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.
