The window based limits can also be set to output a TTL logic level at the
rear panel Rmt I/O port when the predefined limits are exceeded. You can
switch the rear panel TTL outputs on or off; set the TTL output level to
active high or low; and determine whether the TTL output represents an
over limit condition, under limit condition or both.
The TTL connector is an RJ-45 series shielded modular jack assembly
with the TTL output pins connected as shown in Figure 2-14.
