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 

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 8-1). 
Note: The Device Server responds with the FB datagram.  Refer to the table. 

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). 

For communication with the node, the following block types are defined: 

Data block program memory (firmware) 

00 

End record 

01 

Data block configuration memory
