Setup
Intermec EasyCoder E4 – Installation & Operation Ed. 2
The EasyCoder E4 can receive data on both the parallel and serial
port, so there is no need to specify which port is to be used:
• Either compose a text fi le containing the required setup commands
and send it to the printer via the parallel port,
• or establish two-way serial communication between printer and
host computer as described below.
To set up two-way serial communication with the EasyCoder E4:
1 Print out a test label to check the printer's RS-232 serial port setting
(see Chapter 3, "Operation; Printing Test Labels.)"
2 Confi gure the serial port on your host computer to match the
printer's settings.
3 Use the SYSVAR(18)= n command to set what kind of
information will be passed back from the printer (called the
Verbosity Level.)
4 Use the SETUP command to confi gure the serial port settings.
SYSVAR Verbosity Level settings:
-1 All levels enabled (Default)
0 No verbosity
1 Echo received characters
2 "OK" after correct command lines
4 Echo input characters from communication port
8 Error after failed line
Bits can be combined so for example SYSVAR(18)=3 means
both "Echo received characters" and "OK after correct command
lines" .
Once the printer and computer can communicate using the default
serial port settings, you can change the settings to whatever
communications settings you require, fi rst on the printer and then
on the computer.
Once you have established a working serial communication both
ways between printer and host, you can use the command to
confi gure the printer as described on the following pages.
