power supply) or relays (by using relays, it is possible to control high
power devices).
Z1…Z8
– inputs. For example, alarm control panel outputs can be connected to the
inputs (with the control panel and ETHM-2 module suitably programmed,
this will enable monitoring the status of control panel which is not fitted
with telephone dialer).
TIP, RING
– terminals for connecting the control panel telephone dialer.
Note: Do not connect the telephone exchange or any devices simulating the analog
telephone line to the TIP and RING terminals.
Fig. 1. View of the module electronics board.
Explanations for the figure:
1 –
battery connecting leads
(connect the battery only when the module is to be supplied
with 16 V (±10%) alternating voltage).
2 –
LED
whose blinking indicates the module status:
– lights up for a short while – the device operation is normal
– blinking regularly at a slow rate – configuration data memory error
– blinking regularly at a fast rate – module firmware update running
3 –
CR2032 3 V
battery
for backup of the real time clock.
4 –
RJ-45
socket
for connecting the module to Ethernet network. 100Base-TX standard
compatible cable should be used. The socket has two built-in LEDs. The green one
indicates connection to the network and data transmission, and the yellow one
- negotiated transmission rate (ON: 100Mb; OFF: 10Mb).
5 –
RS-232
port
which enables the module to be connected to the computer serial COM
port. The dedicated cable for making this connection, designated DB9F/RJ, is
manufactured by SATEL. Using a computer with the ETHM-2 Soft program installed,
you can configure the device and read the events.
