916 Wireless
916 MHz Transceiver
Part Number: CC15431-1
Features
The Comtec Wireless 916 is a 916
Mhz radio designed for OEM applications that operate in the unlicensed
FCC band between 902-928 Mhz. The
Wireless 916 can be used for communications where physical connection
is not desired. The following objectives
can be achieved with the Wireless 916, (i) pro vides a
limited range radio (20-30 feet line of sight), (ii) minimizes parts count and associated cost, (iii) acts as a
cable replacement when used together with Comtec
Wireless printers. When combined with Comtec’ s Intelligent Wireless Controller (part number CQ13967),
the Wireless 916 can be attached to any RS232C port.
T o minimize integ ration headaches, the Wireless 916
has modular FCC approval, which means that no additional FCC approval is required by the OEM

(Part Number CC13626)
Software When the Intelligent Wireless Controller (P/N CQ13967) is not used, Comtec can provide C
source code for a CS/CDMA collision avoidance communications protocol. This software
supports multiple radio pairs operating in proximity to each other, and implements error
detection, retries and radio address association. The radio address association algorithm is
based on radio or product serial number.
