Frequent problems:
1. There is no free COM serial port connector available on the PC
•
The PC must have one free serial port for connecting the cable: COM 1...8. The COM port is also called as standard
serial port. This port is used by the old mouse, external modem and other devices and programs communicating
across a serial line. So does the EL-Link as well.
•
COM (serial) port of the computer is a 25 or 9 pole big D letter formed socket on the back wall of the computer,
connected to a communication card inside the machine.
•
If you have no free COM port, then remove modem cable or connector of another equipment from the port being
engaged. You can employ another serial communication (COM) card.
•
If there is only USB port (Universal Serial Bus) in your PC, it is necessary to employ the serial communication
(COM) card. If you have a notebook, then in addition you can employ an USB to COM converter only, or PCMCA-
COM card.
2. The computer cannot find the cable or the unit
◊
The program requests EL-Link cable after starting menu points Communication  Receive, Send,
Synchronize, Backup save, Restore.
◊
The text EL-Link or SHARP is not written to any of the COM ports after cable detection in the window
Options  Communication parameters (Free, None, Reserved, Internal device, etc.).
•
If the Your cable not EL-Link type, the SHARP text only in case will be visible at the COM port in the
Communication parameters window, if you click to the ”Cable detection” button! In case of EL-Link cable use the
EL-Link software find the cable automatically even if the SHARP unit is not connected.
•
Connect the cable to the COM (Serial) port, and check the connection. If there is another COM port on the PC,
connect the cable there.
•
If the words "None" or "Error" are displayed at the COM ports, they should be enabled at the communication
board. This can be performed in the Bios Setup program in case of ports integrated in the base board (Bios Setup can
be approached by pressing Del key during the starting procedure of PC). The older, separate boards can be enabled
by rejumpering, supposing there is a description on the communication board.
•

System window, and check whether exclamation mark exists next to the COM port. If visible, then
examine this COM port (click on it), and clear the problem indicated.
•
If the words "Internal device" or "Reserved or None" are displayed at the COM ports, probably the port is
reserved by some other internal device, therefore such devices have to be installed and setup that if possible keep
the COM1, COM3 port with IRQ4 IT, or COM2, COM4 port with IRQ3 IT. It is practical the card device to be
jumpered to IRQ5 or IRQ7 interrupt and the COM3 or COM4 port.
•
If there was a device installed to the COM port before EL-Link e.g. mouse, modem or other link cable (Nokia phone,
handled PC, PDA), then driver of this equipment must be removed: write the word REM before the driver program in
the files Autoexec.bat or Config.sys - e.g. REM mouse.sys and restart the machine. Under Windows 95 or latter
version look for small icon in the right corner of Taskbar, and if the above COM driver program exists, it must be
removed by right button click of mouse to the icon, and select the close or other remover menuitem. For final
removing the Start icon

•
If the word "Free" appears at the COM ports, it means that the cable connecting the (not ATX) motherboard (or
communication card) and the back wall connector is broken or is connected inversely to motherboard or the binding-
in system of this cable different from the motherboard connector or maybe the link cable connector is not connected
properly.
•
If the Your cable not include electronic circuit (that is not EL-Link cable), can be happened that the PC not find the
SHARP because of different signal level. The signal level of the EL, ZQ units smaller than of PC (3V < 12V) and
because of this the signal of SHARP die away in the insensitive PC. The only resort for this problem the use of EL-
Link cable, which include electronic circuit (http://web.interware.hu/pclink/aellkab.html).
•
If the problem cannot be solved in no way, try the EL-Link or other PC-link cable with another PC.
