3.3 FAQ
Question Can a program be written to talk to the scale and record weight information?
Answer Yes , the Crane Scale provides a host communication language to access all aspects of weight data
and scale configuration. For full details see the Crane Scale manual.
Question Can multiple computers be connected to the scale at once via the Ethernet interface?
Answer No, the Crane Scale supports a single TCP/IP connection at a time.
Question Can a web page be accessed to view the scale weight?
Answer No, the Crane Scale web page interface provides a secondary means of configuring the
network
settings only.
Question What if Scale Discovery Utility does not find the Crane Scale even though it is connected to the
network.
Answer There may be some network firewall settings between the Scale Discovery Utility and the
Crane Scale that are preventing communications. Have the network administrator check the network
firewall settings to ensure UDP port 2362 and multicast IP address 224.0.5.128 are not being
blocked.
Question What if an error dialog message displays in the Scale Discovery Utility when Chat is pressed.
Answer Only one active connection to the scale Chat or host interface can be active at a time. Likely there is
another program running (perhaps on another computer) that is already talking to the scale.
Question Can the MSI-9750 hand-held or MSI-9850 meter be used with an 802.11b equipped crane scale?
Answer No, the 802.11b interface of the crane scale replaces the standard 2.4GHz radio in the
CellScale
product family. These radios are not compatible with each other.
3.4 Wireless Troubleshooting
The main challenge is getting the 802.11b equipped crane scale to associate with a Wireless Access Point (WAP).
Once this is accomplished, the crane scale can be further configured by using the Scale Discovery Utility.
The settings below are the default settings that the crane scalewill attempt to look for in an access point. Once the
ScCMP has associated these settings, they can be changed, provided they are changed on the crane scale and the
access point. At this point, encryption and authentication can be set up.
Access Point Settings (Case Sensitive):
SSID: Connect
Authentication: none (i.e. open) Encryption: none
Channel: Auto (1, 6, 11 preferred)
Mode: Infrastructure (as opposed to Ad Hoc) DHCP server: enabled
The ScCMP by default will look for an access point with an SSID of Connect. If it can't find Connect, it will then
look for an Ad Hoc network with an SSID of Connect. If that fails it will then associate with the strongest
unencrypted access point signal regardless of SSID. If there are more than one access point, the ScCMP will attempt
to associate with the SSID of Connect, regardless of signal strength. The ScCMP needs an access point without
authentication or encryption. It will not be able to associate if either of them are enabled. It can associate with any
channel, but 1, 6, or 11 are
preferred (assuming North America). The ScCMP by default will look for an access
point in Infrastructure mode. It will come up in BSS_Join mode.
Once the ScCMP has successfully associated with the access point, assuming that the module has not been assigned
a static IP address, it will attempt to acquire a dynamic IP address from any available
DHCP server on the network.
