1.5 Control LEDs
The OEM-MOPA light source is equipped with three LEDs on the front side. They are intended for visual
indication of the device current status. Refer to Table 1
for the most comprehensive explanation of the LEDs’
status.
Table 1. Statuses of control LEDs
LED Name
LED State
System status
“OUTPUT” *
No light
The optical output is off.
Flickering green
The optical output is starting (soft start).
Green
The optical output is on.
Yellow
SLD current limit reached
– SLD degradation; time to service.
“STATUS”
No light
No power. No active SLDs.
Flickering green
Temperature stabilization is in process.
Green
SLD temperature is stabilized at the pre-set level on all channels. The
optical output can be switched on. No errors detected.
Flickering red
The optical output and all controls are disabled once the interlock has
been actuated (correspondent terminals on the REMOTE port are
open circuited).
Interlock is only operable, if the correspondent option is computer
activated
(“
Configuration
” area in the SUPERLUM’s companion
software
– see Sec. 4.3 below).
Red
Common Error. Failure of the temperature controller.
“MODE”
No light
The unit is in manual operation. Remote control option is not activated
Green
The unit is in REMOTE port operation (manual operation is disabled)
Yellow
The unit is in computer remote operation (manual operation is
disabled). USB mode.
Flickering yellow
The unit is in computer remote operation (manual operation is
disabled). USB SERVICE mode.
*
– LED reflects the status of the combined optical output, i.e. all “active” SLD channels together (that user pre-selected in the companion software, or all
channels as factory preset). Failure of, at least, one of the channels will result in the failure status of the combined optical output.
1.6 Remote Control Features
Refer to the companion software for remote control of the OEM-MOPA light source from a PC (or laptop)
using a USB connection. The device is fitted with a USB virtual serial port located on the back side of the
device.
Short summary of the most relevant remote-control features (also those available with
SUPERLUM’s
companion software) are given in Table 2. See Sec. 4.2-4.4 of this document for more information on this
subject.
Table 2. Remote control features
USB (virtual COM port)
REMOTE port
- ON/OFF control of the optical output;
- Pre-selection of certain SLD-channels for ON/OFF
controlling;
- Monitoring of relevant driving parameters of SLD-
channels;
- Self-test option
– remote diagnostics feature;
- Enabling/disabling the option of analog remote
controlling via the REMOTE port (does not apply to the
interlock control). Activation of this option disables a
manual ON/OFF control of the optical output from the
front device panel;
- Controlling of optical performance.
The REMOTE port is operable only if the
correspondent option has been computer activated.
- ON/OFF control of the optical output by analog
remote signals;
- Monitoring of device statuses (e.g. on/off statuses of
the optical output, service status);
- Remote interlock control: interlock is actuated when
correspondent terminals on the REMOTE port are
open circuited.
- Interlock is only operable, if the correspondent
option is activated in the computer control software.
