2. Continue to press the channel Switch until the required function is indicated by
the LED/s.
3. Press and hold the channel switch to record the new setting.

Connecting Control Input
Where DMX control is to be used, the input signal to the HPC should conform to the
specified standard for DMX and RDM. Plug the DMX-512 signal to the "DMX IN" socket.
The DMX signal may be daisy-chained to the next DMX receiver via the LOOP
connector.
The SIGNAL LED indicates the presence of control data.
The DMX-512 input is protected against extreme over-voltages across any input pins
and from any input to chassis. The "terminating" resistor is not protected against over-
voltages.
Where the Ethernet option is fitted, plug the Ethernet data into the front panel
connector. The source of control for DMX and RDM must be manually selected via the
menu between the front panel DMX connector and the Ethernet connector – refer to
Section 5.1.6.
4.4.1
Changing the DMX Address
The DMX-512 address is the DMX-512 channel number that will be used to control HPC
dimmer channel 1. HPC dimmer channels 2 and up are controlled from the next DMX-
512 channel upward.
To change the DMX-512 address:
1. At the root menu adjust the displayed value using the + and – buttons until it
matches the required start channel.
2. Press MENU/ to confirm.
4.4.2
DMX Termination
In any DMX-512 system the signal should be terminated at the last dimmer or receiver
in the chain - the HPC can provide this function. Refer to Section 5.1.4.
The TERM LED indicates when the Termination function is active. Note that when
termination is active no signal is present at the LOOP connector.
