Crestron e-control Database Manager SW-DBM

21 •• Server Configuration In Depth Installation & Reference Guide — DOC. 5823

A “signal block” is a software

construct defined in the server

which communicates with

Intersystem Communications

(XSIG) symbols in the SIMPL

program running in your control

system.

The Signal Blocks tab (see below) displays a list of defined signal blocks. Two types

of signal blocks are available with an SW-DBM license:

Custom Scroller for interactive display and maintenance of an arbitrary

database table.

Standard Scroller a subset of the above; for interactive display of up to two

fields from a database table; typically used in support of a

separately licensed server component (such as SW-EMAIL)

(especially when not also licensed for SW-DBM);

conforms to SIMPL symbol Receive e-Mail.

Without an SW-DBM license, Standard Scroller signal blocks cannot be directly

enabled via a signal from a control system. In that case, they are only useful when

attached to another type of signal block designed to control scrollers. Examples of

such controlling signal blocks include, among others, the e-Mailer and e-Mailbox

signal blocks provided with an SW-EMAIL license. Such signal blocks can use

scrollers in support of their primary function. For example, an e-Mailer (e-mail

sender) can use scrollers to display an address book and prepared messages; an

e-Mailbox (e-mail receiver) can use them to display an IN box and a message. When

attached to a controlling signal block, a scroller is enabled automatically when the

controller is enabled.

With an SW-DBM license, a Standard Scroller can be enabled directly, and so can be

used on its own whenever the full functionality of a Custom Scroller is not called for.

Standard Scroller signal blocks are simpler, involving far fewer signals and options.

Their signal configuration is static and designed to interface with the included

Standard Scroller SIMPL Windows macro. (If you use a Custom Scroller, you

cannot use the macro.)

Specific differences between the two types of scroller signal blocks are summarized

in below:

Standard scroller options

no license required

Custom scroller options
