The default address as programmed at the factory is 01. If a different address is required, it may be
changed using either RS-232 or 485. After making the proper serial connections, use the command *00X
to read the default address. Use *00Xdd, where dd = the new address. If the old address is known, use
DDXdd, where DD is the old address and dd is the new address. See the section on "Serial
Communication: Commands" for more on command structure.
All commands listed in Appendix B are available for RS-485 use by inserting an asterisk and the unit's
address in front of the command.
Ex) Set the units of measure on channel two (2) to %.
*10UM203Cr
The command, *00XCr can be used to poll the unit for its current address setting using either RS-232 or
RS-485.
