Budget digital two-way with analogue fallback: DMR Tier II TDMA doubles 12.5 kHz capacity to two simultaneous voice paths, 32-channel memory, IP55 dust/water ingress rating, -30°C to +60°C operating range, VHF/UHF frequency bands.
Intrinsically safe analogue portable certified ATEX II 2G Ex ib IIC T4 (Zone 1 gas + Zone 21 dust): 16-channel analogue memory, IP67 ingress protection, restricted power budget enforced by Ex ib energy limits for oil, gas and petrochemical atmospheres.
Capacity: CP200d DMR Tier II TDMA delivers 2 voice paths per 12.5 kHz channel vs 1 analogue path on GP340Ex — same licensed spectrum, double the talk groups.
Compliance: GP340Ex Ex ib IIC T4 is the only legal route into Zone 1 explosive atmospheres; CP200d (IP55) has no hazardous-area certification at all.
Selector: Non-hazardous budget digital migration → CP200d (spectrum-efficient, mixed digital/analogue fleet); oil, gas and chemical plants → GP340Ex (intrinsic safety is the entry ticket, closed analogue workgroup is acceptable).
