KRAMER: SIMPLE CREATIVE TECHNOLOGY

Kramer Protocol 2000

NOTE 4 - The reply to a "REQUEST" instruction is as follows: the same instruction and INPUT codes as were sent are

returned, and the OUTPUT is assigned the value of the requested parameter. The replies to instructions 10 and 11 are as per

the definitions in instructions 7 and 8 respectively. For example, if the present status of machine number 5 is breakaway

setting, then the reply to the HEX code

would be HEX codes

NOTE 5 – For the OUTPUT byte set as 6, the VIS source is the input selected using the OUTPUT byte. Similarly, for the

OUTPUT byte set as 7, the VIS source is the output selected using the OUTPUT byte. Note also, that on some machines the

sync source is not software selectable, but is selected using switches, jumpers, etc!

NOTE 7 – Setting OUTPUT to 0 will return the VIS source setting as defined in instruction #7. Setting to 1 will return the

input # or output # of the sync source (for the case where the VIS source is set as 6 or as 7 in instruction #7). Setting to 2

returns the vertical sync frequency (0 for no input sync, 50 for PAL, 60 for NTSC, 127 for error).

NOTE 8 - The reply to the "REQUEST WHETHER SETUP IS DEFINED" is as in TYPE 3 above, except that here the

OUTPUT is assigned with the value 0 if the setup is not defined; or 1 if it is defined.

NOTE 9 - An error code is returned to the PC if an invalid instruction code was sent to the switcher, or if a parameter

associated with the instruction is out of range (e.g. trying to save to a setup greater than the highest one, or trying to switch an

input or output greater than the highest one defined). This code is also returned to the PC if an RS-232 instruction is sent

while the machine is being programmed via the front panel. Reception of this code by the switcher is not valid.

NOTE 10 – This code is reserved for internal use.

NOTE 11 – For machines where the video and / or audio gain is programmable.

NOTE 12 - Under normal conditions, the machine's present status is saved each time a change is made. The "power-down"

save (auto-save) may be disabled using this code. Note that whenever the machine is turned on, the auto-save function is set.

NOTE 13 - This is a request to identify the switcher/s in the system. If the OUTPUT is set as 0, and the INPUT is set as 1, 2,

5 or 7, the machine will send its name. The reply is the decimal value of the INPUT and OUTPUT. For example, for a 2216,

the reply to the request to send the audio machine name would be (HEX codes):

81 (i.e. 128dec+ 22dec for 2nd byte, and 128dec+ 16dec for 3rd byte).

If the request for identification is sent with the INPUT set as 3 or 4, the appropriate machine will send its software version

number. Again, the reply would be the decimal value of the INPUT and OUTPUT - the INPUT representing the number in

front of the decimal point, and the OUTPUT representing the number after it. For example, for version 3.5, the reply to the

request to send the version number would be (HEX codes):

81 (i.e. 128dec+ 3dec for 2nd byte, 128dec+ 5dec for 3rd byte).

If the OUTPUT is set as 1, then the ASCII coding of the lettering following the machine’s name is sent. For example, for the

VS-7588YC, the reply to the request to send the first suffix would be (HEX codes):

81 (i.e. 128dec+ ASCII for “ Y” ; 128dec+ ASCII for “ C” ).

NOTE 14 - The number of inputs and outputs refers to the specific machine, which is being addressed, not to the system. For

example, if six 16X16 matrices are configured to make a 48X32 system (48 inputs, 32 outputs), the reply to the HEX code

82 (ie. request the number of outputs)

would be HEX codes

i.e. 16 outputs

NOTE 15 – When the OVR bit (4th byte) is set, then the “ video” commands have universal meaning. For example,

instruction 1 (SWITCH VIDEO) will cause all units (including audio, data, etc.) to switch. Similarly, if a machine is in

“ FOLLOW” mode, it will perform any “ video” instruction.

NOTE 16 - The reply to the “ REQUEST WHETHER PANEL IS LOCKED” is as in NOTE 4 above, except that here the

OUTPUT is assigned with the value 0 if the panel is unlocked, or 1 if it is locked.

NOTE 17 – Delayed execution allows switching after a delay dictated by RS-232. To do this, the user sends instruction 7

with the “ Set for delayed switch” option (64dec) before sending the switch command (instruction 1) or pressing via front

panel. The switch is not executed (unless timed-out) until the “ Execute delayed switch” code is sent, or the “ “ Set for delayed

switch” code is sent again. (The mode is automatically cancelled after implementation of the switch if the “ execute”

command is used).

For example, to connect input 4 to output 3 after a delay, send HEX codes

(set for delayed switch)

(switch code)
