5.6 Setting node addresses
In the FR2AV, 2RU frame the node address is calculated in one of two ways:
•
slot number minus 1 – giving a range of 0 - 11 in frame #1,
OR
•
slot number plus fifteen – giving a range of 16 – 27 in frame #2
The two ranges are provided to allow one control panel to control two frames.
ADC104 Node Address jumper/selector
S1 is normally set to position 0 (factory default). If the ADC104 card is used in older
frames such as FR2-12 or FR1-6 and these frames are being used with an active front
panel then the Hex switch S1 can be used to set the node number (0 to 15) of the card.
Note no two cards in a frame should have the same node number.

Node address setting
FR2AV,
FR1AV,
DTB2-AV
Set node switch, S1 to ‘0’ and set link J10 in position 2-3. Altering J10 may cause
incorrect node addressing on this and other boards in an FR2AV frame.
FR1-6
FR2-12
FR2-8
Set the remote node address in conjunction with link J10 as follows:
J10 2-3 – set node addresses from 0 to 15 with S1
J10 1-2 – set node addresses from 16 to 31 with S1 (16 is added to switch setting)
The node address setting is only read on power up.
5.7 Software upgrades
The software for the ADC104 module is contained in a single EPROM U32. To change
this, remove the board from the frame and lever out the EPROM using an IC extraction
tool or small flat bladed screwdriver. Replace the EPROM making sure that the notch on
the IC faces away from the rear connector.
