Confirmation of power connection is by way of the red LED on the base of the transcoder console.
Confirmation of transmit is provided by way of the momentary green LED on the base of the transcoder
console.
Sending data in the correct format (see Technical Section, Calling Pagers) will invoke transmitted
messages to the relevant pagers.
Problems and Fault Finding.
1
Check and re-check the data cable connections. This, together with an incorrect
signalling format, result in more faults than any other problem.
2
Check that the communications Baud rate of the host equipment matches that of the
relevant RS232 port (see page 6 for settings).
3
Check that the pagers are at least 3 metres from the transmitter and aerial. Under certain
conditions it is possible to flood the pager receivers and corrupt the data received.
4
Check that the pagers have the battery installed with the correct polarity and are correctly
powered up.
5
Check that the red power LED on the base of the transcoder is lit. If not, remove the mains
cord set and check that mains is available at the supply outlet.
6
Check that the green LED lights for the duration of the transmission. If not, go back
to the data cabling and re-check the signal format.
7
Check that the aerial is correctly installed.
IMPORTANT: Isolate mains before removing cover. Internal access and adjustments strictly limited
to authorised service personnel only.
Optional Dry Contacts
This option must be specified at time of ordering, along with the pre-programmed messages required.
Warning! Voltages applied to any of these contacts will cause irreparable damage!
This unit can support up to 10 dry (volt-free) contacts on PL1, which, when shorted to Pin 7 (ground), will
send a pre-programmed message to a particular pager address (which could be a to an individual, a group
or all pager operatives at the same time). These messages are pre-programmed and can only be changed
by qualified service personnel. For pin out configuration, see page 6.
The trigger time required to send a message must be greater than 1 second.
Individual messages can be sent upon both changes of state with a maximum alphanumeric length of 80
characters or 20 numeric digits.
As a default, contacts are programmed as Normally Open (N/O), with a repeat transmission every two
minutes if still active.
Note: repeats are not available where contacts are programmed as Normally Closed (N/C).
