Maybe you are using a serial-to-usb converter cable and you havn't installed the drivers for that. It should be some sort of mini-cd in the box.
If not, then you need to provide more information so people can help.

If this is a USB unit, and you have moved the plug from one port to another, this situation occurs. I would disconnect it, reboot the PC and reconnect it again.
Good luck!

My older hi-pro box will not work with my serial to USB adapter. It keeps saying it cannot find it on com 1,2,3,4. In the device settings it says the hipro is on port 2 and the serial/USB bridge is on port...


I just set up a serial Hi-Pro box for one of my customers on their new laptop. According to Beltone, the only usb adapter that will work with the Hi-Pro (or at least the only one they have gotten to work) is a Belkin F5U409. I know some usb serial adapters don't use true serial communications if that makes any sense, so there isn't really a baud rate. They kind of just send out the communication in bursts...

In any case, ive only tried with the belkin adapter and that worked fine with no problems. The other point here is that your Hi-Pro and Adapter are on different com ports... This is odd, the hi-pro should be on the serial adpater's com port. Also the software i was using - Noah, with a beltone module for programming hearing aids.. only looked on com ports 1-3. The computer put the serial adapter on com 8 - which would not do. I checked for available com ports and saw that 2 was unused. I set the adapter to 2 and was able to set up the program normally.

I did this on Windows 7 Professional 32 Bit. The procedure for selecting the com port is the same on earlier versions of windows.

First, open device manager, open the list titled "Ports (COM and LPT)". You should see your serial adapter in there. Double click it. In the window that opens click the "ports" tab, and hit the button labeled "Advanced" In the window that opens there will be a drop down list to select a com port. Select the desired com port and hit ok. That should fix it.

Com.port failed


Download and install the latest proper driver for the TU-S9 cable.

Also, are yo sure that this mysterious "external serial device" is working properly, or is even compatible with the computer?

Last but not least, you could buy and install a PCI serial port card...

Cash Drawer Command


The cashdrawer is SERIAL, you'll need to connect it to a COM port. The
software you're using has to be capable of sending data to the COM port
the cashdrawer is connected to when the cashdrawer needs to be opened.
From the site you mentioned:

Be sure drawer lock is not engaged.
Exit your system to a DOS prompt. Type the following commands (substitute
the correct com port for com1):
c:\>mode com1:300,n,8,1
c:\>echo "000000000000000000000">com1
The cash drawer should open.

About the cashdrawer RJ11 connection on the printer: You can connect any
solenoid driven cashdrawer to this port. The port uses pin 2 and 4 for
the voltage output, which is normally 24V on Epson receipt printers.
Sending a specific ESC character (every POS software should be capable of
doing this) to the printer will be recognized by the printer and the
printer puts 24V on the 2 pins mentioned for 300ms and voila, the drawer
opens.
