2. Fit the A1619 panel repeater interface to headers J3 and J5 on the A1579 panel
motherboard (J2 and J3 on A1638). The board should be held in place by a 12mm
high plastic spacer.
3. Connect the panel repeater RS485 wiring as shown in Figure 3.
Notes:
1.
Use only RS485 shielded data cable.
2.
Do not connect the cable shield to earth.
4. If the panel repeater is to be powered from the panel connect the 28V auxiliary
output from the motherboard to the A1575 repeater display. This is also shown in
Figure 3.
