DLP-G24 Install Timing Wires on the Backplane (ANSI Only)
Step 1 Using 100-ohm shielded BITS clock cable #22 or #24 AWG (0.51 mm² or 0.64 mm²), twisted-pair
T1-type, wrap the clock wires on the appropriate wire-wrap pins according to local site practice.
Ground the shield of the BITS input cable at the BITS end. For BITS output, wrap the ground shield of
the BITS cable to the frame ground pin (FG1) located beneath the column of BITS pins. Table 1-6 lists
the pin assignments for the BITS timing pin fields.
