Where length = type + dest port + payload + checksum = 1 + 1 + 5 + 1 = 8

Configure Communication Port (0x3E)

Configure one of the communication ports. Current setting can be retrieved using Get Port

Configuration (0x3F).

Byte offset Description

2 Length = 20

3 Type = 0x3E

5 Baud Rate (see below)

6 Data Bits

7 Stop Bits

8 Parity

9 Maximum packet length

10 Maximum packet delay (ms)

11 Protocol parser: MOD 2.18

0: SLA Protocol (SLA-1500 at Port 0 only)

1: Scan Eagle Aquarius packet parsing & SLA Protocol

2: Reserved 0

3: Reserved 1

4: Port Not Used (allows use by other applications)

5: TCP Pass Through

6: Raw Pass Through (direct pass-through with no change)

12 – 13 Local inbound port number where UDP packets are expected

LSB then MSB

Ethernet port were all payload data will be received.

Hardware opens a new socket to listen on this port.

14 – 17 Destination IP address of host where UDP packets will be sent

18 – 19 Port number where host is listening.

Hardware opens a new socket and sends data to the outbound

destination IP Address at the destination port number.

20-21 AttNav port number (default 65100)

If configured as Pass Through, data on this port is passed on to
