11.0 SPC [T-Series Datasheet]

Overview

The SPC terminal has several uses:

  • Outputs diagnostic timing signals while streaming (see Stream Section for details)
  • Can be used to force special startup behavior.

Startup Behavior

To force special startup behavior, securely install a short jumper wire from SPC to one of the following digital I/O lines as described below. The jumper needs to be installed before reset, so make sure the jumper is securely clamped in SPC and the given FIO or AIN terminal, then power up the device.

The jumper must be securely installed.  Don't try to just hold a wire in a loose screw terminal or touch a wire to the screw head.

T4

 

FIO4 - Force Boot to Main Firmware:

Force boot to main firmware (internal) image. Used to boot the internal firmware even if its checksum is bad. Lua scripts will not be loaded during boot up when FIO4 is connected to SPC. 

FIO5 - Force Overwrite Main Firmware:

Force copy of backup image to overwrite internal image. Used to load the external firmware even if its checksum is bad.

FIO6 - Factory Reset:

Factory reset. Sets the start up configuration to factory settings. Disables Lua script at startup.

FIO7 - Boot to Emergency Firmware:

Load emergency image. This option loads a firmware image with minimal functionality (similar to Windows safe-mode). Used to recover from firmware corruption or bugs. The update process is about all that can be done while in this mode.

AIN3 - Configure Static Ethernet:

Added in firmware 1.0027.

Temporarily sets the Ethernet configuration as follows:

DHCP: Off
IP Address: 192.168.1.204
Subnet: 255.255.255.0
Gateway: 192.168.1.1
DNS: 8.8.8.8
Alternate DNS: 8.8.4.4
   

_DEFAULT Ethernet settings are not changed.

Both LEDs blink in unison 5 times to confirm that the jumper was detected.

This static Ethernet configuration is compatible with a direct Ethernet connection.

FIO0 - Force Boot to Main Firmware:

Force boot to main firmware (internal) image. Used to boot the internal firmware even if its checksum is bad. Lua scripts will not be loaded during boot up when FIO0 is connected to SPC. 

FIO1 - Force Overwrite Main Firmware:

Force copy of backup image to overwrite internal image. Used to load the external firmware even if its checksum is bad.

FIO2 - Factory Reset:

Factory reset. Sets the start up configuration to factory settings. Disables Lua script at startup.

FIO3 - Boot to Emergency Firmware:

Load emergency image. This option loads a firmware image with minimal functionality (similar to Windows safe-mode). Used to recover from firmware corruption or bugs. The update process is about all that can be done while in this mode.

AIN3 - Configure Static Ethernet:

Added in firmware 1.0291.

Temporarily sets the Ethernet configuration as follows:

DHCP: Off
IP Address: 192.168.1.207
Subnet: 255.255.255.0
Gateway: 192.168.1.1
DNS: 8.8.8.8
Alternate DNS: 8.8.4.4
   

_DEFAULT Ethernet settings are not changed.

Both LEDs blink in unison 5 times to confirm that the jumper was detected.

This static Ethernet configuration is compatible with a direct Ethernet connection.

If the device has become unresponsive, the easiest order is:

  1. Factory reset
  2. Force copy of backup image to overwrite internal image.
  3. Load emergency image.

The T-Series devices have two different firmware images:

  • The "primary firmware image", which is synonymous to "main firmware", is the firmware image used when the device is working properly. The primary firmware image (when being used) exists in the microcontroller's internal flash (for execution) as well as on the external flash chip as a backup image.
  • The second firmware image is an emergency image that implements a minimal amount of features. This image can be loaded using the SPC terminal and allows you to forcefully load a new version of firmware onto the device.
