting to install the Pen Tablet on your computer, please check that the system requirements are all met. This section
describes the installation procedure for Pen Tablet with RS232C Interface. If you
have a Pen Device with USB interface, please see Installing Pen Device with USB
Interface.
You attach the Pen Tablet to the computer by inserting the Pen Tablets Keyboard
Connectors between the keyboard and the computer, and by connecting the Pen Tablets
RS232C Connector to an available COM (serial) port. The procedure is described
below.
- Shut down Windows and turn off the power of your PC.
- Examine the connecting parts of the Pen Tablet.

Figure 3 Parts of the Pen Tablet for connecting to the PC
- Locate where the Original Keyboard Connector attaches to the computer. In the
figure 4 below, we assume it is in the back of a desktop PC. Examine the size of the
keyboard connector (see figure 5 below).

Detach the Original Keyboard Connector from the Keyboard Socket, and remember the
location of the Keyboard Socket so you can find it later. Examine the connector and try to
match one of the pictures in the figure below. If it matches Small Connector, go to the
next step. Otherwise, you need to find two Keyboard Acaptors (not included) so the
connectors will match.

Figure 5 Identifying the Keyboard Connector
- If your keyboard has a small (PS/2) connector (see figure above), connect the Original
Keyboard Connector to the Female Keyboard Connector (the one connected with a single data
cable). Then, connect the Male Keyboard Connector (the one with a split data cable) to the
PC at the Keyboard Socket to which the keyboard was originally attached. Go to Step 6.

keyboard
- If you have a notebook PC, connect the Male
Keyboard Connector (the one with a split data cable) to the PS/2 Port. If there is
an external keyboard (assuming it uses a PS/2 connector), and you wish to keep it, you
should then attach the Original Keyboard Connector to the Female Keyboard Connector (the
one with a single data cable). See figure below. Go to Step 6.

- Take the 9-pin RS-232C Connector running
from Tablet Plate and insert it into COM1 port of the computer. If COM1 is in use, for
example, by a mouse, you may plug into COM2 port instead. In this case, since many
COM2 ports require a 25-pin connector, you will need to find a 9-pin-to-25-pin adaptor
(not included). Also, if your computer has a built-in modem using one of COM1, COM2, COM3,
and COM4 ports, please seek help from a professional to ensure that the Pen Tablet can
indeed use an apparently unused serial port. A built-in modem may use up a COM port which
is shared by an outside COM port socket. The Pen Tablet requires a free COM port to
operate, and it can co-exist with a mouse and/or a modem connected to a different COM port
not in conflict with the port used by the Pen Tablet. If the mouse uses a PS/2 port, it
will not conflict with any COM port.
- Turn power on and wait for Windows to start up.
- Verify that the Pen Tablet hardware functions properly.
The hardware installation is now complete. Please proceed to install
the Driver and Pen Utilities that provides pointing device function and Pressure
Sensitivity (through a Wintab-compatible interface), plus additional pen functions with
Pen Utilities such as Annotate All, Annotate for Word, PenSigner,
PenMail, and PenCommander.
