E.RS-232.This female DB-9 serial port is for interconnection between the GT1524 and a PC or custom remote control. See Appendix C for serial port commands.

F.Control/Status. This female DB-25 connector is used to interface parallel control and status to the GT1524. Control pins on this connector are used to perform functions via a momentary closure to ground. Each status pin on this connector shows the state of the function handled by the pin. Status pins are open collector outputs. When active, the output is pulled to ground; otherwise, the output is an open circuit. See Appendix B for control/status port pinout information.

G.Speaker. One 5W, 4–16Ωspeaker can be directly connected to the GT1524, eliminating the need for a power amplifier.

H.Telco Line. Connects to your telephone line source.

I.Telco Set. Connects to your telephone handset.

Operational Requirements

Equipment placement

The GT1524 is designed for mounting in a 19-inch equipment rack. (Do not block any of the ventilation holes.) With a desktop kit, the GT1524 can be modified for tabletop placement.

Telephone line requirements

The GT1524 operates on a standard analog telephone line and connects to the telephone system with a standard RJ-11C modular jack. If you do not have an RJ-11C jack where you want to install the GT1524, call your telephone company for installation.
