ian, Spanish, and Hebrew. The pages on which these safety messages appear are also
listed.
CAUTION !For V.24 installations, a V24/RS–232–C adapter
(12–27591–01) must be fitted between the adapter
cable and the extension cable, or between the
adapter cable and the modem, if the modem/eliminator
has any of the following:
•A signal with a DCE source on pin 18
•Signal quality implemented on pin 21
•Data Signal Rate Selector (DCE) on pin 23
Failure to comply with this could result in damage
to the interface module and modem or modem eliminator.
If you are not sure what signals the modem or modem
eliminator provides, contact Digital Field Service.
(Page 3–15)
CAUTION !The V.24 to RS–232–C adapter must be fitted between
the adapter cable (BC23V–02, BC19D–02, or BC19V–02)
and the extension cable if the modem/eliminator has:
•A signal with a DCE source on pin 18
•Signal quality implemented on pin 21
•Data Signal Rate Selector (DCE) on pin 23
Failure to comply with this could result in damage to the
interface module and modem or modem eliminator. If
you are not sure what signals the modem or modem
eliminator provides, contact Digital Field Service.

ATTENZIONE !Bij V.24–installaties moet er een V24/RS–232–C adapter
(12–27591–01) worden geïnstalleerd tussen de adapter–
kabel en het verlengsnoer of tussen de adapterkabel en
het modem, als het modem/de eliminator voldoet aan één
van de volgende voorwaarden:
•Een signaal met een DCE–bron op pen 18
•Signaalkwaliteit geïmplementeerd op pen 21
•Data Signal Rate Selector (DCE) op pen 23
Als aan geen van deze voorwaarden is voldoen, kan er
schade optreden aan de interface–module en het modem
of aan de modem–eliminator. Als u niet zeker weet
welke signalen het modem of de modem–eliminator
levert, neemt u contact op met Digital Field Service.

schade optreden aan de interface–module en het modem
of aan de modem–eliminator. Als u niet zeker weet
welke signalen het modem of de modem–eliminator
levert, neemt u contact op met Digital Field Service.

ACHTUNG !Bei V.24–Installation muß zwischen dem Adapterkabel
und dem Verlängerungskabelbzw. zwischen dem Adapter-
kabelund dem Modem ein Adapter V.24/RS232–C
(Best.Nr. 12–27591–01,
erhältlich über die Geschäftsstellen von Digital Equipment)
angebracht werden, wenn das Modem/Nullmodem
folgende Bedingungen erfüllt:
•Signal mit DCE–Source an Stift 18
•Signalqualität an Stift 21
•Data Signal Rate Selector (DCE) an Stift 23
Wenn Sie diese Richtlinien nicht einhalten, können das
Schnittstellenmodul und das Modem oder das Nullmodem
beschädigt werden. Wenn Sie nicht wissen, mit welchen
Signalen das Modem oder das Nullmodem arbeitet, wen-
den Sie sich an den Field Service von Digital Equipment.

ATTENTION !Pour les installations V.24, un adaptateur
V24/RS–232–C (12–27591–01) doit relier le câble
adaptateur au câble d’extension, ou le câble
adaptateur au modem, si le modem ou le
simulateur de modem possède les caractéristiques
suivantes :
•un signal avec une source ETCD à la broche n18;
•un détecteur de qualité du signal à la broche n21;
•un sélecteur de débit binaire (ETCD) à la broche n23.
Le non–respect de cette directive peut endommager
le module et le modem ou simulateur de modem.
Veuillez communiquer avec Digital, si vous ne
connaissez pas les types de signaux transmis par votre
modem ou simulateur de modem.
