Chapter 6: ASCII Remote Control
6.1 Installation
The rear panel Ethernet jack can be connected directly to a computer with a crossover
cable, or to a network router or switch with a straight cable.
6.2 ASCII Remote Control Commands
6.2.1 Introduction
The Model E responds to ASCII command strings to control the unit remotely with
third-party control systems. Every control available on the Remote Control Panel can
be accessed with command strings.
To test ASCII commands:
1. Enter the Model E’s address as a target for Telnet.
2. At the prompt, enter the command strings as described below.
Two command formats are supported:
• ASCII text format extended with a binary byte at the beginning and a binary check-
sum byte at the end. The check-sum enhances the reliability of the transmission.
0xFE Command <CR> check-sum
0xFE means an 8-bit byte with the hexadecimal value FE, 254 in decimal, 0111
1111 in binary (sent left to right).
• ASCII text format:
Command <CR>
This format is appropriate for quickly testing a command from a terminal. We rec-
ommend using the extended format for highest reliability.
The Command is a text command string (7-bit ASCII characters only). <CR> is the car-
riage return character (ASCII value 13). Each command requires a carriage return at the
end of the line. We will not show this in the examples.
