3.14 RS-485 Initial Setup
SA – Set the Address
Offset
The default address for the module is 01. You may assign any address from
0 to 63 (decimal equivalent).
The address consists of the hexadecimal switch setting plus the
hexadecimal SA (set address offset) value. For example, to set a value of 60
for the address, set the switch to C
hex
(12), then send an SA value of
30
hex
(48).
To set the address, follow these steps:
1. Send an SA (set address offset) command to the module. The example
SA command sets the address offset to 30
hex
(48):
Example SA command from host: #01SA30↵
Response from module: *01 PROGM OK↵
Valid SA command values are 00, 10
hex
(16), 20
hex
(32), or 30
hex
(48).
2. Use the rotary switch located on the top of the module to set a value of
0 to 15 (see Figure 3-12).
• Set the switch on one of the unlabeled marks for the values 1, 3, 5, 7,
9, B
hex
(11), D
hex
(13), or F
hex
(15).
• Set the switch on one of the labeled marks for the values 0, 2, 4, 6, 8,
A
hex
(10), C
hex
(12), or E
hex
(14).
3. Cycle power to the module to activate the new address offset.
