1 VOLTAGE TRANSLATOR BOARD FEATURES X LVC Bus Transceivers for voltage translation x I/O ports matching configuration of I/O Selectable jumper pins for the direction of voltage translation Onboard Voltage Regulator to supply the V side. Easy connection to the I/O port via a 0 way box header that suits a standard IDC connector. mm Standard width for D Rail Modules GENERAL DESCRIPTION The Voltage Translator Board is an accessory board that performs level conversion of a V interface (I/O or microcontroller) to a V or lower interface. This board can be connected to a single port on the existing I/O Range. The Elexol I/O Range consists of Ether I/O R, Ether I/O DIP R, USB I/O R and the USB I/O DIP R. The board consists of two LVC Bus Transceivers that are used for the level conversion. Each device is configured for a set level conversion of either V to V or V to V for a single bit port. The jumpers on the board are used to route the direction of the signal for the voltage translation. Each jumper needs to be configured in the correct direction for the board to operate. V to V and V to V. The connection between the I/O module and the Voltage Translator board is via a 0 cm IDC connection cable. This cable is provided with the board. The board has been designed to a mm standard width so that it can easily be mounted in D rail mounting modules. 0 Elexol Pty Ltd Revision.0

These jumpers are split into two lots of eight, with one lot of eight for the V side and the other eight for the V side. Each jumper sets the direction of the pin to an PUT () or PUT (). Voltage Translator Direction Configuration Jumper The jumper direction needs to be set correctly in order for the device to work.

4 EXTERNAL VOLTAGE FOR LEVEL CONVERSION (J) The device is setup so that external voltages can be supplied to the voltage translator so that different level conversions can be used. When the jumper is placed, the power to the voltage translators is provided by the v regulator located on the board which is fed from the V supply from the I/O. With the jumper removed external power will need to be supplied to the V pin on the 0 pin box header or directly to the jumper pin. The minimum external voltage that can be provided to the translators is.v DC. COMMUNICATIONS SETTG UP THE PORT ON THE I/O FOR THE VOLTAGE TRANSLATOR BOARD The Port on the I/O can either be set as input or output to use the Voltage Translator board. Care needs to be taken to match the port directions on the I/O so that they correspond to the direction jumpers on the Voltage Translator board. CODG EXAMPLES For code on how to set the I/O port states please refer to the individual datasheet for the device.
