NOTE:
All network wiring must consist of two twisted-pairs. One twisted pair is
the +24V conductor and the GND conductor and the other twisted pair is the Y
conductor and the Z conductor.
NOTE:
When daisy-chaining Cresnet units, strip the ends of the wires carefully to
avoid nicking the conductors. Twist together the ends of the wires that share a pin on
the network connector, and tin the twisted connection. Apply solder only to the ends
of the twisted wires. Avoid tinning too far up the wires or the end becomes brittle.
Insert the tinned connection into the Cresnet connector and tighten the retaining
screw. Repeat the procedure for the other three conductors.
Identity Code
Every equipment and user interface within the network requires a unique identity
code (Net ID). These codes are two-digit hexadecimal numbers from 03 to FE. The
Net ID of each unit must match an ID code specified in the SIMPL Windows
program. Refer to “Setting the Net ID in Device Settings” on page 22 for details of
the SIMPL Windows procedure.
Refer to the note on page 31 for a
definition of Viewport.
The Net ID of the CNX-PVID8x4 has been factory set to
41
. The Net IDs of
multiple CNX-PVID8x4s in the same system must be unique. Net IDs are changed
from a personal computer (PC) via the Crestron Viewport.
NOTE
: For detailed information on establishing communication between the PC and
control system, refer to “Communication Settings” on page 31. If communication
cannot be established, refer to the “Troubleshooting Communications” section in the
respective Operations Guide for the control system.
Complete the following steps to change the Net ID
1. Ensure that the CNX-PVID8x4 is the only device connected to the
control system.
2. Open the Crestron Viewport.
3. From the Viewport menu, select
Functions | Set Network ID
. The
software checks the baud rate and then opens the "Set Network ID"
window.
4. In the "Set Network ID" window, select the CNX-PVID8x4 from the
Current Network Devices
text window.
5. Select the new Net ID for the CNX-PVID8x4 from the
