2. INSTALLATION STEPS

(i) Preliminary

Check the mains voltage shown on the rear panel.

Check the paperwork accompanying the Telex Unit to ensure that,

(a) the serial number corresponds

(b) the answerback is correct

No attempt should be made to install a Telex Unit if an error is

suspected.

(ii) Host Cable

It is the responsibility of the installer to provide the connecting cable

between the Telex Unit and the Host, including any monitor printer.

Two D-type connectors are required for connection to the Telex Unit.

If the printer connection is not being used, the D-Type Connector

Cover provided must be left fitted.

Select a position for the Telex Unit that is within cable reach of the

mains supply, host equipment, telex line termination and standby

teleprinter (if installed). The mains lead and telex connections

provided with the Telex Unit are approximately 2 meters long. The

chosen site should be secure, dry and avoid exposure to excessive

heat from equipment, room heating devices or direct sunlight. The

front panel should be visible so that the LED displays can be

observed during system operation.

Connect the Telex Unit as follows: -

(a) Insert Host connecting cable (25 - pin male D-type connector) and

(optional) monitor printer connecting cable (9 - pin female D-type

connector) into the mating connectors at the rear of the Telex Unit.

Connect the other ends of these cables to the Host and monitor

printer.

(b) Make connections to the telex line and standby teleprinter (if

installed) via the line plug and teleprinter socket (if installed). Refer to
