6 FLP4 commands

FLP stands for Flashlink Protocol. The current revision of this protocol is 4, hence FLP4. This

specification is available from Nevion Support.

The following FLP4 block commands are used in the monitoring and control of the module.

 ablk

 pwr

6.1 ablk

The „ablk‟ blocks correspond to the physical audio ports as follows.

Block no.

Audio Port

A/D stereo input 1

A/D stereo input 2

A/D stereo input 3

A/D stereo input 4

AES reference input

Blocks 0 to 3 report and accept the „lvl‟ keyword followed by the maximum input level in cBu

(dBu multiplied by 10).

i.e. ablk 0 lvl 240 cBu

Blocks 4 to 6 report input presence with the „freq‟ keyword followed by the received sample

frequency or 'los' or 'lol'. Absence of signal is reported with 'los' while 'lol' indicates an

unrecognized sample frequency.

i.e. ablk 4 input freq 44 kHz

6.2 pwr

The „pwr‟ blocks from 0 to 4 list the levels of the power supplies as measured by the

microcontroller.

 0 is the frame +5V

 1 is analogue +4.8V

 2 is the frame +15V

 3 is the frame -15V

 4 is digital +3.3V

The frame supplies are measured after the module fuses and filtering.

6.3 On-site re-programming

The module may be re-programmed on site with a GYDA Multicon system controller.

Firmware will be provided by Nevion support when necessary.
