5.5.4.9.7.8 RS-232 Inputs
The RS-232 Inputs diagnostics page allows the display of serial data that is being received and is useful
for determining if the GDL 88 is receiving data on each connected port. To access this page, touch
External Systems
→ GDL 88 → Diagnostics → RS232 Inputs. Select the desired port by touching the
Port key and selecting the RS-232 channel from the list. The data log can be paused by toggling the
Pause key. Clear the data log by touching Clear Log.
5.5.4.9.7.9 ARINC Inputs
The ARINC Inputs diagnostics page allows the display of ARINC 429 data that is being received over
each GDL 88 ARINC 429 port. To access this page, touch External Systems
→ GDL 88 → Diagnostics
→ ARINC inputs. Each port can be chosen for display by touching the Port key and toggling between
the input ports. Select a port to display. The GTN will then display the label, SSM, Data, and SDI for
each GDL 88 ARINC 429 input port. This is useful for determining if the expected labels are being
received and also for troubleshooting incorrect or swapped wiring to the input ports. The data log can be
paused by toggling the Pause key. Clear the data log by touching Clear Log.

→ GDL 88 → Diagnostics → HSDB (Ethernet). This page displays
whether or not each port is receiving data and displays whether the port is connected or not connected.
The configuration status of each installed HSDB LRU is also displayed.
