C) Processor
1) Maximum delay time from input to output shall not be greater than one packet time
(approximately 22 mSec.).
2) A minimum DMX update rate of 40Hz shall be sustained under all conditions unless
specifically configured for a slower rate for the sake of compatibility with 3rd party DMX
devices.
D) Mechanical
1) The gateway faceplate shall be constructed of durable cast aluminum and mount in a
standard 1 gang backbox. Faceplates manufactured of plastic shall not be acceptable.
2) Gateways shall be provided in matte black powder coat finish.
3) The gateway shall be available in two versions
a) Wall mount gateway
1) The wall mount gateway shall support flush or surface mount applications
using a standard RACO 690 backbox or equivalent.
2) Dimensions shall not be more than 2.75” (70mm) wide x 4.5” (115mm)
High
3) Wall mount gateways shall not weigh more than.35 lbs (.16kgs)
b) Touring gateway
1) The touring gateway shall include a complete enclosure with Ethercon and
power connectors for wiring terminations
2) Dimensions shall not be more than 4.5” wide (115mm) x 3.5” (89mm) deep
x 6.34” (161mm) high (not including mounting hardware)
3) Touring gateways shall not weigh more than 2.5 lbs (1.1 kg).
E) Power
1) Power for the gateway shall be provided either over the Category 5 (or better) cable,
utilizing IEEE 802.3af compliant Power over Ethernet distribution equipment. Power
consumption shall not be greater than 5 watts.
2) The gateway electronics shall be electrically isolated from the power supplied over the
Catagory5 (or better) cable.
3) Power may be provided from any IEEE 802.3af compliant power-over Ethernet
distribution equipment, or by using conventional switches together with isolated in-line
power supplies as provided by gateway manufacturer.
F) Configuration
1) Each gateway on the network shall be individually configurable using Network
Configuration Editor (NCE), running on a network connected PC. The PC shall only be
required for configuration, and shall not be required for normal operation of the system.
2) Each DMX gateway shall control up to 512 DMX addresses. The specific DMX data
input or output by the gateway shall be freely configurable by the user. Duplicate
outputs of DMX lines (DMX splitter) and discrete outputs shall be fully supported.
