Controlling Sm42A, Sm82A, Sm84A, Sm164A Matrixes With Dcs2, Keyplus Or Swc16 Keyboards - Videotec DCFIT Manuel D'instructions

Controlling SM42A, SM82A, SM84A, SM164A Matrixes with DCS2, KEYPLUS or SWC16
keyboards
Please follow the steps given below for correct installation.
• Set the Matrix with the OSM Videotec protocol at 1200 or 9600 baud (see matrix manual) corresponding
to the baud rate setting on the keyboard (DCS2, KEYPLUS or SWC16, see the respective manuals).
• Set the keyboard (DCS2 or KEYPLUS) with the On Screen Menu type matrix and Current Loop
communications. Set the same baud rate as the setting for the Matrix.
• Set the dip switches on SW1 in the DCFIT appropriately. Configure Dip 1 on SW1 according to the
baud rate used for the matrix and the keyboard. Leave Dips 2 and 3 in the OFF position. Set Dip4
to the ON position.
• Set both JP1 and JP2 jumpers to position A (see configuration of JP1 and JP2 jumpers on page 6)
• Connect the SMXXA matrix with the DCFIT (RS485, max. 1200 metres)
• Connect the keyboard with the DCFIT (Current Loop, max. 1500 metres)
• Power the DCFIT (GND and 12V= terminals of J1) using a local power supply or the matrix
The connection between the SMXXA matrix and the DCFIT must be made through the RS485 line on
terminals A and B of J1. A RJ-jack box and a telephone cable (supplied with the keyboard) must be used for
the connection with the matrix, according to the following table:
DCFIT
J1 Terminals
A RS485
B RS485
12V=
GND
NB: The SMXXA matrix can be used to supply power to the DCFIT. The power supply cables must
not be more than 50 metres long if power is supplied by the matrix.
Connection of the DCS2 or KEYPLUS keyboards with the DCFIT must be carried out using the RX, GND
and TX (Current Loop line) terminals of the J2 terminal. A RJ-jack box and a telephone cable (supplied with
the keyboard) must be used for the keyboard connection, according to the following table:
DCFIT
J2 terminal
RX (Current Loop)
GND (Current Loop)
TX (Current Loop)
Connection of the SWC16 keyboard with the DCFIT must be carried out by using the RX and GND
(Current Loop line) terminals of the J2 terminal. Moreover, a RJ-jack box and a telephone cable (supplied
with the keyboard) must be used for the keyboard connection, according to the following table:
DCFIT
J2 terminals
RX (Current Loop)
GND (Current Loop)
