Control Port Connectors
The master control frame has two sets of these connectors — one for the primary control card and
one for the redundant control card.
CTRL1, CTRL2 DIAG
Router Control Card
At the front of the EM0374 router control card is a DE9 diagnostic port:
An alternative to the 9-pin diagnostic port is the Phoenix 3-pin “console” port immediately above
it. Note that GND is at the top and Tx is at the bottom of the Phoenix connector. (The pins are
labelled on the PCB.)
On the DE9, pins 1, 4, and 6 are tied together and pin 9 is not connected.
