Factory settings for RS-232 9600,N,8,1
Network Port 10/100
The Ethernet port interface is:
Type: Standard RJ-45 8 pin connector, 10 Base-T and 100 Base-T standards.
Frame format: IEEE 802.3
J1 - Optional TI/ET
The TI/ET configuration is via the Keypad, Serial I/O, and Network port. J1 accepts an
external 1 PPS or Event input signal and measures it against the system-derived time. The
minimum pulse width of the input signal is 100 nS. The input impedance is selectable at 100
kW or 50 W. The rising edge of the pulse is measured with 5 nS resolution relative to the
system clock time.
Pulse width: 100 nS, min.
Active Edge: Rising
High Level: Logic Hi >1.25 V < 10 V
Low Level: Logic Low < 1.25 V >0 V
Impedance:
100 kW or 50 W
Resolution: 5 nS, single shot
Accuracy:
