DRAKE Digital 4000 Series talk back panel 1RU
The 4000 Series II Control Panels comprise of a range of 1RU and 2RU by 19 inch rack mount units.
The standard connection of these panels is via CAT5 (RJ45) cabling to connect analogue audio and
RS422 data from the Control Panel to the PDE4628 Serial Communications RCU located in the Matrix.
Other connection methods are possible using twisted pair cable or a bi-directional digital link using
75ohm coaxial cable. This connects to the PDE4617 and PDE4616 Panel Communications RCUs
respectively, located in the Matrix.
There are also Extension Panels that are used to increase the number of buttons per panel or to add
level control facilities. These Extension Panels connect to the main Control Panel via screened ribbon
cable. A Custom Panel Interface is also available to remotely connect keys and displays from the main
Control Panel, so that a custom panel can be made to fit various size and shape constraints.
Details of the various panel connection pinouts are given in the section ‘Panel Connections’.
Note: If at any time a panel is removed from the system with its keys still active, the relevant
matrix crosspoints will remain in force until the panel is reconnected. Because of this fact, a
panel should only be removed after all of its keys have been de-selected.
Panels are DC powered by the 150/UNI and 151/UNI DIN 4 universal 110-240V mains adaptors.
