CONNECTOR PIN-OUTS; INTERCONNECT INFORMATION
Connector pinouts for the frame and panel D connectors are listed below.
Connections to the devices are standard RS-422 links.
The connection between the frame and control panel is also RS-422, but includes
power for the control panel. All 9 pins (of the D-9) must be connected, and the
maximum length using #22 conductors is 150’. If the panel must be extended
beyond this length, it should be locally powered. Contact Lance Design for details.
