High Performance 2.4GHz Four ChannelA/B Backup Selector SystemModel 10943B

Model 10943B Four Channel L-Band Backup Switching System - 12153 CE

February 2009

General

Large scale communication installations require State-of-the-Art equipment. The 10943B provides the systems professional with an uncompromising combination of high performance and high reliability switching elements coupled together for L-Band backup systems. Standard redundant power supplies plus redundant system control interfaces deliver the ultimate in system reliability for critical applicationsCompact and high performance, the Model 10943B providescost effective, flexible switching capacity for smaller installa- tions, providing 4 channels of A/B (primary or backup) switch- ing. It is also provides both 1:1 or 1:4 modes. Bandpass is excel- lent for video, IF, RF and L-Band signals ranging to nearly 3GHz. Complete control and status of the unit is available at boththe front panel controls or the dual remote interface. Also pro- vided with the unit is a direct TTL alarm input connector for direct backup channel selection with priority assignment (for 1:4 mode), and an 8-bit driver port for controlling external devices. The unit is available with dual serial ports with provi- sion for the user to self-configure the serial mode of the indi- vidual ports (RS-232C, RS-422A or RS-485), or also available with a single serial port plus Ethernet (10/100BaseT).
