Advantech ADAM-5511 Manual page 103

The ADAM-5090 is a 4-port RS-232 communication module to be
implemented with the following Advantech ADAM-5000 series main
units:
ADAM-5510 (with library Version V1.10 or above)
ADAM-5511
The ADAM-5090 is equipped with four RS-232 ports, which makes it
especially suitable for bi-direction communication. It can simulta-
neously read data from other third-party devices such as Bar Code and
PLC as long as these devices are equipped with a RS-232 interface.
Furthermore, the ADAM-5090 can issue commands to control other
devices. It is fully integrated with the ADAM-5000, ADAM-5500 and
ADAM-4000 series, and transmits data to each other through the
RS-232 port. The whole integrated system is an intelligent stand-alone
system and can connect and issue commands to control devices such
as printers and PLCs in remote factory location.
The ADAM-5090 transmits and receives data by polling communica-
tion, and each port can receive up to 128 bytes in the FIFO. For
continuous data longer than 128 bytes, please refer to Table 4.17 for
Baud Rate setting to avoid data loss.
