RECEIVER RX-400 - Quick guide
Each 'MINDA' TX-400 receiver can display two status indications from up to four different
transmitter units, coded 1-4 and all operating with the same group code. Pressing the RED button
on a 'key-fob' style transmitter should light the Red LED on the receiver, whilst the BLACK one
lights the Green LED.
'BEEP' mode is selected by moving the On/Off switch in the direction away from the eight LED's,
and 'SILENT' mode is selected by moving the On/Off switch towards the eight LED's.
Briefly pressing the 'Reset' button will cancel any audible alert, initiate a 'lamp-test' and extinguish
any LED's that may have been illuminated prior to resetting.
Additional alerts provided
1. A Transmitter Low-Battery alert causes the appropriate LED indicator on the receiver to 'blink'
out briefly about once per second.
2. A Receiver jamming alert will cause a series of audible 'beeps' to be generated. If this occurs
you should move to an interference-free location and as soon as the interference clears the
'beeps' will cease.
TRANSMISSION RANGE.
When using the 'MINDA' system over a line-of-sight path you are likely to obtain a working
distance in excess of 100 yards, whereas in a busy street, hotel or station the range will be
noticeably less.
It is recommended that, before using a 'MINDA' system in a 'live' operational situation, you carry
out a few tests in the location(s) of interest to confirm consistent and reliable operation.
'MINDA' SYSTEM - FULL USER'S GUIDE
GENERAL.
A system, comprising transmitter(s) and receiver, will have been supplied programmed with a
specific 'Group Identity' out of the 255 possible codes available. This is set during production to
'94' (hex.) unless an alternative group code identity has been requested by a particular customer.
Individual transmitters will also have been programmed with a Unit Identity (1,2,3 or 4), which will
be shown on the label on the back of the case. The micro-processor controlled receiver will only
respond to signals from those transmitters sending the same 'group-code' identity that it has been
pre-programmed to accept. This capability minimizes the risk of interference between similar
systems that happen to be operating within radio range of one another.
'MINDA' transmitter and receiver units can be reprogrammed to different codes if required, but
this operation requires the use of workshop facilities including a PC, software and a special
interface unit. Contact your supplier for more details.
