Strip 0. 25 inch of wire insulation off all wires. Insert each wire into the appropriate opening on the connector according to the wiring diagrams and connector types described in this section. Do not tighten the screws excessively; doing so may strip the threads and damage the connector. If the device is using a separate power supply, do not connect the power wiring from the AXC-232 to that device.

AXC-232 RS-232/422/485 Card 5 Programming Send_Strings Use the Send_String commands to transmit characters in either ASCII, decimal, or hexadecimal format. If any of the 3 character combinations in the table below are found anywhere within a Send_String program instruction, they will be treated as a command and not the literal characters. Send_Strings "27, 17, <time>" Sends a break character for the specified length of time. [. . . ]
