Installation
The keypad connects to ViconNet or VMDC as a serial device via its USB
cable. Power is provided via this same USB. Up to 5 keypads can connect to
the same VMDC or ViconNet PC. Simply insert the USB cable on the keypad
into a USB slot on the ViconNet/VMDC unit.
Modifying the Serial Port Number
The Windows OS allows for mapping of the serial ports. Regardless of the
hardware configuration, each serial port can be assigned a COM number from
1 to 256.
When installing on Windows environment, the OS will automatically assign a
port number which may not necessarily meet the needs of the user.
To change the serial port number:
1. Connect and install the VN-KEYPAD.
2. Go to the settings in
Control Panel/System/Hardware/ Device
Manager
.
3. Scroll the list of peripherals and select
Ports (COM and LPT)
. The
USB CDC serial port emulation (COMx)
port corresponds to the
VN-KEYPAD.
4. If there is no issue with the assigned number, close the dialog box. If a
change is required, proceed to step 5.
5. Click on
Property
for the required port.
6. Go to
Port settings/Advanced
and change the port number in
COM
port number.
Some ports may indicate they are
in use
by other
devices, though this is not usually the case. If you select a port
in use
,
check whether other devices (for instance an analog modem) are
already using it.
7. Press Confirm and exit.
8. After changing the port number, the
Device Manager
tab may still
indicate the old COM number.
9. Close the
Device Manager
tab and then re-open it to see if the number
has been changed.
