5 System Configuration/Checkout
Once the GMX 200 unit has been installed, configure the unit for the particular installation and then
complete the checkout procedures in Section 5.5 to verify proper operation. The steps that are not
applicable to a particular installation may be skipped. A checkout log sheet is included in Table 5-3 to be
filled out during the configuration and checkout procedure. The completed checkout log sheet should be
maintained with the aircraft permanent records.
5.1 System Configuration Overview
5.1.1 GMX 200 Basic Data Port Configuration
The basic GMX 200 supports five serial ports on connector J2001. Four of the ports are RS-232 and one
can be either RS-422 or RS-232. The usage of each port is assigned during the External Data Source setup
(see section 5.3). Samples of typical wiring configurations are shown in Appendix E.
The following table shows the suggested port usage; however, the GMX 200 must be configured to match
the installed wiring configuration.
NOTE
Only one traffic source may be connected to the GMX 200 I/O at one time.
NOTE
Only one FIS source may be connected to the GMX 200 or GMX 200
I/O at one time.

Ryan TCAD, or option [5]
[1] GPS altitude (e.g. from the GNS 430/480/530 or CNX80) can be used as the GMX 200 altitude source
instead of pressure altitude (altitude encoder). It is recommended that GPS altitude be configured for use
by 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, an
altitude encoder is not required. GPS altitude may be provided instead of pressure altitude, in which case
the 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 to
the 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 GMX
200.
[5] The Ryan TCAD function requires the GMX 200 I/O model
