for zones 25 to 48, etc. Each RAM-2944-8 and AGD-2944-8 controls 8 zones. Up to 3 RAM-
2944-8s or AGD-2944-8s can be chained together to provide up to 24 zones per chain. Each
RAM-2944-8 will require a jumper for addressing (see below). No jumpers are set on the
AGD-2944-8 for addressing purposes.
The AGD-2944-8 LED Driver has a 50 pin connector for connection to the LEDs. The LEDs
are wired to a 50 pin socket which the AGD-2944-8 plugs into. The pin-outs are shown in
Figure 3.
2.2.5 RAM-2944-8 Jumper Settings
The jumpers for setting the octet are located just below the ribbon cable connector (see Figure
4). There are three pairs of holes. Soldering a wire jumper across the required pair will set the
RAM-2944-8 to be the first, second or third octet. There is a trace on the board jumpering the
pair for the first octet. This will need to be cut if the board is for the second or third octet.
Attention: Do not use P11 for LEDs. This will cause damage to both the RAM-
2944LCD and the LED driver.
