Operation
3.3.7 (b) RS-232C Control Commands
External RS-232C (or optional RS-485) computer control allows the operator to remotely adjust the following functions: clock speed, shutter, gain, A/D reference and scan format. The control commands are detailed below.
Note: RS-232 control will override the rear panel switch control. (TM-6710 only)
The TM-6710 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-6710 (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 the TM-6710, 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 | | |
The TM-6710 will send back | | |
“:”,ACK,CR | or | “:”,NAK,CR |
3AH, 06H, 0DH | | 3AH,15H,0DH |
Command S
Function: Shutter control command. Shutter mode selection and shutter speed setting.
1.Manual Shutter Mode
“:”, “SM”, “0” - “9”, CR
3AH, 53H, 4DH, 30H - 39H or 53H, 0DH
Enables manual shutter operation. Select 0 through 9 shutter speed. This overrides the back panel setting. When “S” code is selected, the back panel shutter switch is activated for speed selection.
2.Async Shutter Mode
“:”, “SA”, “0” - “9”, CR
3AH, 53H, 41H, 30H - 39H, 0DH
3.Direct Shutter Mode
“:”, “SX”, “1A0”, CR
3AH, 53H, 58H, 31H, 41H, 30H, 0DH
