The reco
corder output is
s a programmable analog ooutput. The rec
corder output voltage
is a funcction of the pre
essure on the sensor. The rrelation betwe
een the pressu
ure and
the volta
age is called the characteris
stic curve of thhe output.
Fundam
mentally we ha
ave to distinguish between loogarithmic and linear characteristic
curves:
•
garithmic charracteristic curv
ve is useful if tthe pressure range
r
covers several
s
A log
orde
ers of magnitude in the measurement. In tthis case it is appropriate to
o take
the llogarithm of th
he pressure an
nd then scale the result in a suitable manner.
•
A lin
near characterristic curve is useful
u
if the prressure range covers only a few
orde
ers of magnitude in the measurement. In tthis case the recorder
r
outpu
ut
volta
age is proportiional to the pressure value. You can spec
cify which presssure
valu e will result in the maximum
m output voltagge.
The ava

5 Communication Protocol (Serial Interface)
The VGC50x communicates with a computer via virtual serial interfaces (COM
ports). Thus the user software can access the VGC50x via USB Type B or via
Ethernet interface.
Communication via USB Type B
interface
The corresponding driver for the virtual COM port is installed automatically, when
the VGC50x is connected to a computer via the USB Type B interface. If the driver
is not installed automatically, it can be downloaded from the FTDI website
(www.ftdichip.com/Drivers/VCP.htm).
The installed virtual COM port appears as additional serial interface in the device
manager of the computer.
Communication via Ethernet
interface
With the Ethernet Configuration Tool a virtual serial interface (COM) can be assigned to an IP address. In addition, it allows configuration of the Ethernet interface
via a computer (→  105).
The installed virtual COM port appears as additional serial interface in the device
manager of the computer.
When the VGC50x is put into operation, it starts transmitting measured values in
intervals of 1 s. As soon as the first character is transferred to the VGC50x, the
automatic transmission of measured values stops. After the necessary inquiries or
parameter modifications have been made, the transmission of measured values
can be started again with the COM command (→  69).
Communication structure and procedures are identical for the three controllers
VGC501, VGC502 and VGC503. Therefore the term VGC50x is used in this
chapter.
It should be noted that mnemonics with channel specific parameters must be
issued with the number of values corresponding to the number of channels of the
respective device.
Example:

Transmit: OFC [,a]
VGC502
Transmit: OFC [,a,b]
VGC503

5.1 Data Transmission
Data format
Definitions
The data transmission is bi-directional, i.e. data and control commands can be
transmitted in either direction.
1 start bit, 8 data bits, no parity bit, 1 stop bit, no hardware handshake
The following abbreviations and symbols are used:

Data transfer from HOST to VGC50x
Data transfer from VGC50x to HOST
After each ASCII string, the HOST must wait for a report signal (<ACK><CR><LF>
or <NAK> <CR><LF>).
The input buffer of the HOST must have a capacity of at least 32 bytes.

5.2 Communication
Protocol
Transmission format
Messages are transmitted to the VGC50x as ASCII strings in the form of mnemonic
operating codes and parameters. All mnemonics comprise three ASCII characters.
Spaces are ignored. <ETX> (CTRL C) clears the input buffer in the VGC50x.

When requested with a mnemonic instruction, the VGC50x transmits the measurement data or parameters as ASCII strings to the HOST.
<ENQ> (CTRL E) must be transmitted to request the transmission of an ASCII
string. Additional strings, according to the last selected mnemonic, are read out by
repetitive transmission of <ENQ>.
If <ENQ> is received without a valid request, the ERROR word is transmitted.

Firmware Update
If your VGC50x firmware needs updating, e.g. for implementing a new
gauge type, please contact your nearest INFICON service center.
A firmware update is possible
User Parameters
•
via a USB memory stick (type A connector on the front of the unit), or
•
with the USB Update Tool via the USB type B connector on the rear of the unit.
Most of the settings you may have made in the Parameter mode will not be affected by a firmware update. However, we recommend that you save the parameters before an update (→  62).
Firmware update with a USB
memory stick (type A)
Not all USB memory sticks are automatically recognized by the
VGC50x, as they (particularly cheaper brands) do not always conform to
USB standard specifications. Try a different memory stick before contacting your nearest INFICON service center.
