	Excel 10 Q7752A SERIAL INTERFACE
SPECIFICATION DATA

GENERAL
The Excel 10 Q7752A Serial Interface or Serial LonTalk^� Adapter (SLTA) is a complete network interface unit that includes all of the required hardware and software to execute network operations for a twisted pair E-Bus network. Use the standard power supply or battery included for the SLTA with a portable operator terminal (PC) to perform network operations by connecting the SLTA via the SLTA connector cable to the E-Bus port on Excel 10 controllers or wall modules. For permanent installations, use a mounting bracket to wall mount the SLTA.

FEATURES

• Electronics Industry Association (EIA) standard RS-232C Interface.
• 1200 to 115,200 bits per second (bps) serial bit rate with autobaud detection.
• Uses E-Bus network protocol.
• E-Bus communicates through a 78 kilobit transformer coupled transceiver.
• Transformer-coupled communications interface offers much higher degree of common mode noise rejection while assuring DC isolation.
• Built-in power management and rechargeable battery.

DESCRIPTION
The Excel 10 Q7752A Serial Interface or Serial LonTalk^� Adapter (SLTA) is a complete network interface unit that includes all the required hardware and software to execute network operations for a twisted pair E-Bus network. Use the standard power supply or battery included for the SLTA with a portable operator terminal (PC) to perform network operations by connecting the SLTA via the SLTA connector cable to the E-Bus port on Excel 10 controllers or wall modules. For permanent installations, use a mounting bracket to wall mount the SLTA.

SPECIFICATIONS
The SLTA is a one-piece construction, externally wired device. The SLTA is connected via the SLTA connector cable, part number 205979, to the E-Bus port on Excel 10 controllers or wall modules.

Power Supply
The standard power supply is 9V at 500 mA with the connection plugs outer barrel positive (+) and the tip negative (-). Power On LED is located on the back of the Q7752A SLTA.

Transceiver Type:
The SLTA uses a transformer isolated, differential Manchester transceiver.

Status Information:
Service (LED) on the back of the SLTA provides status information.

A service request button for broad-casting the neuron ID on the E-Bus, is located on the back of the SLTA.

Mounting Options:
For permanent installations, the SLTA can be wall mounted using an SLTA mounting bracket. See Excel 10 Q7752A Serial Interface Installation Instructions, form 95-7511, for details.
