Receiver Description
that the 12 V DC will be available only when the receiver is
powered from and external source, and not solely from its
internal battery.
On port A, the 1PPS output is similar to a standard TTL
output (0/+5 V):
• VOH Min= 4.5 V at IOL = - 4 mA
• VOH Max= 0.4 V at IOL= - 4 mA
Port B consists of the following:
• 1 x RS232 output, electrically similar to that on port A
• 1 x Event input with the following characteristics:
• VIH Min = 3.7 V
• VIL Max = 1.6 V
Port F provides an RS232 interface, electrically similar to
that on port A.
Multi-Function
Serial Cable
In the basic supply of the ProFlex 800 CORS station, this
cable (P/N 702450) comes with bare wires at one end.
It is also available as an optional cable (P/N 702443) with a
DB15 standard connector instead of bare wires.
