FTP, and he enables the following internal sensors: Rest Capacity, Battery Voltage, and Current. So,
besides the Sensor drivers there are 2 drivers needed:
-
Internal Driver
-
Output Driver
So, the maximum number of Sensor-drivers is: 16
– 2 = 14
So, there are 14 Sensor-drivers left for use with the CT2x sensors.
The total number of parameters is: 14 * 2 + 3= 31
So, the number of parameters is no problem (31 < 64)
He can connect 14 CT2X sensors max.
4.40.5 Power Switch Limitations
The Power Switch is capable of powering sensors up to 200 mA. The output voltage is 12 Volts DC.
4.40.6 Modem Firmware Upgrade
The modem inside the data logger is equipped with the latest firmware-version available. There is no need
for upgrading the software, even in the near future we don’t expect this to be needed. But just in the unlikely
event of the need of a modem firmware, it is possible to do so. This can be done with the modem mounted
on the board (in circuit programming). The procedure of upgrading modem firmware is not covered in this
manual. For more information, consult your local YDOC dealer.
4.41 SD-card
The SD-card used with the data logger is an 8GB type micro SD-Card, but can be replaced by smaller or
bigger SD-cards up to 32GB
. It is formatted in FAT 32, and is compatible for use with a PC. Don’t use other
cards than this type, because the performance of the data logger may be harmed. (This is because of the
speed of the SD-card, and even the low power performance can be affected by using a slower card). The
contents of the card may be read on a PC by using a card adaptor, or can be downloaded from the card,
by using the menu-
option “Data-download”. We recommend not removing the SD-card from the logger.
4.41.1 Inserting an SD-card
At the factory, the SD-card is already installed, but when the cards need to be re-inserted, pay attention to
the orientation of it. It should be inserted with the (gold-plated) terminals up.
