6.3 Configuring the Remote
Interface Settings
Note that the menus displayed in this section show the default settings.
Before you start, ensure that the printer is in the “Jet Off” state. To verify
this, check the Status in the PRINT STATUS screen.
6.3.1 Transfer Parameters Menu
The Transfer Parameters menu options define the general parameters for
the RS232 link:
Figure 6-2 Transfer Parameters Menu
The TRANSFER PARAMETERS MENU includes the following
options:
• Mode
This option displays the communication protocol name.
• Escape Char
This option defines the character that is used by the RS232
communications protocol to identify the delimiting characters for the
start and end of data transferred to and from the printer. Any value
between 01 and 31 can be set. It is also used to identify other ‘special’
data characters. This is described in further detail in the Linx Remote
Communications Interface Reference Manual (FA76014).
NOTE: Special characters are used for various tasks in the interface
and, as with the escape character, may be set to any value
between 01 and 31 (ASCII control characters SOH to US).
No two special characters may have the same value. If an
attempt is made to set two special characters to the same
value, a warning is given and displayed in the status line.
• Checksum Disabled
This option allows you to disable the insertion of checksums at the end
of data transmitted from the printer, by setting the option from No
(default) to Yes. The printer does not look for checksums on the end of
received data. It is recommended that the Yes setting is not used
continuously. This is because without the checksum there is no check
on the basic integrity of the transferred data, and corrupted data may
cause problems in both the printer and the remote computer.
