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.

[. . . ] Used in 485 mode, this command inserts a delay between transmit enable and the first character being transmitted in each packet. Syntax: TXCLR TXEND 'TXEND-<time>' Variable: time = 0 - 255 in 100 microsecond increments. Example: 'TXEND-20' Sets 2mS delay between transmit enable and the first character to be transmitted. Enables software handshaking. 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. [. . . ]
