GENERAL DESCRIPTION

The DT-E70 Data Transmitting Unit is designed for exclusive use with the TOA EXES-6000 series

exchanges. Functions made available from this unit when used in conjunction with the DR-B61 Data

Receiving Unit and the HF-250M Intercom Station with a display include In/Out Annunciation and Calling

Party Indication capabilities. The unit can be used fro both desk-top and rack-mounted applications.

INSTALLATION

1. Rack mounting applications

Using the supplied brackets, mount the unit in the rack.

Note : The DT-E70 unit can not be mounted in the EX-610/620 exchanges. Mount it using the optional

CR-271N or CR-392N cabinet rack.

2. Desk top applications

Attach supplied rubber feet to holes (

2.5mm) in the bottom surface (four places).

1. Connect between the exchange and the data transmitting unit using the YR-806 cable (1m in length).

When the unit is placed on the EX-610 or 620 exchange, use the YR-802 cable (0.4m).

2. For connection between the exchange and the terminal box, use the YR-810 cable (for station) or the

YR-801 cable (for paging or tie-line unit).

3. When installing additional data transmitting units, use the YR-803 cable.

4. CN1 or CN2 connector may be used for connection because both connectors are internally parallel-

connected.

5. Use the 24V DC power supply having the current capacity of 0.2A per unit. If only one unit is used, the

power can be provided from the exchange's 24V output.

6. Use the shielded or twisted paired cable for connection between the data transmitting unit and the

DR-B61 data receiving unit.

7. Turn the power on for the data transmitting unit before the exchange. When turning the power off, first

set the exchange power switch to OFF.

8. Using the commercial 6-pin modular jack type rosette (4-conductor), connect HF-250M's modular plug

cord L1 and L2 to the BX-610 or BX-620 terminal box, and L3 and L4 to the optional YC-900 terminal

box.

Note : Remove the front and top panels to connect the EX-600 and the YR-806.
