Appendix F: Join Number Remapping (JNR)
Introduction
Join Number Remapping (JNR) is a programming concept that allows a Crestron
Isys touchpanel (aka TPS-Series panel) to use join numbers with values over 4000
(join numbers 4001 to 15999 and Reserved Join Numbers) by bringing them within
the range of the TPS touchpanel symbol, thereby increasing a touchpanel’s
functionality. Through JNR, a TPS-Series panel can make its internal functions
become accessible to a control system, can route screen touches to multiple control
systems, can route its internal feedback back to a control system, and can receive
feedback from remote locations. JNR provides the additional capability of managing
IP IDs in Ethernet applications where a touchpanel communicates with multiple
control systems that have been uploaded with the same program or different
programs.
With standard programming techniques, developers had access to only 4000 digital
and analog join numbers, 999 serial join numbers to the touchpanel, and 127 serial
join numbers from the touchpanel. With JNR, a programmer can access up to 16000
digital and analog join numbers, 999 serial join numbers to the touchpanel, and 127
serial join numbers from the touchpanel as well as allowing a control system to
access a touchpanel’s internal functions.
Join Number Remapping (JNR) allows the designer/programmer to load a very
simple JNR Routing Table to an Isys touchpanel, in effect, making the touchpanel
more powerful. Although logic is not permitted in the JNR Routing Table, the
available signal routing offers incredible flexibility when used in conjunction with
SIMPL Windows (version 2.03.18 and later) and Crestron VisionTools (VT Pro-e)
(version 2.3 and later). To utilize JNR, an Isys touchpanel must have TPS firmware
version 1.017 or later.
When using JNR, inputs to the touchpanel result in the touchpanel performing a
specific function. Additionally, the touchpanel is capable of providing output
commands serially (via RS-232), over Cresnet
®
, or over Ethernet. There are no
provisions for the touchpanel to act as an external signal router that is capable of
accepting commands from an external connection and passing them through
unchanged to another external connection (i.e. Cresnet to Ethernet, Ethernet to
Ethernet, Serial to Ethernet). Even though SIMPL Windows allows such signals to
be put into the JNR program, the signals will not function.. A JNR program can only
route signals internally within the touchpanel.
Specific examples of a use for JNR include a touchpanel button press/release that can
be sent to one or more destinations under program control. Also, a new JNR program
can direct a command from a touchpanel over Cresnet, Ethernet, or serial
communication and receive feedback from any or all destinations. In summary, JNR
allows:
• Touchpanel acts as a peripheral: Programming with JNR permits a single
Isys touchpanel to be a touchpanel for multiple control systems.
• Reserved join number enhancement: With JNR, the Isys touchpanel can
designate as many external join numbers as desired to control internal setup
features previously not controllable from a control system. As a result,
reserved join numbers can be integrated into a SIMPL program.
NOTE: Reserved join number enhancement can only be used on TPS touchpanels.
