DataPage MK2 (USA) Desktop UHF Radio Paging System
Telephone Interface (models NDPMFUSA and NDPLPUSA only)
Overview
IMPORTANT! This unit must not under any circumstances be connected direct to the public telephone network.
It is only intended for indirect connection to an in-house telephone exchange. Any attempt to operate the unit
other than as intended will invalidate all equipment warranties and may result in damage to the equipment, the
telephone network or both.
The Scope digital paging interface can be used to transmit text or numeric messages from any telephone
connected to your exchange, direct to the pocket of the individual being paged. There are two types of interface
available, these cover all types of hybrid and PBX systems with DTMF capability. These can be supplied in two
basic configurations:
1) ----LP. This interface connects to an external line port, it is supplied with a 50 volt supply to provide the
required voltage to the line port. This unit will work with any telephone system that can send DTMF to the
assigned port, without receiving a dial tone.
2) ----MF. This interface is only intended for use with systems dedicated to two wire ports. Access is gained by
dialing the extension number, the ringing will alert the system which will pick up the line. Use of this interface with
hybrids of any sort is not recommended and we cannot provide any support for such applications!
Both of these interfaces contain line voltage isolation devices. There is electrical isolation between the paging
logic and power supply, and the exchange side of the apparatus.
Installation:
For interface type LP, the A and B wire of the external line port are connected to the inner pair of wires on the
cable provided.
For the MF interface, use the lead provided to plug into a standard 2 wire extension socket as for any (SLT)
internal telephone.
Operation:
When the system leaves the factory, it will have been programmed with a default configuration which sets up the
system as follows:-
Number of pagers:

The system parameters can be changed and re-programmed via the keyboard, if required (see previous section:

Your system has been programmed to be fully functional before leaving the factory, there is no need to change
any settings if you are happy with the factory settings.
