easyRadio Advanced

Postby radiomadeeasy » Mon Jan 14, 2013 3:58 pm

LPRS has taken development of its highly sucessful easyRadio even further by introducing to the market the new "Advanced" transmitters and transceivers. Not only is it easy to implement, but with narrow band operation and much improved immunity to interference much longer range can be achieved. Incorporating our unique easyRadio software protocol, easyRadio Advanced (eRA) modules extend on the simplicity of previous easyRadio (02) modules by remaining true to the original brief of reducing time to market by removing the complexity associated with the radio software development interface.

Among the innovative features on the easyRadio Advanced transmitters and transceivers are:

Transmitting range at test site 1.6 miles.
The ability to change the bandwidth of the radio from 150KHz down to 12.5KHz, which means narrow-band performance on a wide-band budget.
User configurable self-coding system enables interfacing to other raw data modules in
both FSK (FM) and ASK (AM) modulation.
Free flash firmware upgrade tools from LPRS, mean new updates/features can be quickly programmed by your engineer making a truly future proof solution.
Designed with back compatible pin configuration, current easyRadio 02 users can easily upgrade to easyRadio Advanced versions with a minimum of fuss.

Re: easyRadio Advanced - Datasheet v3.6

Postby awneil » Thu Feb 21, 2013 1:05 pm

On p6, under the 'Pin Description' table, easyRadio Advanced Datasheet v3.6 wrote:See Application Circuit (Figure 11) for typical connection to an RS232 port via MAX232 interface IC.

I see no "Figure 11" in the document, and nothing with a MAX232 in it

Thank you for pointing out the omitted diagram. Please click on the diagram attached. This shows a simple connection between easyRadio modules and a MAX232.

Thanks.

That just shows a 2-wire connection (RxD, TxD).

The table in the datasheet suggests that 'Busy Out' has "CTS function", and 'Host RDY' has "RTS function" - does that actually mean that 'Busy Out' can be wired (through the MAX232) to CTS on the RS232, and 'Host RDY' through to RTS :?:

You are right Awneil,'Busy Out' can be wired (through the MAX232) to CTS on the RS232, and 'Host RDY' through to RTS. To be specific,
Connect Radio module RTS to MAX 232 T2IN and radio module CTS to MAX 232 R2OUT on TTL side. And on MAX232 RS232 side , connect R2IN to RS232 RTS and T2 OUT to RS232 CTS. Hope this helps. Thanks
