DataPage MK2 (USA) Desktop UHF Radio Paging System
the internal extensions can select this line port either by way of a pre programmed feature button or dialing a
discreet code. This line port system will work with all exchanges which will accept that the line port is active
from the correct line voltage being present. This system will not work where the exchange requires the line port
to receive digital dial tones .
Refer to Section 2: "Telephone Interface" for more comprehensive information.
4) NDPSUSA as per the NDPUSA but supplied with an RS232 serial port
5) NDPMFSUSA as per the NDPMFUSA but supplied with an RS232 serial port
6) NDPLPSUSA as per the NDPLPUSA but supplied with an RS232 serial port
NOTE! Serial ports can be ordered with various communications and set up protocols! Check before
quoting or ordering!
Some major points to remember when installing the equipment:-
♦ Never install aerials near to overhead power lines or adjacent to telephone or public address or data
communication lines.
♦ Avoid, wherever possible, running aerial feeder cables alongside other cables e.g.: telephone and mains.
♦ Avoid mounting the transmitter in the immediate vicinity of telephones, exchanges or computer equipment. A
few feet can make the world of difference in avoiding interference from the radio frequency generated by the
transmitter.
Optional RS232 Serial Port
This can be ordered as an option to enable the unit to be driven by PC's, nurse call systems, fire, security,
access control and monitoring systems and many other applications. To ensure that the unit comes suitably
equipped for your application you will need to confirm the baud rate and port protocol as well as the
communications protocol required to interface with your host equipment. (for more technical information refer to
Appendix A)
System Operation
1) Connect the 90 degree aerial to the BNC connector (bayonet twist lock) located at the side of the transmitter.
Slide the plastic cover over the connector, engaging the two lugs into the corresponding recesses in the side of
the case. This will maintain the aerial in an upright position, which is important for optimizing the range of the
transmitter. See Figure 1.
2) Connect the AC adaptor power lead to the socket located at the far right hand rear corner of the base station.
See Figure 2. Ensure the two jack plugs are fitted (DC1 and DC2), even if they are not wired to a switch, as
removal will trigger the unit when it is first powered up (unless they have been programmed out - see Program
Parameters, section 2: Inputs)
Important note: Only use the AC adaptor supplied with your system! The use of non-approved adaptors will
invalidate all warranty and service.
3) Check that the pagers have their batteries inserted and that they are turned on (refer to the individual pager
instruction manuals supplied with the system).
