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.
