The pin assignments for Crescat-QM, CAT5, CAT5E, and CAT 6 wiring are based
on the EIA/TIA 568B RJ-45 Jack standard.
RJ-45 QuickMedia Connector
Pin 1
To determine which pin is number 1, hold the cable so that the end of the eight-pin
modular jack is facing you, with the clip down and the copper side up. When looking
down at the copper connections, pin 1 is on the far right. The following table lists the
pin assignments on the RJ-45 connector.

for making Cresnet connections.
Identity Code
All equipment and user interfaces within the network require 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 25 for details of the SIMPL
Windows procedure.
Refer to the note on page 68 for a
definition of Viewport.
The Net ID of the MD7x2 has been factory set to
08
. The Net IDs of multiple
MD7x2s 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 68. 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 2-Series control system that require a single unit
be the only network device connected to the control system.
Method B
(Touch Settable ID or TSID), which begins on page 18, 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
