| There is an internal 5v0 rail but it is unsure if that can supply continous current for running the Raspberry Pi. One solution is to use a DC/DC converter powered by the 24V input. A Mean Well SD-15B-05 is a good choice. The case fits exactly into the small slot aside from the exciter unit. You just have arrange some wires to the backplane of the Base Station Controller board. There are some free pins that can also be used for the ethernet connection of the Raspberry Pi. It can be mounted with two 3mm screws to the side of the case. That should also allow for some heat dissipation. | There is an internal 5v0 rail but it is unsure if that can supply continous current for running the Raspberry Pi.

| There is a RJ45 jack on the backplane of the C9000. It was formerly used to connect a landline telephone connection to the transmitter, so it could make a call if something bad had happend. There is a way to re-use this jack to bring an 100 MBit/s ethernet connection inside the C9000 without mechanical modification of the housing. | There is a RJ45 jack on the backplane of the C9000.

| + | ==== Front Panel LEDs ===== | ||
| + | |||
| + | You can wire two LEDs to the RasPagerC9000 board that can be integrated into the front panel. The wires need to be connected to pins 5,6,7 of RasPagerC9000. The pinout is as follows: | ||
| + | |||
| + | * Pin 5: GND | ||
| + | * Pin 6: SWAct | ||
| + | * Pin 7: MasterConn | ||
| + | |||
| + | {{ :c9000:c9000leds.png?nolink&600 | Pinout for Fron Panel LEDs}} | ||
| + | |||
| + | These LEDs indicate if UniPager is connected to the Master (MasterConn) and when its active (SWAct). The corresponding LEDs are not controlled by UniPager directly. You have to use the extra python script called unipagerled.py. It is sufficient to use the preset from the example in the config (/etc/unipagerledconfig.py): | ||
| + | |||
| + | preset = "c9000" | ||
| + | |||
| + | Two resistors (330R) are already present on the PCB (see R10 and R11). The two LEDs can be mounted on the fron panel of the Base Station Controller. | ||

| The RasPagerC9000 PCB is already prepared for easy implementation of a temperature monitoring of the C9000. It is done by cheap DS18x20 OneWire temperature sensors.
