The PV-1800 has an onboard DC/DC converter that converts the incoming mains (+8-35V DC) to +5V. This power supply delivers +5V, up to 4A, to the PV-1800 and to the PC/104 bus. A mains fuse F2 (1.6A) is placed on the rear side of the PCB, near KL1. In PV-1800A versions, where the DC/DC-converter is omitted, the module receives its power from the PC/104 bus.

The GSM modem is placed on the top side of the PCB while the SIM card connector is placed on the rear side. The locking mechanism is indicated on the top of the SIM card holder. The connector for the antenna is placed on the GSM modem itself. The base address of the PV-1800 registers and COM ports, and IRQs for the modem and the COM port on CN6, are set by two jumper blocks. The analogue section (PV-1800 only) is available in different configurations including pure voltage inputs (0-2.5V, 0-5V and 0-10V), pure current inputs (0-20mA) and with mixed inputs (0-2.5V and 0-20mA). The configuration must be decided when ordering – see section ordering codes.

The digital I/O section is found on all models except PV-1830 versions.
