4.2 Special Matchport Firmware
The Matchport module (112226) used by ABF version have a modifications in the firmware.
• Even with the card set to “Wireless Only”, if during boot-up it detects an Ethernet connection, it will
revert to Ethernet for that session only.
• When the cable is removed and power cycled, it will go back to a Wireless mode. This was done for
ease of configuration using DeviceInstaller (as opposed to the RS232 method).
Note
Power MUST be cycled for it to switch back to wireless mode - just removing the cable DOES NOT switch it
back to a wireless connection.
• The module creates a unique DHCP name from its MAC address (see Section 4.1.3).
• The baud rate of both serial channels is set to 19200 to match the settings of their Mega 8 indicators.
• The input and output buffers are always flushed.
• Two of the general purpose inputs are set to allow the module to be set to factory defaults
The first GPIO to set the module to Default and Wireless Mode Only.
• The TCP Port Numbers for the two serial channels.
This firmware uses 8023 and 8024. Take note of that if troubleshooting.
4.2.1 420 Core Firmware
New EDP command and different defaults.
• Default baud rate for the Printer Port is now 19200. DO NOT CHANGE THIS!
• Zero Track Band default is 1D
• Zero range default is 100%.
• New EDP command, “P” (no carriage return or line feed). If talking to the indicator, simply send “P”
and it will respond with a single frame of stream data, no matter the status. “SENT” will appear on the
420 screen for a couple second after the 420 is successful in sending the response to the “P” command.
Note
This DOES NOT mean the handheld device received the data, just that the 420 sent it. The 420 itself does not
know if there is a good network connection or not, but if it got the “P” from the network, then the downstream
data is working. If the indicator says “SENT”, but the data is not getting back on the network, then check the TX
line from the 420 CPU to the RX of the WLAN card, and the RX LED on the WLAN card to make sure it blinks.
• In weigh mode, ALL the keys on the keypad are DISABLED except the “ZERO” key. Operators
can only use the zero key. The zero key is like a Tare - zeroing off empty pallets and such before
taking weighments.
• Messages in error conditions:
Angle is over 3°, the display actually says “Angle”.
Overload or underload, the display shows “Over” and “Under”.
Note
Default indicator if any settings become corrupt to return to default settings. See Section 4.1.4.
