Fig.2d. The link of transmitter and communicator or modem to <SIGNAL+> <SIGNAL-> transmitter terminals in
case of the resistance in current loop is smaller than 250Ω.
If Ro in current loop is lower than 250Ω is necessary to connect 240Ω resistor to current loop by
remove jumper from <SIGNAL-> and <TEST-> terminals.
After communication jumper should cam back at its place.
