Rnet manual

[MotoRoland]

Hi, I have two Rnet modules, but have lost the manual.
Can anyone help with a manual (think its 6880901Z35) or just info on supply voltage. Is it a 12V product or does it follow what the batteries on an old Expo or P50 has?

1.2 RNET-SLM RADIOS

Although the RNet-SLM telemetry circuit boards are different from those of the RNet radios, the location of the tuning adjustments and DIP switches are located in the same places. The only difference between between the two types of radios (other than the packaging) is the removal of the the internal voltage regulator circuitry (U307, R345 and R346—refer to the Audio Board schematic diagram). The SLIMet generates 2 watts at VHF and UHF with 7.5 V dc input, and either 4 watts at UHF or 5 watts at VHF with 11.25 V dc input.

CAUTION
Do no apply more than 11.25 volts to the
unit to avoid damaging the transceiver.

Under section 2.2 Alignment Procedures

For RNet Units:

Step 2. Set the power supply output to 12.0 V dc for 2 watt units or 17.0 V dc for 4/5 watt units. {then the power supply is turned off and R345 -missing in the SLM- is adjusted for 7.5 V at 2 watts and 11.25 V at 4/5 watts.}

For RNet-SLM Units:

Step 3. Set the power supply output to 7.5 V dc for 2 watt units or 11.25 V dc for 4/5 watt units. ...

Obviously the internal regulator U307 allows the RNet to survive input voltages that would damage the RNet-SLM.

Since the EXPO and P50 have their own audio boards (where the voltage regulator on the RNet is located) these hand held radios would have their own unique voltage requirements.

You got the manual part number right.

The Systems 9000 Vehicular Repeater System (VRS) supplies the SLIMNET radio with 7.5 V dc and keyed 7.5 V dc.

Thanks, mine is the RNet 9600, so 12V will be OK.

Best to run those at 7.5v. Actually if it is the synthesized unit, the RF is basically a GP300. When the manual says DO NOT EXCEED 11.25v, they mean it. Since these radios are long ago NLA, best to be conservative and get that extra 3db from an antenna.
