OPTIONAL EQUIPMENTS
Modbus TCP/IP interface to H23 device.
• Integrated Ouman Access-connection
• Modbus TCP/IP
• Modbus TCP/IP RTU Gateway
• SNMP alarm transfer
OULINK ETH
GSMMOD5
Adapter for H23 for networking. If Oulink ETH adapter is taken in use in
H23, it’s not possible to use GSM-mode simultaneously.
By connecting the modem to the H23 regulator, you can communicate with the
regulator text messages and pass this information on alarms to your mobile via
SMS.
If Oulink ETH adapter is taken in use in H23, it’s not possible to use GSM-mode
simultaneously.
The modem has a fixed antenna that can be changed to an external antenna
with a 2,5m cord (optional equipment) if needed. The modem’s indicator light
shows what mode it is in.

LED indicator light Modem mode/instructions
LED is not lit: Modem is not on. Connect network device to modem.
LED is lit: Modem is on, but it is not ready for use. Make sure that H3 and GSM modem
SIM card have the same PIN code, if PIN inquiry is in use.
LED is blinking slowly: Modem is ready for use.
LED is blinking rapidly: Modem is either sending or receiving a message. If you do not receive an
SMS from H23, check the SMS you sent tosee if device ID and keyword were
spelt correctly. Device ID is case sensitive. H23 can identify the operator in
use from the modem’s SIM card. Identication does not occur until PIN code
has been entered. If H23 does not identify the operator even though PIN is
correct, enter message center number. You can nd message centre number,
PIN code and device ID in ”System settings” > ”SMS settings” in your H23
device.
