Program 76-2X-Z: Assigns each installed TSIU port to operate at a specified transmission rate. 
Where X identifies the TSIU Port number (1, 2). Z identifies the TSIU/port transmission rate in 
bits-per-second (bps):
©Z=1; 9600
©Z=2; 4800
©Z=3; 2400
©Z=4; 1200
NoteThe sum of TSIU port 1 and port 2 bps rate cannot exceed 9600 bps.

DK40i Secondary Protection
The following diagram (see Figure 3-24) shows where secondary protectors must be installed for 
outside wiring.
Figure 3-24 DK40i Secondary Protector Diagram
Important!To protect against transient voltages and currents, solid state secondary protectors 
must be installed if there is outside wiring, and on all DID and E&M Tie lines. 
These protectors, which contain fast semiconductors in addition to fuses,...
