Description
With this entity, the unit address for
flexcon protocol can be entered.
With this entity you can configure the
port used to communicate over
Fleconn TCP port
With this entity, password used to
enable the write protected entities
The following table lists the entities available for the IR HHC
communication on the System Config . Communication . IR HHC
screen.
Description
Disabling this entity (default) uses the
short login sequence of pressing only
the [ATTN] key.
Enabling this entity makes the
controller require the long login
sequence of four buttons being
pressed, [ATTN], [F1], [F2], and [F3].
With this entity you can enable the
IR interface, if it is turned off.
NOTE: In a few installations of Honeywell Enraf controllers, it
is reported that sunlight or any strong artificial light-
sources can "unlock" the infrared port the same way
as pressing the ATTN key on the Hand-Held
Controller. If this occurs, parameter values may acci-
dentally be changed.
Note that this is an EXTREMELY rare possibility.
NOTE: The Long Infrared access parameter enables or
disables an extended login sequence of characters
for the infrared communications port on the bezel of
the MSC-L. Using an extended login character
sequence raises the odds of a random pattern of
interference matching the correct login sequence to
astronomical levels.
