Communication Setup

Intermec EasyCoder E4 – User's Guide
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 com-
mands and send it to the printer via the parallel port,
• or establish two-way serial communication between printer
and host computer as described below.
How to set up two-way serial communication with the Easy-
Coder 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), see below
4 Use the SETUP command to confi gure the serial port set-
tings.
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 what-
ever 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.
