24 SP-1G - Kramer Protocol 2000
8 Kramer Protocol 2000
Protocol 2000 for the
SP-1G
is described below. For RS-232, data is at 9600
baud, no parity, 8 data bits, and 1 stop bit. All values shown are hexadecimal.

Parameter Addresses
There are global parameters that are invariable in the case of a setup number change, and local parameters that have
appropriate E values for each setup number (16 different values, stored in special memory). During write or read operations
with local parameters, the PC gets access only to the active local parameter that corresponds to an actual setup number.
Certain local parameters (not all) are represented in two-byte format because of their large adjustment. To distinguish
between one-byte and two-byte parameters, as well as global and local parameters, the hex address of any parameter
(value "D"), contains a two-byte format flag – D7 (MSB) and a local parameter flag – D6.
All global parameters have the one-byte format, therefore their addresses (D7 = 0, D6 = 0) do not exceed 0x3f(hex) or
63(dec). One-byte local parameters (D7 = 0, D6 = 1) have addresses greater than 63(dec), but less than 128(dec). Two-
byte local parameters (D7 = 1, D6 = 1) have addresses greater than 192(dec). Note that while writing or reading two-byte
parameters (PC -> machine), you must send two consecutive write or read commands (each command having a
conventional 4-byte structure) for low (first) and high bytes with a minimal time interval between them.
