Quartz Q256-SV System Manual
MANUAL-08
Serial Port Diagnostics (cmd: InterfaceDump x)
Where x is the number of the serial comms interface at the rear (counts from 0). NOTE: all telnet commands
use data for serial port 0 (eg monitor output destinations).
When using this command it is important to understand the comm port numbering scheme. The rear control
module PCI bus is numbered from slot 0 for the lower module position to slot 3 for the upper (Ethernet)
module position. The lowest installed RS422 or Q-Link module will be comm port 0.
Note that for this command numbering is from 0 but commssetup numbering is from 1. Great care must be
exercised when comparing interfacedump output with commssetup input.
For a typical installation this will give:
PCI Slot

Port Numbers
3 Ethernet

Note that the RS422 module has three RS422 ports (4, 5, 6 in the example above)
and an un-used 4
