In general, a radio system consists of a receiver and one or more transmitters. The
jumper selectable network id (0x0 to 0xb or 11 combinations) is used to define a
'matching identification' for each transmitter-receiver set. Thus, up to 11 wireless
networks (TeleMyo) can co-exist in the same vicinity without interference. Also, the
jumper selectable transmitter id (0x0 to 0x3 or 4 combinations) is used to identify a
specific transmitter when more than one transmitter is part of a TeleMyo network.
10.
Direct sequence spread spectrum radio module operating in the 2.4 GHz band. The
module is programmed to respond only to transmissions corresponding to its network id.
Data packets are sent/received using 'wireless network' protocols (802.11b).
11.
Nickel Metal Hydride rechargeable battery pack. Battery capacity is monitored by the
microcontroller and its status is reported periodically during radio transmissions to the
receiver.
12.
Battery charger circuit. Recharge cycle is 3 hours. Full charge is achieved in
approximately 2 hours and a trickle charge continues for the remaining 1 hour.
