dvmcfggen - Quick Reference

Installation

cd dvmcfg
pip install -r requirements.txt
# or just run ./dvmcfg (auto-creates venv)

Common Commands

Interactive Wizard

# Guided configuration (recommended for beginners)
./dvmcfg wizard
./dvmcfg wizard --type single    # Single instance
./dvmcfg wizard --type trunk     # Trunked system

Single Configuration

# Create from template
./dvmcfg create --template <name> --output <file> [options]

# Validate
./dvmcfg validate <file> [--summary]

# Edit value
./dvmcfg edit <file> <key> <value>

# List templates
./dvmcfg templates

Trunked Systems

# Create system
./dvmcfg trunk create --base-dir <dir> --vc-count <n> [options]

# Validate system
./dvmcfg trunk validate --base-dir <dir> --name <name>

# Update all configs
./dvmcfg trunk update --base-dir <dir> --name <name> <key> <value>

Quick Examples

Hotspot

./dvmcfg create --template hotspot --output hotspot.yml \
    --identity "HS001" --peer-id 100001 --callsign "KC1ABC"

P25 Trunk (4 VCs)

./dvmcfg trunk create --base-dir /etc/dvm/trunk \
    --protocol p25 --vc-count 4 --identity "SITE001" \
    --base-peer-id 100000 --nac 0x001

DMR Trunk (2 VCs)

./dvmcfg trunk create --base-dir /etc/dvm/dmr \
    --protocol dmr --vc-count 2 --color-code 2

Common Config Keys

network.id              - Peer ID
network.address         - FNE address  
network.port            - FNE port
system.identity         - System ID
system.config.nac       - P25 NAC
system.config.colorCode - DMR color code
system.config.siteId    - Site ID
system.modem.rxLevel    - RX level (0-100)
system.modem.txLevel    - TX level (0-100)
protocols.p25.enable    - Enable P25
protocols.dmr.enable    - Enable DMR

Templates

hotspot - Simplex hotspot
repeater - Duplex repeater
control-channel-p25 - P25 CC for trunking
control-channel-dmr - DMR CC for trunking
voice-channel - VC for trunking
conventional - Conventional with grants

File Structure

Single config:

config.yml

Trunked system (name: "test", 2 VCs):

test-cc.yml       # Control channel
test-vc01.yml     # Voice channel 1
test-vc02.yml     # Voice channel 2

Default Values

Parameter	Default	Notes
FNE Address	127.0.0.1	Localhost
FNE Port	62031	Standard FNE port
Base Peer ID	100000	CC gets this, VCs increment
Base RPC Port	9890	CC gets this, VCs increment
P25 NAC	0x293	Standard NAC
DMR Color Code	1	Standard CC
Site ID	1	First site
Modem Type	uart	Serial modem

Validation Checks

IP addresses (format and range)
Port numbers (1-65535)
Hex keys (length and format)
NAC (0-4095), Color Code (0-15), RAN (0-63)
Identity/callsign (length limits)
RX/TX levels (0-100)
Trunk consistency (NAC, CC, Site ID match)

Tips

✓ Always validate after creation/editing ✓ Use --summary to see config overview ✓ Test with --modem-type null first ✓ Keep peer IDs sequential ✓ Use trunk update for system-wide changes ✓ Backup configs before bulk updates
