RTS Operation G-3
The RTS output and the delay time values are disabled while in Default
Mode.
The RTS output is located on digital output bit 0 (DO0/RTS). The digital
output is an open-collector transistor and will require an external pull-up
resistor. The external pull-up may be eliminated if a module contains one
unused digital input bit. All D1000R/2000R series digital input bits contain
an internal 10K ohm pull-up resistor to +5Vdc. Simply connect the DO0/RTS
terminal to the unused digital input.

IDentification (ID)
The IDentification command allows the user to write a message into the
internal nonvolatile memory which may be read back at any time using the
Read IDentification (RID) command. The message may be up to 16
characters long and has no affect on the module operation. Useful informa-
tion such as the module location, calibration date or model number may be
stored for later retrieval.
