The required wire gauge should be chosen such that the resistance value is less than 
the value calculated in the resistance equation. Refer to the following table.

NOTE:  All Cresnet 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. 

Every equipment and user interface within the network requires a unique identity 
code (Net ID). These codes are recognized by a two-digit hexadecimal number 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 15 for 
details of the SIMPL Windows procedure.  

The Net ID of the C2N-VEQ4 has been factory set to 12. The Net IDs of multiple 
C2N-VEQ4s 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 26. If communication 
cannot be established, refer to the “Troubleshooting Communications” section in the 
respective Operations Guide for the control system.  

There are two different methods—Method A or Method B—for setting the  
C2N-VEQ4 Net IDs:  

Method A (Cresnet address-settable ID), described on page 9, applies to  
C2N-VEQ4s in a Cresnet system with a CNX control system or with a 2-Series 
control system upgrade file (CUZ) version prior to 3.008, but can be used with later 
versions of firmware and requires that a single unit be the only network device 
connected to the control system.  

Method B (Touch Settable IDs), which begins on page 9, applies to C2N-VEQ4s in a 
Cresnet system with 2-Series control system upgrade file (CUZ) version 3.029 or 
later. These upgrades enable Touch Settable ID (TSID) functionality, which makes it
