Custom control (DB-25) option
A customer-supplied remote control or contact-closure switch can be programmed to
perform functions such as: mute on/off, system on, and system off. For pinouts, see
Remote connector pinout, page 26.
External control system
The XAP products are designed to function with external control systems. The
controller is connected to the XAP 800 RS-232 port. Via the E-bus network, all
networked XAP products can be accessed and controlled from that single point. The
controller can also be connected directly to the XAP TH2 RS-232 port.
Using an external controller, the XAP TH2 can be turned on or off; transmit
and receive audio can be muted; DTMF tones can be generated (see Serial
Commands, page 28); the XAP TH2’s binary address can be queried; telephone
interface can be renulled; input and output can be metered and muted; and ERL
and ERLE can be read. These commands are also available in the G-Ware software
which can communicates with the XAP TH2 via the RS-232 serial port, the E-bus
network, or directly.
Touch-tone dialing
Through the expansion bus (and serial commands), the XAP TH2’s touch-tone
(DTMF) dialing capability can be accessed. This allows outbound calls to be initiated
by the XAP TH2 without requiring an external dialer or telephone set. This feature
continues to function after connection, enabling the user to issue tones for voice
mail/pager interaction. See Serial Commands on page 28.
