1 Serial communication interface
1.1 Physical interface
a) DN-645/625 has a D-sub 9 pin female connector for serial interface.
b) Table 1 indicates pin assignment of connector signals . RS-232C and RS-422A can be selected with
software switch on the DN-T645. RS-422A is not available on the DN-T625, only RS-232C.

2 Command format and answer format
The DN-T645/625 uses commands each of which consists of a data row (some commands don't need PC) composed
of command codes (CC) and parameter codes (PC). The host shall be designed to send block check characters
(BCC) following ETX, with the data row enclosed in STX (text start: 0x02) and ETX (text termination: 0x03).
The DN-T645/625 shall complete command receive with correct BCC codes.
Here are the formats.
Commands <STX> <CC> <PC0> <PC1> <PC2> <………..> <PCn> <ETX> <BCCH><BCCL>
STX (Start of TeXt) 0x02
CC (Command Code) Command code
PC (Parameter Code) Number of parameters is defined for each command.
ETX (End of Text ) 0x03
BCC (Block Check Character) CC + PC0 + PC1 + PC2 + + PCn + ETX = XY (hex)
Each of X and Y is 4 bit long, X, Y=0,1,2,3,4,5,6,7,8,9,A, B, C, D, E, F
BCCH is an ASCII code converted from X (higher 4 bits of sum) and BCCL is converted from Y (lower 4 bit of sum).
BCCH and BCCL are ASCII coded data. If a three digit check sum is calculated, ignore the hundredths place.
Answers<STX> <CC> <AC> <PC0> <PC1> <PC2> <> <PCn> <ETX><BCCH><BCCL>
STX (Start of TeXt) 0x02
RC (Reply Code) Reply code (=Command code)

PC (Parameter Code) Number of parameters is defined for each command.

Each of X and Y is 4 bit long, X, Y=0,1,2,3,4,5,6,7,8,9,A, B, C, D, E, F

BCCH and BCCL are ASCII coded data. If a three digit check sum is calculated, ignore the hundredths place.

2.1 Protocol for data transmission and reception
This device’s serial protocol is based on half-duplex communication. Therefore the host shall transmit
commands and receive answers according to the following procedure.
Basic procedure
1) The host selects a preferred command and transmit s codes to the device. The host shall not send each
byte within 40µsec because the device cannot receive within 40µsec after previous byte.
2) The host shall wait for the device’s answer before transmitting the next command. Reading RC, AC
and PC bytes, the host can get acknowledge whether the device received previous command correctly or not.
3) When transmitting a command which causes some function, the host shall get device’s status that the
device becomes ready. The Read Status command is used for this purpose.
4) The host shall complete the transmission of one command within 40 msec.
5) The device shall return answer within 5 seconds.
6) The device cannot receive any command within 2 second after the power is turned on.
Communication errors
1) In case of a communication error such as overrun, framing, or parity error, the device returns a NAK
(15h) code within 80ms ec from the start of command transmission. When a NAK (0x15) code is received,
the host shall transmit the previous command again immediately.
2) If the host detects communication error while receiving the answer, the host shall send a NAK (0x15)
code within 80ms ec from beginning of receipt. The device sends the same answer again after receiving
a NAK code within 80msec.
3) The host shall send the previous command when there is no answer from device.
