485DSS Address Command
A command is required to address each individual 485DSS module. Once addressed, the
module will transparently convert serial data. The address command can only be
transmitted at 9600 baud, and if the command is transmitted at any other baud rate, the
command will be ignored by the 485DSS module. The address command has the following
form: Xoff character, the most significant address character, the least significant address
character, and SOH character. Xoff and SOH require a combination of keys to produce the
desired character in HyperTerminal. Simultaneously pressing the Ctrl key and the S key
(Ctrl+S) will produce the Xoff character and simultaneously pressing the Ctrl key and the A
key (Ctrl+A) will produce the SOH character. The address range of the 485DSS module is
from 0 to 255 in decimal or 0 to FF in hex. With HyperTerminal all addresses must be
entered as hex.
For an example, to set a 485DSS module with an address of 8F in hex (143 in decimal), the
address command is: Xoff 8 F SOH. To enter this data into HyperTerminal, the key
sequence is Ctrl+S, 8 key, F key and Ctrl+A. If the address is less than 10 hex, a leading
zero is required.
