NOTES on the above table:

NOTE 1 - When the master switcher is reset, (e.g. when it is turned on), the reset code is sent to the PC. If this code is

sent to the switchers, it will reset according to the present power-down settings.

NOTE 2 - These are bi-directional definitions. That is, if the switcher receives the code, it will perform the instruction; and

if the instruction is performed (due to a keystroke operation on the front panel), then these codes are sent. For example,

if the HEX code

01

85

88

83

was sent from the PC, then the switcher (machine 3) will switch input 5 to output 8. If the user switched input 1 to output

7 via the front panel keypad, then the switcher will send HEX codes:

41

81

87

83

to the PC.

When the PC sends one of the commands in this group to the switcher, then, if the instruction is valid, the switcher

replies by sending to the PC the same four bytes that it was sent (except for the first byte, where the DESTINATION bit

is set high).

NOTE 3 - SETUP # 0 is the present setting. SETUP # 1 and higher are the settings saved in the switcher's memory, (i.e.

those used for Store and Recall).

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

0B

80

80

85

would be HEX codes

4B

80

81

85
