NOTE: All network wiring must consist of two twisted pairs. One twisted pair is

the +24V conductor and the GND conductor. The other twisted pair is the Y and Z

conductors.

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.

NOTE: For larger networks (i.e., greater than 28 network devices), it may become

necessary to add a Cresnet Hub/Repeater (CNXHUB) to maintain signal quality

throughout the network. Also, for networks with lengthy cable runs, it may be

necessary to add a Hub/Repeater after only 20 devices.

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 16 for details of

the SIMPL Windows procedure.

Refer to the note on page 20 for a

definition of Viewport.

The Net ID of the IVDS has been factory set to 45. The Net IDs of multiple IVDSs

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 20. 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 Net ID:

Method A (Cresnet address-settable ID), described on the following page, applies to

devices in a Cresnet system with a CNX control system or with a 2-Series control

system and requires that a single unit be the only network device connected to the

control system.

Method B (Touch Settable ID or TSID), which begins on page 10, applies to all

TSID-ready devices in a Cresnet system with 2-Series control system upgrade file

(CUZ) version 3.029 or later. TSID functionality makes it possible for the control

system to recognize a network device via its serial number, which is stored in the

device’s memory. This method does not require that any devices be disconnected
