Overview
Compatible ADAM-5000 Series Main Units
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 (with library Version V1.10 or above)
5.1 ADAM-5090 4-port RS-232 Communication Module
Bi-direction Communication
The ADAM-5090 is equipped with four RS-232 ports, which makes it
especially suitable for bi-direction communication. It can simultaneously 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 communication,
and each port can receive up to 128 bytes in the FIFO. For continuous data
longer than 128 bytes, please refer to Table 20 for Baud Rate setting to
avoid data loss.
