GND RX TX +12V RX RX + TX TX + AXCAXB232++ 232++ Device FIG. 4 RS-485 wiring To enable RS-485, set jumper J2 to the ON position (refer to Setting the Internal Jumpers on page 7). Using Hardware Handshaking When the controlled device requires hardware handshaking, connect the wiring as shown in FIG. 5 Hardware handshaking wiring Installing the AXC-232++ in a CardFrame: 1. Hold the card by the tab end and slide the card into the frame, into one of the slots. Gently push the card in until it is firmly seated in the card connector slot. You do not have to disconnect the power to the CardFrame when you install the card. When power is applied to the card, the LEDs blink to indicate the connection. 6 AXC-232++ RS-232/422/485 Interface Card Installation and Wiring Replacing the Lithium Batteries The AXC-232++'s lithium batteries have a life of approximately 5 years to protect its memory. When you install the AXC-232++, record the date the batteries should be replaced. There is a danger of explosion if you replace the batteries incorrectly. Replace batteries with the same or equivalent type recommended by the manufacturer. Dispose of the used batteries according to the manufacturer's instructions. Never recharge, disassemble, or heat batteries above 212°F (100°C). Never solder directly to the batteries or expose the contents of the batteries to water. Before you remove the lithium batteries, contact your dealer and verify that they have a current copy of your program; this avoids any inadvertent loss of data and prevent an unnecessary service outage. Syntax: 'CHARD-<time>' Variable: time = 100 microsecond increments 0 - 255. Example: SEND_COMMAND AXC232, 'CHARD-10' Sets 1mS delay between all transmitted characters. Syntax: 'CTSPSH' Example: SEND_COMMAND AXC232, 'CTSPSH' Enables PUSHes, RELEASEs, and status on channel 255 ([0, 255] within the AXC-232++) for CTS hardware handshake input. Syntax: 'CTSPSHF' Example: SEND_COMMAND AXC232, 'CTSPSHF' Disables the 'CTSPSH' command. Syntax: 'EOFF' Example: SEND_COMMAND AXC232, 'EOFF' Disables the 'EON' command. EON Forces the AXC-232++ to ignore the transmitted characters on its receiver. Syntax: 'EON' Example: SEND_COMMAND AXC232, 'EON' Forces the AXC-232++ to ignore the transmitted characters on its receiver. Syntax: 'HSOFF' Example: SEND_COMMAND AXC232, 'HSOFF' Enables placement of characters in the buffer. [. . . ] SEND_COMMAND AXC_232, 'BAUDLOW' SEND_COMMAND AXC_232, 'CB1ON' SEND_COMMAND AXC_232, 'CB1OFF' SEND_LEVEL 0, level, variable SEND_STRING 0, string SEND_STRING 1, string Enables placement of characters in the buffer specified by CREATE_BUFFER 1. Disables placement of characters in the buffer specified by CREATE_BUFFER 1. Sends variable as the value for level. . Sends string out the RS-232 port. AXC-232++ RS-232/422/485 Interface Card 13 Programming Xmodem Timing Commands The following table lists the AXC-232++ Xmodem timing commands. Xmodem timeouts exist to accommodate potential Ethernet delays and for consistency among and within products. Any Xmodem timing command will change timing and retries for Axcess code download as well as SOFTROM transfer. [. . . ]
