3.1.7 TM-1300 RS-232C Control
The TM-1300’s built-in microcomputer chip (CPU) can be controlled by an external RS-232C interface.
The internal CPU controls TM-1300 operation mode and DSP parameter changes. Contact PULNiX for
the TM-1300 software diskette.
3.1.7 (a) RS-232C Communication Default Condition
Parity:
None
Data:
8-bit
STOP:
1-bit
Baud rage:
9600 bps
If other communication conditions are required, please contact PULNiX.
Note:
The TM-1300 protocol requires no handshaking.
3.1.7 (b) RS-232C Command
The TM-1300 command package begins with “.” (Start of Text = 3AH), and is then followed by the
Command Code (C.C. ..one alphabet), Command option parameter and CR (End of Text = 0DH) to end.
When a packet is received by the TM-1300 (ETX:03H is detected), it reads the internal packet of the
receiver buffer. If it is the correct packet, then it processes the parameters based on the command. When
the process is completed, it sends a completion signal (AK packet). If an error is detected, a No-go
signal (NK packet) is sent back and it disregards the packet signal in the buffer. When an NK packet is
sent from TM-1300, the host must correct the error and resend the packet.
Example: Executing manual shutter control #2.
The C.C. packet is sent as follows:
“:”, “S”, “M”, “2”, CR
3AH, 53H, 4DH, 32H, 0DH
where “S”.....Shutter control command mode
“M”.....Manual mode
