3.1.1 DIP Switches
With the front panel remov ed, DIP s witch 1 and DIP s witch 2 are visib le. These tw o
ten-position DIP switches configure and define many functions of the CM9760-
VCRC.
3.1.1.1 DIP Switch Locations
Figure 3 identifies the relativ e locations of DIP switches 1 and 2.
3.1.1.2 DIP Switch Functions
DIP switch functions are discussed in Section 3.3, SETUP.
3.1.2 LEDs
The green POWER LED located on the left front panel of the unit comes ON at
power up.
The red D ATA LED located on the right side of the front panel continually flashes on
and off at a regular rate (about 1/2 second intervals) until the first v alid command is
received. The LED will not flash again until another valid command is received.
Also, in cascaded situations, if a command is meant for a VCRC further down the
chain, the command will be relayed down the chain and the LED will not come on
until the appropriate VCRC processes the command. In other words, LED activity is
address specific. Additionally, if power is cycled, or if the DIP switch slide positions
are moved, or if a front panel reset occurs, then the LED will again flash intermit-
tently until the first valid command is received.
