10.0 Repeat Panel Wiring
The 3300 can drive up to eight 3300 Repeat Panels directly from its External Expansion Interface port.
No extra driver boards are required.
The external expansion port has four connections, present on a terminal block labelled
‘EXT EXP’ on the Main PCB. These are:
1. +24V (fused at 100mA, self resetting (when overload and power is removed), non-monitored)
2. 0V
3. Data -
4. Data +
This port connects to all Repeat Panels and should be wired in screened cable to ensure compliance
with relevant EMC regulations. Figure 10.0 shows a typical installation.
