VP-81K - Kramer Protocol 29

11.2 Kramer Protocol 3000

This RS-232/RS-485/Ethernet communication protocol lets you control the

machine from any standard terminal software (for example, Windows®

HyperTerminal Application).

11.2.1 Protocol 3000 Syntax

Host message format:

Start Address (optional) Body Delimiter

# Destination_id@ message CR

Simple command (commands string with only one command without addressing):

Start Body Delimiter

# Command SP Parameter_1,Parameter_2,… CR

Command string (formal syntax with commands concatenation and addressing):

# Address@ Command_1 Parameter1_1,Parameter1_2,… |Command_2

Parameter2_1,Parameter2_2,… |Command_3 Parameter3_1,Parameter3_2,…

|…CR

Device message format:

Start Address (optional) Body Delimiter

~ Sender_id@ message CR LF

Device long response (Echoing command):

Start Address (optional) Body Delimiter

~ Sender_id@ command SP [param1 ,param2 …] result CR LF

CR = Carriage return (ASCII 13 = 0x0D)

LF = Line feed (ASCII 10 = 0x0A)

SP = Space (ASCII 32 = 0x20)
