Ethernet Interface and Wiring
Ethernet Communication Port to vsmStudio
Port de communication Ethernet vers vsmStudio
Cette interface est utilisée comme port de communication Ethernet vers vsmStudio. Il est entendu que pour un fonctionnement correct, chaque LBP est connectée à un switch Ethernet dont le port individuel est réglé sur "Auto-négociation".
Pin | Signal | Color of a standard TIA-568A-shielded twisted pair patch cable (CAT5 or higher) | Scheme |
|---|---|---|---|
1 | TX+ | white/green |
|
2 | TX- | green | |
3 | RX+ | white/orange | |
4 | NC | blue | |
5 | NC | white/blue | |
6 | RX- | orange | |
7 | NC | white/brown | |
8 | NC | brown |
Notice for wiring:
- NC: No connection; does not connect to any signal or supply.
- Only use shielded CAT5 (or higher standard) -specified networkable. Refer to TIA-568A or TIA-568B for wiring.
- Do not use cable-traces longer than 100m (328ft) between the device and network-switch for 100BASE-T communication.
- Make sure to do standard wiring and use shielded RJ45-plugs for shielded cable on both ends of the line.
(EN) Warning
It is mandatory, that copper based Ethernet connections (CAT 5, RJ45) are led inside a building to the third party-device-ethernet-switch . If the Ethernet connection needs to be led outside a building it is mandatory to use a optical fiber. Use a converter to optical fiber and connect it in a short way (inside the building) to the device.
(F) Avertissement
Il est obligatoire que les connexions Ethernet à base de cuivre (CAT 5 ou une norme supérieure, RJ45) soient installées à l'intérieur d'un bâtiment jusqu'au prochain switch Ethernet. Si la connexion Ethernet doit être dirigée à l'extérieur d'un bâtiment, utilisez un convertisseur en fibre optique et une connexion courte (à l'intérieur du bâtiment) à l'appareil.
GPIO Connector (On front side of the device)
GPI/O-Interface
Connectors for the GPI/O interface: 8-Pin connector locked with two screws (MC 1,5/ 8-STF-3,81). 16 pieces of connectors are delivered with each device. See Connector Pin-outs for wiring details.
GPI - General Purpose Input
Grounding the input pin will 'set' the device. Supplying a DC voltage, it needs to be lower than 2.6 V DC to 'set' the device. Make sure not to supply any same ground external DC-voltage exceeding 12V.
The open-circuit-voltage of the inputs is approximately 3,8V. The external current for short-circuiting the input is limited down to max 8mA.
All inputs share the same signal ground potential. Make sure not to supply any positive voltage to the ground potential.
The built-in GPI inputs follow PS1 (electrical power source class1).
The GPI input will not allow power to exceed 1W by the device itself.
Open circuit voltage GPI input: approx. 3,8V DC, max. 5V DC
Short circuit current GPI input: approx. 8mA
Loaded circuit current with externally 12V (PS1) supplied: approx. 30mA
(EN) Warning
It is understood that if supplying any external voltage (DC only) to the GPI input
- it is never to exceed 12V DC rms and must also follow the PS1-rules (b-IEC 62368-1) to never source more than 15W
- check polarity if external DC-voltage is supplied
- always connect GPI input-ground to external supply-ground
- never apply any AC-voltage to the GPI inputs
(F) Avertissement
Il est entendu que si vous fournissez une tension externe (DC uniquement) à l’entrée GPI
- Il ne doit jamais dépasser 12V DC rms (valeur efficace) et doit également suivre les règles PS1 (norme b-IEC 62368-1) pour ne jamais fournir plus de 15W
- Vérifiez la polarité si une tension continue (DC) externe est fournie
- Connectez toujours la masse de l'entrée GPI à la masse de l'alimentation externe
- N’appliquez jamais de tension alternative (AC) aux entrées GPI
GPO - General Purpose Output
The GPO "outputs" are dry relay contacts. They are internally not connected to any supply or ground.
Les GPO « sorties » sont des contacts de relais secs. Ils ne sont connectés en interne à aucun approvisionnement ou terre.
(EN) Warning
The relay outputs are primarily designed for low level voltage (up to 30V DC rms / 30V AC rms) that meet the following LPS requirements for the external circuit (LPS: Limited Power Source, specified in IEC 60950 and IEC 62368 safety standard):
- DC-Voltage: lower or at a maximum of 30V DC rms
- AC-Voltage: lower or at a maximum of 30V AC rms
- Maximum short circuit current of 7A
- Maximum nominal rating of 100 VA
- Maximum nominal current of 5A
- Maximal nominal power of 5A multiplied by supplied voltage needs to be < 100 VA
For safety reasons while using "higher current" make sure the current does not exceed the maximum current permitted for each relay (maximum 7 A per relay).
(F) Avertissement
Les sorties relais sont principalement conçues pour des tensions de faible niveau (jusqu'à 30V DC rms / 30V AC rms) qui répondent aux exigences LPS suivantes pour le circuit externe (LPS : Limited Power Source, spécifié dans la norme de sécurité IEC 60950 et IEC 62368) :
- Tension DC : inférieure ou égale à 30V DC rms maximum
Tension AC : inférieure ou égale à 30V AC rms maximum
- Courant de court-circuit maximal de 7A
- Puissance nominale maximale de 100 VA
- Courant nominal maximal de 5A
- La puissance nominale maximale de 5A multipliée par la tension fournie doit être < 100 VA
Pour des raisons de sécurité, lorsque vous utilisez un "courant plus élevé", assurez-vous que le courant ne dépasse pas le courant maximal autorisé pour chaque relais (maximum 7 A par relais).
High level signals and low level signals should not be run together on the same GPIO.
Les signaux de haut niveau et les signaux de bas niveau ne doivent pas être exécutés ensemble sur le même GPIO.
Professional broadcast equipment mostly uses 5 V up to 24 V DC with a maximum current of 500 mA.
Due to physical properties the usage of higher voltage and higher current causes more abrasion within the relays. This may result higher transient resistance between the switching contacts.
Once used with up to 30V and up to 7A per relay, the GPO output should not be used (in another application) with voltage below 5V and current below 100mA, to avoid the incorrect interpretation of some switching conditions.
En raison des propriétés physiques, l’utilisation d’une tension plus élevée et d’un courant plus élevé provoque plus d’abrasion dans les relais. Cela peut entraîner une résistance transitoire plus élevée entre les contacts de commutation.
Une fois utilisée avec jusqu’à 30V et jusqu’à 7A par relais, la sortie GPO ne doit pas être utilisée (dans une autre application) avec une tension inférieure à 5V et un courant inférieur à 100mA, pour éviter l’interprétation incorrecte de certaines conditions de commutation.
Connector Pin-outs
Get Ready for Operation
If all GPI-connectors are connected, the total depth of the General Purpose Interface will increase up to 140mm. Each General Purpose Interface comes enclosed with a cable-lacing bar which can be mounted to the front cover for cable management of in- and output cables. If the bracket is mounted, the complete depth of the GPI-unit will be increased by another 61mm.
All Lawo devices will be shipped with DHCP enabled network configuration. If you don't have a DHCP network ask your administrator for static network settings and edit the "Network" section if required.
Do the following settings in VSM Discover: 
Press the "Apply" button if you are sure you have entered the settings correctly. The device will automatically perform a reboot to apply the network configuration.
To connect a device to vsmStudio enter the IP Address of Server 1 – 6 (depending on how many vsmStudio servers are part of the cluster) in the "Application" section. This connection will also be used for any future firmware updates.
The Location and Comment fields in the "Misc" section are to set to easily locate the device in your environment.
Additional read-only status and device information from vsmDiscover:
In vsmStudio, create the respective GPIs and GPOs that shall be associated with the hardware box.
Execute "regedit.exe" as Administrator on your vsmStudio server to configure the device and find the vsmStudio registry key:
HKEY_...\...\...\VirtualStudioManager\vsmStudio\Registered Devices
Allocate the MAC Address of the device in the "Registered Devices" list and use the Application Key (MAC Address with \[001\]) to enter your GPIO input and output-offsets.
To allocate the GPI and GPO ranges, select the “Base-Inputs/Base-Outputs” registry setting by double click on the respective key.
Change the “Base” setting to Decimal, then modify the “Value data” to match the desired start GPI or GPO number within your vsmStudio configuration. Once everything has been entered correctly, proceed with "OK", then reboot the device by un-/plugging the power cable. 
Native Ember+ Interface
Firmware version 2.35 or higher is required to use the provided native Ember+ Interface for digital GPI/O's. As long as the device has a valid connection to a vsmStudio, the Ember+ Interface is read only. The ports are represented as a One-To-N Matrix , where the matrix outputs are used as the device GPI/O ports and the matrix input is the connect/disconnect signal. Use TCP Port 9000 for the Ember+ connection.
