Demystifying the CA750 Wi-Fi Log

One of the new features introduced in the CA750 Firmware v1.18 and improved upon in CA750 Firmware v2.01 and v2.07 is the ability to generate a Wi-Fi log from the cart's wireless networking module. 

To Generate the Wi-Fi Log:

First ensure that the USB drive is empty, or that all configuration and firmware update files are in folders, and therefore hidden from the cart's view. 

1. Plug the Avizia Flash Drive included with the cart (or another USB flash drive formatted FAT or FAT32) into the port on the left hand side of the console 

2. Press and hold   [Home]  +   [Workstation Mode] for approximately 10 seconds or until a message appears. 

3. The message "The Wi-Fi Log has been Generated" appears onscreen. 

4. Select "Dismiss" 

5. Unplug the USB Flash Drive and plug it into any Mac or PC computer. 

6. Open the CA750Log.txt file in a notepad or text reader. 

 

Status Information 

Example:

[Status Information]
IP address : 10.10.10.10
TC version : TC7.3.6.ea51021
Wi-Fi version : Module1 - 1.00, Module2 - 1.00
CA750 version : 2.01 / 2.01 (A)
Configuration : Monitor - Dual / Battery - 1

This section includes general information regarding the cart. 

IP Address: The IP Address of the Codec. You can enter this information into a web browser to remotely alter settings and create a backup of your codec settings. 

TC version: This is the software version on the codec itself. 

Wi-Fi version: This will provide the version information for the Wi-Fi modules. If this is blank, then the cart's brain is not receiving information from the Wi-Fi modules. Please file a support ticket. 

CA750 Version: This is the Firmware version on the cart. There are two chips inside the carts CPU or brain, and each chip is updated independently.

To update the firmware on your cart, please visit avizia.com/firmware for instructions, release notes and the latest version files. 

Wi-Fi Information

Example: 

[Wi-Fi Information]
Mode : SC
Status : Connected
SSID : WiFiSSID
ENC : WPA2
AUTHTYPE : PEAP
REGION : US

This section includes information specifically about the Mode the cart is operating in and the SSID it is connected to. 

Mode: SC or WGB.

  • SC: Single Client Mode.
    • In this mode, the Codec and the Brain/CPU each have their own wireless IP address, and a separate radio connection. 
  • WGB: Work Group Bridge Mode (also known as Multi-Client Mode)
    • In this mode, the Codec, Brain/CPU and optional PC all share a single Wi-Fi connection. Each component will have its own IP address, as the Wireless module uses one-to-many functionality. 

Status: Options are Connected or Disconnected. 

SSID: The SSID (Service Set Identifier) that the cart's Wireless module is connected to. 

ENC: Encryption Type. This is set by your Wireless Network Administrator. Avizia recommends the latest standard of encryption which is WPA2. 

AUTHTYPE: Authentication Type. This is set by your Wireless Network Administrator.

REGION: Many countries use specific channels. For a robust list of country codes and their associated channels, see the Cisco Wireless Configuration Appendix on Supported Country Codes. Only "US" or "WWR" (world-wide-region) should be visible. 

Brain Information

Example:

[Brain Information]
Serial Number : DNT16161616
MAC Address : BB:CC:66:99:11:77
Brain Rev. : A

This section provides information specifically about the CPU or Brain inside the tech bay of the cart. 

Serial Number: This is needed for tracking purposes or for registering the cart with Fleet Monitoring

MAC Address: This is the MAC of the Brain itself. 

Brain Rev.: This is a hardware specific revision provided for troubleshooting or part replacement purposes. 

Wi-Fi List

Example: 

[Wi-Fi List]
"public" ee:aa:44:55:ff:33 -65 36 11na AP Open/Shared NONE
"Private" aa:ee:55:ff:44:33 -65 36 11na AP WPA2-PSK AES
"Private-mobile" 33:66:44:55:44:33 -66 36 11na AP WPA2-EAP AES

 

The items in the Wi-Fi list are in the following order: 

SSID | AP MAC Address | Signal Strength | Channel | Standard | AP | Encryption | Security

SSID: The SSID, or network name, identifies your Wi-Fi network. 

AP MAC Address: Many locations have multiple Access Points (APs) with the same SSID. The MAC Address is listed to provide assistance determining which is which in the Wi-Fi List. 

Signal Strength: The signal strength is measured in negative. The closer to zero the better, so lower numbers are best. See below for more information. 

Channel: Wireless channel the AP is operating on. 

Standard: 802.11 standard. For a complete listing of supported modes, see chart:

  802.11 (legacy) 802.11a 802.11b 802.11g 802.11n
Max Speed 1.2 Mbit/s 54 Mbit/s 11 Mbit/s 54 Mbit/s 150 Mbit/s
Frequency 2.4 GHz 5.8 GHz 2.4 GHz 2.4 GHz 2.4 & 5 GHz
Year 1997 1999 1999 2003 2009

*Complete Original Chart and more information can be found at Android Authority

Encryption: Supported Encryption types include: None, WEP, WPA-TKIP, WPA-TKIP/AES, WPA/WPA2-TKIP/AES, WPA2-AES

NOTE:

  • WPA2 is recommended, as all other encryption types are considered outdated and non-secure. 
  • If your network is running mixed-mode (WPA and WPA2), the cart Wi-Fi must be configured in "WPA-TKIP/AES" mode to connect to it.
  • WPA2 with TKIP is not currently supported without an update to the network module. Please contact support@avizia.com for more information. 

Security: Supported security protocols include OPEN, TTLS, LEAP, PEAP, EAP-FAST and PSK. 

Wi-Fi Quality

Example:

[Wi-Fi Quality]
Signal Quality = 100
Signal Strength = -53
Noise Level = -96

Signal Quality: This is an indicator of the quality of the signal.  100 is best, anything below 70 will result in degraded call quality. 

  • 100: Excellent
  • 100 to 70: Recommended Quality
  • 70: Threshold for Video 
  • 60: Threshold for standard data
  • 50: Failure

Signal Strength:  This is an indicator of the strength of the signal from the AP, measured in negative numbers. In this case, the lower number appears the better. 

  • -30 = Ideal 
  • -30 to -60 = Recommended Strength
  • -70 = Threshold for Video
  • -90 = Failure

Noise Level: This is an indicator of how much noise is on the line. 

  • -96 = Typical

Wi-Fi Radio

Example:

[Wi-Fi Radio]
Radio mode is 802.11a-n

This provides which revision of the IEEE standard that is in use currently.

See the chart above for more information. 

Wi-Fi Status
