5.16 Connection of the OIC card to the DAU (for I.SITE II - connec-

tion)

The radio coverage of the DAU can be extended by connecting the I. SITE II. The I.SITE II

is a deported emitter which emits the same POCSAG notification synchronously with the

DAU. In order for the I.SITE II to receive data from the DAU, the OIC card must be mounted

in the DAU. The I.SITE II receives the emitter control and modulation data from the OIC

card via a potential free serial RS422 connection.

Note: The I.SITE II emitter can be deported by a maximum of 1200m cable length (Twisted

0.6mm

Cu-wire).

The OIC-card can be mounted in the free slot to the right beside the SC card or S-Com

card.

1. Device is switched off, power plug or battery is removed.

2. Unscrew and remove the cover plate beside the SC card or the wide cover plate beside

the S-Com card (if assembled).

3. Unscrew SC card and completely pull out.

4. Remove wide ribbon cable from the SC card which leads to the TRx module. Then plug

in the new ribbon cable provided with the OIC card into the SC-card and connect to the

OIC card (see figure below).

5. Assemble SC card and OIC card with one another (if necessary disassemble the right

cover plates to simplify assembly). The long part of the wide ribbon cable should there-

by lead to the rear towards the interface print of the TRx module, similarly to the old

ribbon cable. Sometimes it is necessary to remove the top cover of the ITC2100-NA to

simplify assembly.
