EM1500 User’s Manual
75
The Opening tab for SER1 or SER2 is set to:
•
Local TCP port: 8889 (the default will do)
•
Remote TCP port: set this to the port number where TCP-Wedge is listening.
•
Remote host: set this to the IP address of the host PC where TCP-Wedge is running
•
Ephemeral port: arbitrary
•
Use Nagle: arbitrary
•
Don’t Purge: arbitrary
•
Incoming connections: Never accept
•
Active Open: When any char received
Since the EM1500 will act as a client, you don’t need to have a static IP address if you have a DHCP
server available to the EM1500. In this case, you may check Use DHCP on the Network tab to have a
dynamically assigned IP address. (The Network tab is also where you identify a statically assigned IP
address, which you may do instead of or in addition to DHCP.)
These settings cause the EM1500 to request a connection from the remote host when it first receives a
character on its configured serial port. Unless a closing condition occurs, the connection will, theoretically,
remain open forever.
6.2.2 Hardware Connections
Using a serial cable, connect either SER1 or SER2 to the free PC COM port. Now you need access to a
network. The EM1500 must be connected via its Ethernet port to a network to which the host PC is also
connected. It can be a small desktop LAN that you create with a hub and some crossover cables or an
already existing network. (If the host PC is not on the same LAN as the EM1500, you will need to fill in
the router information on the General tab in addition to the parameters described above.)
6.2.3 Software Setup
After the EM1500 has been configured, there are three additional programs to run:
•
Terminal emulator (e.g., Tera Term) - simulates a serial input device, such as a bar code reader.
•
TCP-Wedge - directs data coming in from Ethernet to a compatible Windows application.
•
Windows application that supports TCP-Wedge. Usually identified by a “Paste Special” command
in the Edit menu.
Open a terminal emulator and set it up to talk to the COM port you connected to the EM1500. This means
you must use the same serial port speed and geometry setting up the PC COM port as you did when setting
up the EM1500 serial port in
. Typically there is a main menu selection for doing this. In Tera
Term, for example, you select “Setup” from the main menu and then select the item “Serial port” to set the
configuration parameters.
