CRD-124/207 High-Alphabet Command Receiver/Decoder.

00Model CRD-124/207 Command Receiver/Decoder was developed specifically to operate on the solid-rocket boosters (SRB) during launch of the Space Shuttle. The unit is designed to replace the now obsolete Model CRD-111/202, and incorporates all the functions performed previously by the distributor units on the solid-rocket boosters (SRB). The new CRD-124/207 Command Receiver/Decoder receives radio frequency (RF) commands, discriminates and decodes them, sends and receives hardwired commands for cross-strapping, and implements ordinance initiation output. This CRD unit also provides the command interface for the Range Safety System (RSS), safe and arm device (S&A), and provides command status and performance data to the measurement system.

CRD-128 EFTS Command Receiver for Missiles and Remote Control.

00Model CRD-128 Command Receiver is a compact, cost-effective range safety receiver/flight termination receiver designed specifically for missile and remote control applications. The next generation receiver is specifically designed for the Enhanced Flight Termination System. Lightweight, low power, small volume (3.7 in3), and configurable digital processing with embedded COMSEC (3DES) make the receiver ideal for numerous data link applications.

CR-123 Cost Effective IRIG Command Receiver/Decoder.

00Model CR-123 is a compact, cost-effective Command Receiver developed specifically for range safety flight termination applications on vehicles utilizing the IRIG tone format. This design incorporates "Hi-Rel" components and sufficient redundant circuitry to ensure reliable, fail-safe operation. The unit was engineered to be a cost-efficient means of meeting the ELV parts program.

CR-125 Enhanced Cost Effective IRIG Command Receiver/Decoder.

00Model CR-125 Command Receiver/Decoder is designed for range safety flight termination applications on Missiles and Launch Vehicles that require advanced monitoring and switching features. The CR-125 is compatible with the IRIG tone modulation format and meets the requirements of RSG/RCC 313-89 and ELV-JC-002 (tailored).
