Spectrum24 Terminal Setup
When the LWP.HEX is updated to 3.03, these values revert to the defaults. Be sure to check
them after LWP.HEX is installed. In particular, verify whether a BOOTP or DHCP server is
being used to allocate IP addresses. The default boot mode in version 3.03 is manual entry of
IP addresses. The terminal enters the configurator during the first terminal initialization after
the LWP.HEX upgrade, allowing you to check the settings.
Multiple Applications on the Same Terminal
The system files (from LWP.HEX) fill over 200 KB of the flash disk’s 1 MB. Current standard
applications such as STEP or TN clients require between 100 KB and 150 KB of flash disk.
This leaves ample space for installing more than one application on a single Series 384X.
Terminals have been configured to run as many as four applications, with a maximum of five
applications allowed.
Individual applications may require special terminal configurations that can only be set at
boot time, such as RAM disk size. The TN clients require configuring a minimum-size RAM
disk (<100 KB) because their limiting resource is program execution space. STEP, on the other
hand, uses the RAM disk to hold forms. Some STEP application implementations use forms
extensively and require a larger RAM disk (>100 KB). The application loaded last defines the
size of the RAM Disk for all applications on the flash disk.
Note: The system files contained in the LWP.HEX have the RAM disk
defined as 80 KB.
It is possible with multiple applications to have applications co-
existing on the terminal with conflicting memory requirements. If this
occurs, work out a compromise value that both applications can work
with before loading the files.
If multiple applications are installed on the Series 384X, a menu is presented during the
initialization process where you select the application to run for this session. Switching
between applications requires re-initializing the terminal and selecting an alternative
application when prompted. On warm boots, the terminal re-initializes and reenters the same
application that was selected before the re-initialization. On cold boots, if there are multiple
applications available, an application selection menu is presented.
