The AC31B is an addressable RS232 interface designed for use in asynchronous serial communications. It allows connection of various slave serial devices, such as terminals, printers, and barcode readers, to a multidrop network. The host side of the interface operates on RS485/422, while the slave side can be configured for either RS232 or RS485/422. This interface supports full duplex communication and offers selectable baud rates ranging from 300 to 38400 baud. It is powered by either 220 VAC or a DC supply ranging from 10 to 28 VDC, with a power dissipation of less than 4 watts at 25¬8C. The operating temperature range is from 0¬8 to 70¬8C, and it can function in environments with up to 95% non-condensing humidity. The AC31B features a 64,180 8-bit microprocessor with 32K bytes of EPROM and RAM, and includes indicators for transmit, receive, and power status. It also allows for jumper-selectable addressing (0 to 255) and includes options for terminating and biasing resistors. The product has received agency approvals from UL, CSA, CE, and UKCA. However, it is important to note that the AC31B is listed as obsolete and is no longer available for purchase.
