Additionally, it makes possible to replace the module firmware. Connect the port to the
computer by means of the same cable that was used for programming the INTEGRA
control panels from the computer, and then run the EthmFlash program.
2 – PWR/LOG LED – steady light indicates presence of the supply voltage; blinking LED
indicates that the user has logged in to the server.
3 – BUS ACT LED – blinking LED indicates the process of communication between
the panel and the module.
4 – ADR pins for setting module address (see M
5 – RJ-45 socket – intended to connect Ethernet cable to the module. It is necessary to
use a cable identical to that used to connect a computer to the network. The socket has
two built-in LEDs. The green LED indicates connection to the network and transmission,
and the yellow one – transmission rate in the network (10Mb/100Mb).
Description of terminals:
+12V – supply voltage input;
COM – common (ground);
TMP – input of module tamper circuit (NC) – connects the housing tamper contact;
if not used, it should be shorted to ground;
A_RS485_B – RS-485 port terminals (not used);
DATA, CLK – communication bus – connects the module to the keypad bus of the control
panel.

2. Module addressing

The address set on the module ADR pins must be different from those of the other modules,
keypads, etc. connected to the control panel keypad bus. The address should be set as
shown in Table 1.
