Remote Control
Extended Front Panel Control
The front panel of the TW7000 can be removed from the body of the
transceiver and replaced with a line driver panel (TW7000E). This
variation of the radio is used to remotely control operations from dis-
tances up to 50 feet.
FSK and ISDN Remote Control
DWC offers two separate remote control heads. The TW7201F and
the TW7201I can be used to control the transceiver from longer dis-
tances. Both control heads require that modem interface boards
(7000RF or 7000RI) be installed inside the transceiver. The TW7201F
uses FSK and can be used for long-range remote requirements; the
TW7201I uses ISDN and is used for real-time control up to 2 km.
These modem-based remote control units are connected to the
TW7000 via the remote connector on the back panel. This connector
is a D-submini socket with 9 pins.
For a complete description of each of these pins, refer to the
TW7201F FSK Remote Control Head Technical Manual (TW7201F-
MS) or the TW7201I ISDN Remote Control Head Technical Manual
(TW7201I-MS). The TW7000 HF Transceiver Technical Manual
(TW7000-MS) also describes these interconnects.
