Channel disable
When the dimmer is in normal operating mode (
“OK”
showing on the display), any
channel may be taken off-line by pressing its
SELECT
button. Pressing the button a
second time will bring that channel back on-line.
The
STATUS
LED will be on (red or green) for all active channels, and be off for all
disabled channels.
Any disabled channel(s) may still be selected and tested with the TEST function (see
section 4.1.9). Once the tests are complete and the dimmer is back in normal operating
mode, the channel(s) will resume their status prior to being tested.

Software update
The operating software of the HP dimmer may be updated via the front panel DMX
input connector. To achieve this requires the following:
•
HPTR or HPSC dimmer
•
HP download kit
•
IBM compatible Laptop or desktop computer
To update the software, perform the following:
1
Switch the dimmer power off.
2
Connect the computer serial/COM port to the DMX input of the dimmer, using the
download cable supplied in the download kit. Disconnect any DMX terminators.
3
Press and hold the
ENTER
button on the dimmer while turning on power to the
dimmer. The dimmer display will show
“LOAD”.
4
Release the
ENTER
button.
5
Run the update software as supplied with the download kit.
6
The dimmer will display
“DATA”
and the keypad LEDs will chase while the
information is transferred. This takes around 30 seconds.
When the download has completed the display will blank while the new software is
permanantly programmed into the dimmer memory. At the completion of the
programming the dimmer restarts.
The software update facility should be used with the following notes and cautions:
•
The dimmer must be Deep Cleared (refer section 4.2) after downloading new
operating software.
•
It is recommended that dimmer software not be updated during a tour/show season,
unless the installed software proves unsatisfactory for normal operation.
•
More than one dimmer may be updated at a time using normal DMX cables to link
the DMX Loop connector of the first dimmer to the input of the next, etc. In this
case steps 3 and 4 must be repeated for each dimmer, before proceeding to step 5.
•
Refer to the instructions supplied with the download kit for further details.
