Model 914-X Series Diagnostic GUI
The 914-X Series has advanced diagnostics available over a dedicated RS-232 port on the
console 914-HDE
motherboard
. This one port gives access to all* 914 cards in the 914-X Series system, including those at the
remote side if the fiber optic link is established. This diagnostic link is critical during the setup phase of any system,
as it gives access to the settings of any port in the system. This is useful to configure serial port protocols, Ethernet
negotiation settings, and any special video settings, for example.
Do not connect directly to the REMOTE 914-
HDE RS232 diagnostic port for configuration purposes, as the settings will not be retained.
*914-HDV2 has its own diagnostic port
Figure 5-1 shows a typical setup between a 914 card and a PC to obtain diagnostics information from both console
and remote ends.
Figure 5-1: Basic Diagnostics Setup
The diagnostics serial port configuration is as follows:
Speed: 115200 baud
Data bits: 8
Stop bits: 1
Parity: None
Flow Control: None
Included with every 914-X Series card is a pigtailed jumper for the RS-232 diagnostic port, as shown in the figure
below. This cable plugs into J8 on the console 914-HDE PCBA. To install the cable, the plug is pressed down into
the connector and should be epoxied in place for permanent connection. Extra cables provide firmware update
access for individual cards.
