4 VBUS IN USB VBUS signal
5 HOTSYNC IN hotsnyc button - connected to +3.3V triggers a hotsync
6 n/c not connected
7 GND signal- and charge ground (connected to pin 1)
8 ID IN indentification for peripheral
9 VOUT OUT +3.2V supply output, 100mA max.
10 RxD IN RS-232 RxD signal
11 TxD OUT RS-232 TxD signal
12 DETECT IN peripheral detect - tied to ground by peripherals
13 CTS IN RS-232 CTS signal
14 RTS OUT RS-232 RTS signal
15 DTR OUT RS-232 DTR signal
16 CHARGE IN +5V charge supply input, 500-700mA min.

Notes

  • The VOUT pin supplies regulated 3.2V and a max. current of 100mA.
  • VOUT is equipped with an internal 250mA SMT soldered fuse! If it’s blown, it has to be replaced. So if you don’t own an SMT workplace and the appropriate skill, you better don’t fiddle with that pin. Let alone purchasing the fitting fuse (case 0603, Littlefuse).
  • The ID pin enables a peripheral device to identify itself. Depending on the resistance to GND, external devices can identify themselves as a USB cradle, an RS-232 cradle, a USB peripheral, an RS-232 peripheral or as a modem.
