| 81 | Digital word input (DWI) | Contains CCC logic cards and associated power supplies.
Unit provides for entry of multi-bit words to computer. |
| 42 | Digital system output | Contains CCC logic cards and associated power supplies.
Unit provides for outputs of single bit and multi-bit messages from computer to simulator. |
| 82 | Digital system output | Same as unit 42. |
| 65 | Digital systems output | Same as unit 42. |
| 66 | Digital-to-analog (D/A) converter | Contains CCC logic cards and associated power supplies.
Unit converts digital information to analog information for display use. |
| 67 | D/A converter | Same as unit 66. |
| 68 | D/A converter | Same as unit 66. |
| 75 | D/A converter | Same as unit 66. |
| 77 | Peripheral cabinet, DCE | Contains analog-to-digital (A/D) converters and digital-to-
analog (D/A-F) (fast), which are used to convert analog signals to digital information and vice versa. |
| 56 | Peripheral cabinet, DCE | Contains analog resolver (A/R) units which accept analog
signals from digital-to-analog (D/A) converters and drive synchro resolvers and control transformers, primarily in instruments. |
| 40 | Switching cabinet (guidance and navigation) | Contains relay logic cards, and circuit interrupter cards.
Unit drives digital displays in the IOS. Unit contains relays that are associated with the command module, stabilization control system (SCS), inertial measurement unit (IMU), Greenwich mean time (GMT), and computer control system. |
| 39 | Switching cabinet (in-flight test subsystem and voice communications) | Contains amplifier s, filters, relays, and network cards. Unit
simulates audio signals representative of radio frequency, VHF/AM, and S-band communication systems, interphone system, and astro loops (to GSE umbilical) and the emergency key. |
| 62 | Peripheral cabinet, DCE-DWO | Same as unit 42. |
| 34 | Peripheral cabinet (Up-data link telemetry and simulation of digital command system) | Contains relay cards, network cards, and the 400-cycle
inverter. Provides information for telemetry and 400-cycle power to data storage unit in the C/M. |
| 30 | Telemetry cabinet 1 | Contains line drivers, associated power supply, pulse code
modulation fault controls, attenuator, monitor test shelf. Unit accepts system faulting control signals from computer and IOS to provide for systems faulting. |
| 76 | Peripheral cabinet, biomedical | Contains GFE biomedical tape recorder used to supply bio-med signals to PCM telemetry system. |
