- 2. Digital - SSi Interface (absolute position) DL-25 Sold & Serviced By: Synchronous Serial Interface (SSi) allows for serial transmission of absolute position data from the Electric Encoder™ responding to controller clock pulses. The Encoder and controller are linked by clock and data differential signal lines. n = total number of data bits. T = clock period (sec) - user defined. 1/T = clock frequency 0.5 ÷ 2.5 MHz (user defined). t1 = minimum time required for the encoder to freeze data and preset the shift registers before receiving the first rising edge to prompt the MSB t2 = data transmission delay (increases with cable length) t3 = required delay to refresh position data between subsequent position reads. - 2 - Output signal parameters Signal latency ~250 μSec Output code Binary Serial output SSi Differential RS-422 Clock SSi Differential RS-422 Monoflop time 25 μSec Clock Frequency 0.5 ÷ 2.5 MHz Position update (Max) 30KHz SSi - Wires color code # Name Color Function 1 Clock + Grey SSi Clock 2 Clock - Blue 3 Data - Yellow SSi Data 4 Data + Green 5 GND Black Ground 6 +5V Red Power supply Electric Encoder Explorer (windows XP / 7) Provides set of tools for configuration , (BIT) Build in tests - setup , Zero (index) definition.
