The RoboScan Pro 918 has 5 fuses. The main fuse is located in the power inlet and may be replaced without opening
the fixture. Note: The main fuse may need to be replaced with one of another value when rewiring the fixture for oper-
ation at a different AC voltage. The fuses for each of the 3 low-voltage power supplies are located on the printed circuit
board. If one of the circuit board LEDs does not light, one of these fuses may be blown. To replace:
1. Access the printed circuit board as described above.
2. Locate and replace the defective fuse with a time-delay fuse of the same rating. Fuse locations are shown
on the PCB layout diagram and their values are listed in the specifications.
The fifth fuse is located on the mains filter and power protection circuit board, located between the ballast and the AC
power inlet. If this fuse is blown there will be no power to the transformer and the fixture will appear dead, but there
will still be mains voltage on the ballast. To replace the fuse:
1. Make sure the RoboScan Pro 918 is isolated from AC power. Access the mains filter circuit board fuse as
described above.
2. Remove the fuse with tweezers or a similar tool. Replace only with a special fast-acting fuse of the
same rating (P/N 05021010).
3. Replace the ballast/transformer cover.

This procedure reverses the signal polarity of pins 2 and 3 on the
XLR connectors so that the fixture can be connected directly to
Martin RS-485 protocol devices. Optionally, a phase-reversing
cable may be used.
1. Access the printed circuit board as described above.
2. Position the jumpers on PL 233 and PL 234 for the desired XLR pin-out as shown.

The latest software for the RoboScan Pro 918 is available from your Martin dealer and the Martin Professional web
site. Please read the update notes bundled with the software. Update software is uploaded to the RoboScan Pro 918
using a Martin uploader such as the MBPP1.
N o r m a l u p l o a d
Connect the uploader to the fixture just like a controller. Under normal conditions, software can be installed from a
remote location - there is no need to set the RoboScan Pro 918 to boot mode. Please refer to the uploader manual for
further instructions.

If the data is corrupted during transmission, a check-sum error (
CSER
) will occur and after 15 seconds the fixture will
automatically switch to boot mode (
UPLd
) and be ready for a boot-mode upload as described below and in the
uploader manual.
If a software upload to the RoboScan Pro 918 is interrupted, the fixture must be powered off for at least 10 seconds
before a new upload can be attempted. When powered on, a check-sum error will occur and it will automatically go
into boot mode, ready for a second upload attempt. Select boot mode upload on the uploader.
If there is no functional software in memory, the fixture must be set to boot mode manually before starting the upload.
If the control panel works, select
UPLd
from the
SPEC
menu and confirm when
SURE
is displayed by pressing
[ENTER].
If the control panel does not work, boot mode can be engaged by moving jumper PL121 on the main circuit board to
pins 1 and 2 as follows.
1. Access the printed circuit board as described above.
