3.3.2.2 Two Unit Operation
A better solution than using one product is the use of two units connected together via a
cable. When one unit receives the incoming signal, it buffers the message, turns on the other
unit’s transmitter and commences the transmission. The same applies in the opposite
direction. There will be a time delay with this set-up, as the receiver has to detect the carrier
and then turn on the other unit's transmitter. The advantages are; the receivers in both
directions are always active and so either direction may initiate a call, and different antennas
for each radio can be used to suite the application and provide additional isolation.
3.4 MEMORY EXPANSION & PROGRAMMING PORT
JP5 is the memory expansion and processor programming port. This port is used during
production to download the firmware into the processor’s flash memory. Once programmed
the 3 jumpers are installed linking
1-2, 3-4 & 5-6 for normal operation.
Should the memory expansion card be required, the links are removed and the card is
plugged in their place.
