Since most older radios have old style TTL or RS-232 connections for this channel and most computers have abandoned these old style serial ports, we need to add a USB-to-Serial adapter to the computer. This is usually a simple piece of hardware (UART) accompanied by a Mac software driver that allows the application to "see" the radio connected to this device. The device may also include level converters to convert the RS-232 to the TTL level required by the (older) radio and sometimes DTR and RTS lines to also let the computer key the radio's PTT and CW lines.
This IC-7700 version was released in April 2011. It incorporates redesigned PA200W and FILTER Units. The new PA200W uses a single STMicroelectronicsSTAC2942B dual MOSFET power device in its output stage. The serial number prefix begins with "1" e.g. 1201234 (US/Canada), 1301234 (EU), 1701234 (UK).

The previous serial number ranges begin with "0" e.g. 0201234 (US/Canada), 0301234 (EU), 0701234 (UK), and have the earlier PA200W (2 X MRF150) and FILTER Units. 2ff7e9595c
