subject. In addition to this chapter, see Chapter 

6, “Communications Protocols,” 

and

All Encompass 4/4800 Multiprotocol Reader commands are preceded by the start-of-
message character (#). The end-of-message sequence expected from the host is a car-
riage return (CR). The Encompass 4/4800 Multiprotocol Reader terminates messages 
with a return and a line-feed (CR/LF). For example, the command #01 Switch To 
Command Mode is typed as follows:

#01<ENTER>

where <ENTER> is the Enter or Return key.

Some command characters may be represented by the letter N. This letter indicates 
you are to supply a value. Maximum valid entries are the numbers 0 through 9 and the 
uppercase letters A through F. These letters allow for as many as 16 available user 
responses and are based on the hexadecimal numbering system. 

Commands have at least two characters following the # character. 

Table 5-1 

shows the 

basic structure of a four-character command.

#1005 

#

All commands are preceded by the # character.

1

Indicates the command group. This command is in Group 1- 
Communications Port Control.

0

Indicates the command subgroup. In this example, all commands with 
a second digit of 0 apply to the main port.

0

The command digit. In this example, the 0 indicates that this command 
affects the baud rate.

5

Indicates the setting. Normally this is a variable and is usually a 
hexadecimal value from 0 through F. In this example, 5 sets the baud 
rate to 9600, the factory setting. In some commands, this digit may be 
a four-place hexadecimal string or a character string.
