The Intel Hex Format - Lantronix CoBox-Micro User Manual

Supplemental Information
To send a setup record via Monitor Mode:
1
Configure a "master" Device Server with the desired parameters and place it on the
network.
2
Place another Device Server (the "target") on the network.
3
Enter Monitor Mode (with network support enabled) on the master Device Server
(see Monitor Mode on page B-1)
4
At the prompt, enter SC, the IP address of the target, and a carriage return.
5
Send the setup record to the target Device Server.
Note: For example, using Hyperterminal, copy the setup record and select
"Paste to Host" to send it to the Device Server. The Device Server
reboots with the new configuration.
To send a previously saved setup record to a Device Server via UDP, from a host PC, send
the FA (or FD) datagram to the "target" Device Server (see Network Configuration Using
UDP on page E-1).
Note: The Device Server responds with the FB datagram. Refer to the table.

The Intel Hex Format

With this format, 8-bit binary data can be sent and received as ASCII text. The
transmission is blocked in records, and every record has its own checksum.
The record begins with a colon (:) and consists of a block length (2-character Hex), a 16-
bit address (4-character Hex), and a block type (2-character Hex). It is built by adding all
binary 8-bit values and taking the complement, so adding all byte values (including length,
address, and type) should yield zero.
Example:
00000001FF
End record, type 01, length 00, address 00 00, checksum FF.
01002000805F
Data record consisting of one byte (value 80 Hex) for address 0020 (32 decimal).
