3.2
When you receive your VP-2117 PAC, there is one RS-232 communication cable
(CA-0915) provided with the system. The cable is used to connect your PC to the
VP-2117 or to an I-7520R (RS-232/485 converter) that can be purchased from ICP
DAS.
The default value of VP-2117's communication parameters are 19200 baud rate, 8
data bits, no stop bits, and one parity bit ( 19200, 8, N, 1 ). The RS-232 pin
assignment is defined as follows:
For the ISaGRAF Workbench RS-232 communications to operate properly, only the
RxD, TxD, and the GND signals are used. If your PC is running a hardware device
or software program that uses the CTS and DSR signals, you will need to wire the
RTS-CTS and DTR-DSR signals together as shown below.
