Microcontroller With Ethernet Media Access Controller 10/100
2MB Serial Flash Memory IC
IRIG Isolation IC & Isolation Transformer
IRIG-B Demodulating Circuit
BNC Connectors for IRIG-B Input, 1PPS Output & 1PPS Input
RJ45 Connector (Ethernet Connection)
Mini Din Connector (Used by the factory for initial IP address and board setup)
Jumper Settings
JP1 – Jumper On =Normal Operating State
Jumper Off =Factory Debug Position
JP2 – Jumper Pins 1 to 2 =Modulated IRIG-B Input
Jumper Pins 2 to 3 =Un-Modulated IRIG-B Input
JP3 – Jumper Pins 1 to 2 = External 1PPS
Jumper Pins 2 to 3 = Internal 1PPS
Note: Internal 1PPS indicates that an IRIG-B signal has been connected to the DSP circuit board
(the 1PPS signal is part of the IRIG-B signal).
External 1PPS indicates the DSP circuit board is receiving a 1PPS signal from another
DSP circuit board or possibly from a clock 1PPS output.
J1 is used to connect an emulator. Under normal operating conditions. J1 must have four
jumpers in the following positions:
5 to 6
7 to 8
9 to 10
11 to 12
J2 is used by the factory to download a program to the microprocessor/Ethernet IC. During
normal operation J2 has no jumpers.
If the 1PPS signal is daisy chained from chassis to chassis via the input and output BNCs the
latency is 100ns per jump. Latency can be nearly eliminated by using a BNC “T” connector
and paralleling the 1PPS signal from input to input.
