GMX 200 Installation Manual Page 5-1190-00607-04 Revision F5 4 B System Configuration/CheckoutOnce the GMX 200 unit has been installed, configure the unit for the particular installation and thencomplete the checkout procedures in Section X 5.5X to verify proper operation. The steps that are notapplicable to a particular installation may be skipped. A checkout log sheet is included in X Table 5-3X to befilled out during the configuration and checkout procedure. The completed checkout log sheet should bemaintained with the aircraft permanent records.5.1 2 8 B System Configuration Overview5.1.1 6 5 B GMX 200 Basic Data Port ConfigurationThe basic GMX 200 supports five serial ports on connector J2001. Four of the ports are RS-232 and onecan be either RS-422 or RS-232. The usage of each port is assigned during the External Data Source setup(see section X 5.3X). Samples of typical wiring configurations are shown in X Appendix EX.The following table shows the suggested port usage; however, the GMX 200 must be configured to matchthe installed wiring configuration.NOTEOnly one traffic source may be connected to the GMX 200 I/O at one time.NOTEOnly one FIS source may be connected to the GMX 200 or GMX 200I/O at one time.Table 5-1.

It is recommended that GPS altitude be configured for useby the GMX 200 in installations that are using the GNS 500 series TAWS.[2] Altitude is used by the GMX 200 for terrain awareness. If the terrain awareness function is not enabled, analtitude encoder is not required. GPS altitude may be provided instead of pressure altitude, in which casethe altitude encoder input is not required.[3] A GX-series unit running software version 3.2 or higher and enabled for extended mode and a GNS 480(CNX80) unit is capable of receiving altitude data from a pressure altitude source and passing the data tothe GMX 200. In this case, an altitude encoder is not required.[4] Only one NAV receiver (GNS 480 (CNX80)with NAV receiver, or SL30) may be connected to the GMX200.[5] The TCAD or TIS-A function requires the GMX 200 I/O model
