Command Set 4-8
To turn the output off you could use the command:
Command:
$1DO00
Response:
*
Command:
#1DO00
Response:

Digital output 0 shares the connector pin with the Alternate RTS. Bit 3 of byte
4 of the SetUp command is used to configure this pin as either digital output
or RTS function. See chapter 5 for details.
The digital output setting is not stored in nonvolatile memory. If a power
failure occurs, the digital output will be 0 upon power up.
The DO command is the only means of changing the digital output. There
is no software provision to read the state of the digital output.
Extended Address (EA)
The Extended Address (EA) command allows the user to set the two-byte
address to be used with Extended Addressing (see Chapter 7). The
argument of the command specifies the hex ASCII values of the two
characters to be used as the Extended Address. For example, if the address
is to be set for characters ‘01’:
Command:
$1EA3031
Response:
*
Command:
#1EA3031
Response:
*1EA3031A8
Note that ‘30’ and ‘31’ are the hex ASCII values for characters ‘0’ and ‘1’
respectively.
The EA command is write-protected and must be preceded with a WE
command.
The address data may be read back with the Read Extended Address (REA)
command.
