Subrack Data Ports
When using two or three HMX32128 subracks, use ports 1, 2, and 3 respectively on the
HMXAT200 system controller. The default baud rate for the subrack is 19.2K, but can be
changed to 9600bps using DIP switch 4, position 8 on the HMX128 controller card.
Alarm Detection Mode
If the optional HMX4248 I/O board is installed, the alarm detection mode is selectable
between contact closure mode and end-of-line resistor mode via
SW3, position 4.
OFF = contact closure mode
ON = end-of-line resistor mode
Pan/Tilt Protocol Selection
DIP Switches SW1 and SW2 on the HMX128 card are used to define the pan/tilt protocol
on control output ports 1-8. SW1 defines the protocol for ports 1-4. SW2 defines the
protocol for ports 5-8.
