4.4.1 Message Format
All UDP event packets share the same header structure. The first two bytes represent the length of the
packet. The third byte represents the type of packet. (Note the packet length is in little-endian format.)
The types of packets are:
Packet Type
Value
Card Status
0x01
Card Error
0x02
File Transfer
1
0x05
Control Module Error
0x06
Calibration Status Messages
1
0x07

4.4.2 Card Status Message
Status messages are transmitted when a card changes its operational mode. For example, when a user
arms a card, its status changes from idle to armed. A corresponding status message will be broadcast out
the event port. The status message format is as follows:
Byte
Position
Value
1
Message Length (LSB) excluding the length bytes (0x0A)
2
Message Length (MSB) excluding the length bytes (0x00)
3
Message Type = Card Status (0x01)
4
Card ID (1 through 16)
5
Scanning Flag (0 = not scanning, 1 = scanning)
6
Armed Flag (0 = not armed, 1 = armed)
7
Calibrating Flag (0 = not calibrating, 1 = calibrating)
8
Uploading Flag (0 = not uploading, 1 = uploading)
9
Downloading Flag (0 = not downloading, 1 = downloading)
10
Updating Flag (0 = not updating, 1 = updating)
11
Idle Flag (0 = not idle, 1 = idle)
12
