The IRIG-B Input Adapter (GE part number 520-0211LF) plugs into a dedicated IRIG-B slot
(slot 9) on the D400. The IRIG-B Input card accepts an IRIG-B signal in one of three input
formats through a corresponding connector type:
• Modulated IRIG-B through a BNC connector J2
AM modulated input accepts B12X, however, the SBS (straight binary seconds) in B120,
B124, and B127 are decoded but not used to set the time
