Esser 784870 RS232 Serial Interface Module
Product Code: 784870
A serial communication module that is installed in the interface slot on the control panel and factory-set to RS232. It is used to establish direct connection with a computer, recording device, or building management software over short distances. It is powered by 3.3 V DC and draws approximately 20 mA of current. The small 27 x 53 x 15 millimeter card eliminates the need to replace the control panel when interface requirements arise later.
