Fig. 4.5 Connection of cables

When the serial bus has been connected between the PC and the transmitter,

the PC is switched on. When using a PC, a terminal emulation programme

(e.g. Procomm Plus, Datastorm or Windows terminal) is started.

The factory settings for data transfer are:

• 4800 baud

• even parity

• 7 data bits

• 1 stop bit

• full duplex

NOTE

When the serial bus settings are changed, the transmit-

ter has to be reset before the new settings become ef-

fective.

The processor does not allow the following combinations:

• no parity, 7 data bits, 1 stop bit: if this combination is given the

HMP260 programme will change the number of stop bits to 2

• even or odd parity, 8 data bits, 2 stop bits: if this combination is given

the programme changes the number of stop bits to 1

Refer to the manuals of the PC and the terminal emulation programme when

giving serial settings.
