The GD-04P link cable
allows you to link David to a PC through a USB port and perform any desired configuration using GDLink software (supplied on a CD with the package). This fully-fledged configuration tool is especially suitable for those who perform frequent installations.
The GD-04D DTMF module
allows relay X and Y control by entering numeric codes (DTMF codes) on the telephone keypad during calls. (First call David’s tel. number and wait until the beep response, then enter the DTMF code and finally terminate the call.) The module can be installed by plugging it in to the appropriate digital bus.
