when communicating externally with the control system. The touchpanel “remaps”
the Device ID to the IP ID. Notice how the Device ID bundles the IP ID and IP
address for each Ethernet interface in the remap program.
NOTE: In some Crestron documentation, the device ID is called the “remap ID”.

ETHERNET
COMMUNICATION
NOTE: When an Ethernet touchpanel is functioning as a peripheral to several
control systems, additional setup is required. Normally, when a touchpanel comes
online, it issues an update request to its control system, clears all join number values,
and waits for the control system to resend all values. When the touchpanel is
attached to several control systems, the touchpanel may clear all values when it
should not. To prevent this from happening, type the command ALLCLEAR
SELECTIVE from the touchpanel console (the opposite is ALLCLEAR
NORMAL). The control system will tell the touchpanel to clear all digital and
analog join numbers within the range used by that control system. The SIMPL
Windows programmer must
be careful to use non-overlapping ranges of join
numbers for communicating with each control system.
Setting the IP Table in the Control System
Besides configuring the control system to communicate over Ethernet, it is assumed
that a C2ENET Ethernet Expansion Card is installed into the control system.
Ethernet devices that are addressed by the control system may have their IP IDs set
either in the SIMPL Windows program or through Crestron Toolbox using a PC.
Refer to “IP Tables” on page 61 for IP table setting details.
Setting the IP Table in the Isys Touchpanel
Furthermore, the IP ID in the controlled device's static master table must be set to the
IP address of the controlling system. Use Crestron Toolbox while communicating
over Cresnet or Ethernet to enter IP addresses. Over Cresnet, use Crestron Toolbox
to establish communication with the touchpanel and select Functions | IP Table
Setup…. The "IP Table" window appears. Refer to the Crestron Toolbox help file
for instructions using this feature. Add an entry for each device that communicates
with the touchpanel.
