PC/104 Bus  
All models, except A-versions, 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 module and to the PC/104  
bus. A mains fuse F2 (1.6A) is placed on the rear side of the PCB, near KL1. In A-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 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, PV1700 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.

Differential measurement  
The analogue inputs can two by two be used for differential measurement. Inputs, which can make  
up a pair, are defined in the software. One of the wires, in each pair, is inside the ADC connected as  
a ‘negative’ input; the other as a ‘positive’ input. The common mode voltage on the ‘negative’ input  
must not exceed 0.5V in a 0 – 2.5V configuration and 1V in a 0 - 5V configuration. The  
combinations of the actual inputs used for differential measurement are shown in section - PV-1800  
register interface. Also here it is described which input that is used as the ‘negative’.

REG_SIGN (base+0): Signature (read only)  
Always reads 8Ch. Can be used by software to verify the presence of a module with register  
interface.  
REG_MODEL (base+1): PV-1800 firmware model number (read only)  
When the firmware is changed to remove, add, or change features, the model number is  
changed. Current model number is 00h.  
REG_DIGOUT (base+2): Digital outputs (read/write)  
Writing to bit 0-6 sets digital output 0-6. 0=off, 1=on.  
Reading bit 0-6 returns the current status of digital output 0-6.  
Bit 7 is always 0.  
REG_DIGIN (base+3): Digital inputs (read only)  
Reading bit 0-7 returns the current status of digital input 0-7. 0=off, 1=on.  
DI0 and DI1 can also be used as counter inputs. Regardless of this, their current  
status can always be read at this register.  
REG_CNTLO (base+4): Counter low byte (read only)  
Reading this register returns bit 0-7 of the current value of the counter, and  
simultaneously stores bit 8-15 of the counter in the REG_CNTHI register.  
REG_CNTHI (base+5): Counter high byte (read only)  
Reading this register returns the previously stored value of bit 8-15 of the  
counter.

REG_CNTMODE (base+6): Counter configuration (read/write)  
The counter starts at 0000h after system reset. It cannot be reset or reloaded from software.  
Bits: 000000cc  
cc = counter mode (read/write):  
00 = counter disabled, DI0 and DI1 are ignored  
01 = counts rising edges of DI0  
10 = counts falling edges of DI0  
11 = quadrature counter on DI0 and DI1  
REG_MODEM (base+7): Modem status and on/off control (read/write)  
Bits: 00000vlo  
v: (read only) 1 = VIO voltage (2.75V) on, 0=off.  
l: (read only) Modem LED status. 0=LED off, 1=LED on.  
o: (read/write) Force on/off. Writing '1' to this bit pulls the modem on/off pin  
low. To turn the modem on or off, you should write '1' to this bit, wait at  
least two seconds, and then write '0' to this bit.  
The module has logic that automatically turns the modem on at system reset.  
REG_UPS (base+8): UPS status (read only)  
The UPS status inputs have no other function than being readable here.  
Bits: ab000000  
a: UPS status1 input from external UPS logic  
b: UPS status2 input from external UPS logic  
REG_UPSSHDN (base+9): UPS delayed shutdown timer (read/write)  
This register holds the number of seconds until the external UPS logic is told to  
turn off power.  
The UPS_PWROFF output is low (0V) when the system should run normally, and high (3.3V)  
when external UPS circuitry should turn off power.  
FFh: Idle, no delayed shutdown is in progress. UPS_PWROFF is low.  
00h: Delay expired, UPS_PWROFF is high.  
Other values: Delay in progress, the counter decrements towards 00h. UPS_PWROFF is low.  
A delayed shutdown is initiated by writing the desired number of seconds to this  
register. A delayed shutdown in progress can be modified (by writing a new value  
to this register), cancelled (by writing FFh), or you can turn off immediately by  
writing 00h.

REG_ADCLO (base+0Ah): ADC command, status, and result low byte (read/write)  
Writing to this register starts a new A/D conversion. You should only do this  
when the ADC is idle.  
Command bits: 0000dccc  
d: 0:single-ended, 1=differential  
ccc: Channel.

1 1 0 1 Differential AIN5(-) - AIN4(+)  
1 1 1 0 Differential AIN6(+) - AIN7(-)  
1 1 1 1 Differential AIN7(-) - AIN6(+)  
Reading REG_ADCLO returns status and result bits.  
Result bits: rrrr00pb  
p: ADC present. If 1, the ADC is available. If 0, the ADC is not mounted, and  
you should not write to REG_ADCLO.  
b: Busy. 0 = ADC idle. The previous result can be read, and a new conversion can  
be started. 1 = conversion in progress. All result bits are invalid when b=1.  
rrrr: Four least-significant bits of the conversion result. Only valid when b=0.  
REG_ADCHI (base+0Bh): ADC result, high byte (read only)  
Reading this register returns the eight most-significant bits of the conversion  
result. Only valid when the ADC is idle.
