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 2-13.
