Jumper tree
ComAp
DIRECT
RS232/RS485 – selection of serial communication type
ADR1/ADR2 – selection between two available local communication channels
MODEM
HW/SW control – selection between modems with full interface
ADR1/ADR2 – selection between two available modem communication channels; IG/IS-NT
controllers only
Setting RS232/RS485 jumper to RS232 position is obligatory
Modbus (not available at USB port of I-LB+, USB port always works in ComAp mode)
DIRECT
RS232/RS485 – selection of serial communication type
ADR1/ADR2 – selection between two available local communication channels
MODEM
ADR1/ADR2 – selection between two available modem communication channels; IG/IS-NT
controllers only,
Setting HW/SW control has no influence; a modem with HW control is always expected in this
mode
Programming
For programming is necessary to close BOOT jumper. RESET jumper is used to reset the device. Close
jumper to reset the device. For programming is used FlashProg PC tool. Check if jumper P3 is set according
to your communication interface (mostly RS232 – position 1-2).
