Panasonic AG-5700 - Command Interval Requirements

STI
w Send command and reply data from the VTR
When a command is sent correctly, the format data of 1) described in the “(3) Receive format" (page 17) is sent
back, however the VTR does not necessarily perform the operation specified by the command, even if it responds to
the format of 1). For example, if the playback command “[STX]OPL[ETX]" is sent when the power to the VTR is OFF,
[STXJOPL{ETX] will be returned from the VTR, however because the power is OFF, playback wiil not take place.
In such a case, the state of the VTR can be checked by using the VTR status sense command ([STX]QOP[ETX)).
\f one of the following mistakes is made, an error code will be returned, and a certain amount of time will be
necessary to search for the cause, so be very careful.
1. Failure to insert a blank
Example:
[STX}]SCS:1425123[ETX]
In this example, the operator intended to input a command that would search for 1
hour, 42 minutes, 51 seconds, 23 frames and display a STILL picture. When searching
in the positive direction, be sure to insert a space after “:”. The correct input is as
follows.

Blank
2. When the data exceeded the allowable range
Example:
{STX]SPT:_1 aid S[ETX)
- The data for “second” unit in this example is 70, hence it is incorrect.
Be sure to input data within the range 0 to 59.
3. When the next command is sent, a limit will be imposed on the commands that can be accepted until the
completion of processing. Note that apart from when the special commands shown in the table below (commands
that interrupt processing) are being executed, an error code will be returned.

B interval between the previous send command and the next send command
The AG-5700 is a multi-microcomputer VTR. A command that is to be processed in some way by the system control
microprocessor in the VTR requires time (approx. 150 msec) to be transmitted between the RS-232C interface
microprocessor and the system control microprocessor. The commands indicated below are used to perform
processing in the system control microprocessor, so allow an intervals of at least 150 msec when sending a
command from the personal computer. When sending the same command such as when sending the ORW
command in order to perform a REVIEW operation, send it continuously.
