Nikon Communication Interface Manual
1. Introduction
This manual explains how to connect Nikon Total Stations and external devices by
serial interface. About hardware and communication software necessary to the
connection are briefly described as well.
2. Interface system
The interface is directed by RS-232C. External devices must have a RS-232C port.

!!!CAUTION!!!
-Connection to the instrument side must follow the pin assignment above.
Misconnection may result in malfunctioning.
-By connecting RS-232C communication signal from external device and GND
to the pin #1,#2, and #5 on instrument side, the external device can be
download/upload data to the instrument.
-Electricity can be provided through pin #3 and #5 on the instrument, even if
the clip-on battery is mounted. The rated apparent power is DC7.2-11V (4.5
V to 5.2 V for Nivo only), Max 1A. Not to use the out-of-range power; it may
result in malfunctioning.

5. Nikon Communication commands
5-1. Protocol
“Protocol” is a set of rules applied to the communication in order to receive/send data securely.
It is independent from contents of receiving/sending data.

- SOH (01h): Header; Start of the communication
- Sender/Receiver codes: T: Instrument (Total Station)
R: Data Recorder
C: Other external device
Ex.) When sending data from an external device to the instrument, the code
becomes ‘CT’. If outputting data from instrument to an external device, it is
‘TC’.

Nikon Communication Interface Manual
- BCC: consists of 1-byte characters.
BCC= (S MOD 40h) + 20h (h = hex)
“S” in above formulae is the lower one byte of the total sum from “Sender
code” to “ETX” (=before BCC). “BCC” can be any value between 20h and
5Fh
* Compare the BCC in the received data and the calculated value.
If they are the same, the communication was successfully done.
- EOT: Trailer; End of the communication
The “CR/LF” is added at the end.
EOT = 04h
CR = 0dh
LF = 0ah
5-2. Procedures
-When instrument receives a block of data, BCC is checked and ACK is to be returned if the
block was successfully received. NAK is to be returned if an error is reported.
-If a NAK is received by the instrument, then the last block is to be resent by the instrument,
however, the count of NAK is not checked by the instrument, therefore, it is
recommendable to stop sending data by external devices side in such a case in order to
avoid any trouble which may be triggered in the hardware.
-No reply (ACK) is required to ACK/NAK.

5-3. Commands/Data format
Three types of commands are available;
a) Remote control command: Change function. Most commands do not follow any data output.
b) Data set command: Set instrument settings such as temperature, pressure etc. No data output follows.
c) Data output command: Output measured data, setting data etc. Follows data output.
Keyword
Remote control command “$”
Data set command “!”
Data output command: “?”
Each command consists of a keyword, three characters. Parameters are added when necessary.
Keyword
($/!/?) Char-1 Char-2 Char-3 Parameter…
An asterisk is added in front of the keyword when the extended command is to be used.
