The UNIGATE also supports the connection of applications or products, that communicate via
SSI.
6.1

Initiation of the SSI-interface

The required Script (example_SSI), the firmware- (Cust0023) and Protocol Developer-exten-
sion (Cust_ssi.xml) are available free of charge from our website at www.deutschmann.de, as
well as the softwaretool Protocol Developer and the configuration software WINGATE.
In the Protocol Developer (see chapter 7, The Debug-interface) the ConfigFile
•
"Cust_ssi.xml" has to be added. At Options
Load the Script "example_SSI.dss" into the Protocol Developer.
•
The encoder type and the clock frequency has to be defined in the Script itself under
•
"Set number of bits" and "Set type and clock stretch value" (default =
12-Bit-Single-Turn-Gray, max. clock stretch):
// Set number of bits
// 1..16 = Single Turn
// 17..32 = Multi Turn
moveconst (bNumBits, 12);
// MT SSI 4096 x 4096 = 16777216 = 0b1000000000000000000000000 => 24 bit
//------------------------------------------------------------------------------
// Set type and clock stretch value
// Type (low nibble):
// 0 = Reserved
// 1 = output value as is (i.e. binary encoder)
// 2 = convert Gray encoded output value to binary (i.e. Gray encoder)
// >2 = Reserved
//
// Clock stretch value (high nibble):
// Please note that the given frequency values are only a rough estimate. The
// exact frequency varies depending on the devices underlying architecture.
// 0 = No Stretch --> ~300 kHz
// 1 = ~185 kHz
// 2 = ~150 kHz
// 3 = ~125 kHz
// 4 = ~110 kHz
// 5 = ~100 kHz
// 6 = ~ 88 kHz
// 7 = ~ 80 kHz
// 8 = ~ 72 kHz
// 9 = ~ 67 kHz
// A = ~ 62 kHz
// B = ~ 58 kHz
// C = ~ 54 kHz
// D = ~ 50 kHz
// E = ~ 48 kHz
// F = ~ 45 kHz
