Page 73: Section 4 Maintenance
This chapter contains general flight-line maintenance and troubleshooting procedures for installations interfaced to WX-1000/SKY497 display or an alternate display. Removal of components is on condition of failure. Troubleshooting is intended to aid in isolating failures to a defective assembly. Each time the TRC, directional antenna, or directional antenna cables (including connectors) are replaced, the TRC must be calibrated to the directional antenna (refer to paragraph 4.4.1).
Page 74: Service Menu
Installation Manual SERVICE MENU The Service Menu is intended as an aid in installing, testing and troubleshooting the SKY497. Service Menu items are to be used only for testing and troubleshooting an installation. The Service Menu is not intended to be used by the pilot during normal system operation. When interfaced to an alternate display the service menu functions must be performed by using an RS-232 terminal device, see appendix E for terminal device operating instructions.
Page 75: Calibration
SKY497 Installation Manual 4.4.1 Calibration NOTE Ensure transponder is in standby while doing calibration. Each time the TRC, directional antenna, or any of the directional antenna cables (including connectors) have been repaired or replaced the TRC must be calibrated. Calibration is accessed by selecting that option from the Service Menu (i.e., press SELECT with Calibration high-lighted).
Page 76: System Log
SKY497 Installation Manual The calibration value (000-359) is derived from a variety of measurements. Specific values are meaningless however, in a failed TRC, a varying spread may indicate problems with the directional antenna system (antenna, cables, or connectors) or the TRC.
Page 77: System Data
If you have problems with the SKY497, verify the configuration screens match the wiring diagrams (see figures 2-2 and 2-3) and have this information available when contacting Field Service Engineering. The field service engineer must have adequate information to diagnose a problem.

Page 89: Error Messages
Installation Manual ERROR MESSAGES SKYWATCH firmware is designed to generate error messages associated with a particular condition or step in the program. The 20 most recent errors detected by the system are saved in the System Log (see para 4.4.2). System Log can be accessed with a terminal device by using the Dump command. For your convenience, in Table 4-2, we have listed the error messages that have been associated with SKYWATCH installations.
Page 90: Table 4-3: Informational Error Messages
These messages do not necessarily indicate a current system failure and are provided for information only. Should the installer observe these messages in the error log without a SKY497 Failed message during normal operation, no service action is required. Table 4-3: Informational Error Messages ERROR NO.

Signal Name & Cable Characteristics A.1 INTRODUCTION This appendix defines the electrical characteristics of all input and output signals to the SKY497 system. Sufficient data is included to perform an electrical load analysis for the aircraft. The interface characteristics contained in this appendix are fully compatible with ARINC specifications where noted. Connection information identifies the connector-pin and signal names as they appear on the interconnect wiring diagram (figures 2-2 and 2-3) or, in the case of antenna cables, the connector type (e.g., BNC or TNC).
Page 94 VSWR 1.5:1. Refer to table 1-8. Impedance: 50 Ω ARINC 429 The SKY497 has two ARINC 429 receivers and one transmitter (see External Interface para 2.9). The receivers operate at either low speed (12.5 kHz) or high speed (100 kHz). The transmitter operates only at high speed (100 kHz).
Page 95 SKY497 Installation Manual SIGNAL CHARACTERISTICS ARINC 429 External Interface (Continued) Both transmitters (data sources) must be set to the same speed. The TRC will automatically adjust both receivers to the speed of the first detected incoming data. NOTE If 429 barometric altitude is used, it should be from the same source that is interfaced with the transponder or it must be at least as accurate as that source, i.e., ±...
