AC4486 Specifications
Interface Options
Modem Mode – Full modem handshaking is supported by the transceivers when enabled in EEPROM.
Modem Mode is incompatible with RS-485 DE mode. Because Command/Data performs an alternate
function when this mode is enabled, CC on-the-fly commands cannot be used and Configuration
Mode is entered by forcing 9600 baud through the 9600_BAUD pin. Therefore, modem mode, though
enabled in EEPROM, will be ignored when 9600 baud is forced. Both modem interfaces are shown
below.
RS-485 DE Control – When enabled in EEPROM, the transceiver will use the GO0 pin to control the DE
pin on external RS-485 circuitry. If enabled, when the transceiver has data to send to the host, it will
assert GO0 Low, send the data to the host, and take GO0 High.
