Arc Interface - Aim TSX-P Series Bedienungsanleitung

ARC Interface Connections
The 9-way D-type serial interface connector is located on the instrument rear panel. The pin
connections are as shown below:
Pin

7
8
9
Pins 2, 3 and 5 may be used as a conventional RS232 interface with XON/XOFF handshaking.
Pins 7, 8 and 9 are additionally used when the instrument is connected to the ARC interface.
Using a simple cable assembly, a `daisy chain' connection system between any number of
instruments, up to the maximum of 32 can be made, as shown below:
The daisy chain consists of the transmit data (TXD), receive date (RXD) and signal ground lines
only. There are no control/handshake lines. This makes XON/XOFF protocol essential and allows
the inter-connection between instruments to contain just 3 wires. The wiring of the adaptor cable
is shown below:
All instruments on the interface must be set to the same baud rate and all must be powered on,
otherwise instruments further down the daisy chain will not receive any data or commands.
