CRS-170A L-Band 1:1 Redundancy Switch Introduction 1.3 MN/CRS170A.IOM Revision 13 Functional Description The CRS-170A performs the Tx and Rx coaxial switching required for redundant modem operation with an outdoor BUC and LNB. The Tx (transmit) side switches four modem output signals that are multiplexed onto the transmit coaxial cable: • 950-2250 MHz L-band transmit RF; • 10 MHz BUC frequency reference; • 600 KHz BUC FSK control and status communication; • BUC DC power supply.
CRS-170A L-Band 1:1 Redundancy Switch Introduction • MN/CRS170A.IOM Revision 13 Fourth, +12V is routed from each modem to the CRS-170A for operational power. This power from both modems is diode OR’d so that the switch remains active if power is lost from one of the modems. Mode Switches – The Mode DIP switches, located on the antenna side of the CRS-170A, allow the switch to operate in two different modes: Normal (Intelligent Controller) Mode and SDM-300L/CDM-600L (Dumb Controller) Mode.
CRS-170A L-Band 1:1 Redundancy Switch Introduction MN/CRS170A.IOM Revision 13 Modem Unit faults only; Modem Unit faults or Receive Traffic faults; Modem Unit faults or Transmit Traffic faults; or all three. Sect. 4.9 Configure Switch DIP Settings Two green LEDs are located on the antenna side of the CRS-170A. They provide a visual identifier for the Online unit.

The SMS-301 itself has redundant power supplies, and feeds power to the CRS-170A through the control cable. Online/Backup Modem configuration matching is provided by the CRS-150 controller communication with the CDM-600L (CLM-9600L) modem. The SMS-301 does not automatically configure the Backup Modem.
CRS-170A L-Band 1:1 Redundancy Switch Introduction MN/CRS170A.IOM Revision 13 current sharing circuit ensures that power is taken equally from the two modems in normal operation. In the event that one of the two units is removed, however, the remaining modem can supply all current requirements. The modems supply +12 volts DC (at a combined total of 400 mA max) and -12 volts DC (at a combined total of 120 mA max). Maximum power consumption occurs in a serial LVDS mode at maximum data rate (20 Mbps).

Chapter 3. SWITCH CONNECTORS AND PINOUTS 3.1 Cabling Connection Types The cable and connector types described in this section are commonly used in many Comtech EF Data products. Each cable type is typically dedicated to a specific mode of operation. The CRS-170A L-Band 1:1 Redundancy Switch and its compatible Traffic and Redundant Modems may not use all of these connector types. The European EMC Directive (EN55022, EN50082-1) requires that you use properly shielded cables for DATA I/O.
CRS-170A L-Band 1:1 Redundancy Switch Switch Connectors and Pinouts MN/CRS170A.IOM Revision 13 These connectors are available in two coupling styles: Bayonet or Threaded: • Bayonet Coupling Style – The jack has a pair of guideposts that accommodate the plug’s lockdown slots. This lockdown design provides secure assembly without over-tightening the connection. • Threaded Coupling Style – The jack features external threads.
CRS-170A L-Band 1:1 Redundancy Switch Switch Connectors and Pinouts 3.1.1.5 MN/CRS170A.IOM Revision 13 Type ‘SMA’ (Subminiature Version ‘A’) Type ‘SMA’ connectors feature a Threaded Coupling design similar to Type ‘TNC’, Type ‘N’, and Type ‘F’ connectors. 3.1.2 D-Subminiature Cable Connections Type ‘D’ Connection Type Example Chassis Receptacles: (TOP) Female (BOTTOM) Male Type ‘D’ Cable With Jack Screws (Female Shown) Figure 3-2.

Appendix A. CABLE DRAWINGS A.1 Overview This appendix provides technical specification drawings for the cables used with the CRS-170A L-Band 1:1 Redundancy Switch. These cable details are grouped into two categories – Control Interface Cables (Sect. A.2), and IF/Data Interface Cables (Sect. A.3). The European EMC Directive (EN55022, EN50082-1) requires that you use properly shielded cables for DATA I/O. These cables must be double-shielded from end-to-end, ensuring a continuous ground shield.
