For RC1740 you can tune the output power from +15 dBm to typ -10 dBm. TX current will be reduced if ourtput power is reduced. At 0 dBm it will be typ 35 mA.

- [RC232] I discover that when I start the system, CONFIG pin is low and UART is not initialised. I think it is a mistake and can create some problems. Can you comfirm?
- [RC232] “I have problem to wake up RS1240 from sleep mode, in fact I can’t wake it up at all. According to documentation, config pin should be asserted when going to sleep mode, and then positive edge should wake ip module This is code I use: Config Portd.3 = Output : Modem_config Alias Portd.3 Modem_config = 1 ‘ ———— PUT MODEM IN SLEEP MODE Modem_config = 0 ‘ Assert Config pin Waitms 5 ‘ MAX Time from CONFIG pin is set low until prompt (“”>””) Print “”Z””; ‘ Goto SLEEP mode . . . Sub Send_packet Modem_config = 1 ‘ Wake up form SLEEP mode Waitms 60 ‘ Wait 60 ms to get out from sleep mode Print “”X””; ‘ Goto idle mode Led_tx = 1 Printbin Paket_start Printbin Data_packet Led_tx = 0 Modem_config = 0 ‘ Assert Config PIN Waitms 5 ‘ MAX Time from CONFIG pin is set low until prompt (“”>””) Print “”Z””; ‘ SLEEP mode End Sub But, module stuck in sleep mode, and dont send enything. When I comment all lines regarding sleep mode, module work fine. Where I’m wrong? I should deliver device this week, and this is only problem I have to resolve. “
- [RC232] The MAX input power is 10dBm. What appen if the module receive a greater power? Just the signal make worse or the module could be damaged? In case could you suggest a protection circuit?
