Program on CD-ROM and SWITCH-MODEM a.k.a. switchbox RadioCom
In the following we are always talking about a SWITCH-MODEM. It is an ISAC (Integrated Special Application Chip) developed by BONITO. It is responsible for a number of functions performed by RadioCom. The complete circuit is housed in a small D-Sub 9-pin adapter. RadioCom control software operates with a 4 byte frequency data protocol. Please change the ICOM frequency data protocol to 4 bytes, too ( from 5 to 4 bytes), if necessary.
to computer serial port Presently, there are three different adapters available: IC-SWL receive only (RC-SWL receive only .... now replaced by RC-HAM ) RC-HAM receive and transmit The switch-modem IC-SWL is used by all ICOM-radios with CI-V/CT-17 , RS-232 , PCR-1000/100 and DRAKE. A standard serial cable is used to connect the switch-modem and the radio. The switch-modem RC-SWL/ RC-HAM is used by all other radios as well as ICOMs with CI-V but without CT-17 , however, it quires special adaptor cable. Please note that the MALE pins are not RS-232 compatible.
1. LOWE-HF 150 2. YAESU-FRG100 with CAT 3. ICOM-radios with CI-V (replaces CT-17 level converter) 4.Radios with standard serial port, and level converter, i.e. KENWOOD, AOR, NRD etc.... LOWE-HF 150 , YAESU-FRG 100 and ICOMs with CI-V can be connected without an extra level-converter. The RC-SWL/RC-HAM already includes the necessary electronic.
Pin - 5 = ground, GND Pin - 2 = RX from Computer Pin - 3 = TX from Computer Pin - 4 = LOWE-HF-150 to keypad-junction Pin - 6 = YAESU-FRG100 to CAT--Pin-#3 Pin - 6 = ICOM to CI-V bus
refers to RC-HAM switch modem only: Pin - 8 = to PTT switch Pin - 4 = to Kenwood to substitute IF-232C interface}
LOWE-HF-150 You need a 2-wire connection with a 3,5 mm mono-jack-plug to the keypad-junction of the LOWE-HF-150 RC-SWL LOWE-Keypad Pin-5 .........................GND...................... jack-plug-shank Pin-4 ............. Receiver controlling .......... jack-plug-head
YAESU-FRG100 / ICOM CI-V YAESU: requires a 6-pin-DIN Male Plug (please refer to the YAESU-handbook). ICOM: requires a 3.5 mm mono-jack-plug for the CI-V bus (please refer to the ICOM handbook).

Basically, any radio with a RS-232 data bus can be controlled by RadioCom. Please consult the manual of your radio for details, i.e. correct pin-connection. Usually the RX-signal from the computer (pin#2 of RC-SWL ) is not required by the radio. In principle, the basics are always the same ( see above = AOR up to Kenwood , almost identical):
