Basic Interface Specifications
RS-232C Communication
*The underlined options show the factory settings for communication with NIDEK devices.
The settings of Parameter 4 Com mode to Parameter 9 CR code are changeable.
For the procedure for changing the parameter settings, see “Setting Parameters” of the LM-
1800P/LM-1800PD operator’s manual.
If the Com mode parameter is set to “NIDEK”, Parameters 5 Com mode to 8 Stop bits are
automatically set for connection with NIDEK devices; once the parameters are set, the set-
tings are unchangeable.
If the Com mode parameter is set to “NCP20”, Parameter 7 Data bits is automatically set to
8bit; once the parameter is set, the settings are unchangeable
The settings of Parameter 5 Baud rate, Parameter 6 Parity and Parameter 8 Stop bits are
changeable.
• Be sure to set the Auto print S and Auto print R/L parameters to Off before communication.
Failure to do so could cause a printer error.
• Priority of interface (RS-232C/USB)
The communication is established with the port received data first.
When the Com mode parameter is set to “NIDEK” or “NIDEK2”, communication is possible only
with RS-232C. After the RS-232C communication is normally complete, data is sent through USB
interface in NCP10 mode.
