Connection to the UNI-TELWAY network
General
Type of connection
Card TSX SCP 114, physical support RS 485, connects to the UNI-TELWAY network using cable TSX SCP CU 4030 via the connection device TSX SCA 50, or by cable TSX SCP CU 4530 (provided with SUB-D 15 pin connector) via device
TSX SCA 62. The card is inserted in the processor or in module TSX SCY 21601.
The TSX SCA 50 is passive and made up of a printed circuit board fitted with 3 sets of screw terminal blocks. It is used to connect a station by branching on the main section of a UNI-TELWAY bus.
It ensures continuing operation of electrical signals, shielding and end of line adaptation function.
The cable of the PCMCIA card has bare wires at its ends which the user must connect to the terminal located inside the device.

Connecting to the Modbus/Jbus bus
General
Type of connection
The TSX SCP 114 PCMCIA card is connected to the Modbus bus using the linking cable TSX SCP CM 4030. This cable is connected to the branching device TSX SCA
50.
The cable of the PCMCIA card has bare wires at its ends which the user must connect to the terminal located inside the device.

Note: The length of the cable used (3 m), makes it possible to link a device to a
TSX SCA 50 connection device located within a 3 meter radius of the card. This length ensures connection inside a standard cabinet

Connecting
Modbus to
TSX SCA 50 device
Note: Important: on a Modbus/Jbus bus you must: l l
Polarize the line, in general in only one spot (usually on the master device) with
470
Ω
resistance. Connect R pull-down
to EMI- (D(A)) and R pull-up
to EMI+ (D(B)).
Adapt the line on the two end devices with a resistance of 150
Ω
between EMI+ and EMI- (EMI+ is already connected internally by the card).
Important: to connect TSX SCP 114 card to a PLC Series 1000 (S1000), EMI+ must be connected to L-.

General
Type of connection
Connecting the TSX SCP 114 card in Character Mode does not require any specific accessories.
The product reference for the RS 485/RS 422 PCMCIA card linking cable is
TSX SCP CX 4030. It is 3 meters in length.
The TSX SCP 114 PCMCIA card is connected in point to point to an RS 422A standard device VAX station type.
