2. SETTINGS 2.1 Switch Panel Settings Communication parameters are set with the switches in the switch panel. Unfasten two screws to access the switches. Note that it is not necessary to turn off the IB-681 to access the switches. 1 2 3 4 5 6 7 8 Data Rate ON 64K : Factory setting 56K Figure 3 Switch panel 2.1.1 Data rate Set the data rate according to land line/network. The default setting is 64k (64 Kbps). 56k is for USA ISDN circuit, for example.
SW2: Terminal interface Interface with HSD terminal. OFF: RS-449 (D-SUB 37 pin connector). ON: RS-232 (D-SUB 25 pin connector). SW3: Automatic data rate switching Determines whether to receive data at data rate other than what is set with the Data Rate switch in the switch panel. OFF: Prevents reception of data received at data rate other than which is set with the data rate switch. ON: Enables reception of data received at data rate other than which is set with the data rate switch.
2.2 OID/DID and IMN Settings OID/DID and IMN are set on the communication unit, usually at the time of installation. The telephone for HSD calling is alos set by the installing technician. For more information, contact a FURUNO dealer or agent. 2.3 Terminal Unit Settings “9: HSD” is added to the Terminal Setup menu on the terminal unit. Additionally, the HSD is provided with the lock switch function, which you may set it as shown below. Press [2], [Enter]. [Terminal setup] 1: Tel No.1 2: Tel No.
2.4 Registering, Deleting Subscriber Number 2.4.1 Registering subscriber number Register subscriber number as follows with the No.1 telephone. The subscriber number may contain 20 digits (*, # cannot be registered). The number can be confirmed by printing the status display. 1. Pick up the handset of the No.1 telephone and confirm dial tone. 2. Dial subscriber’s no.
3. OPERATION 3.1 Calling An HSD call may be made automatically or manually. 3.1.1 Automatic HSD call All automatic HSD calls are carried and terminated from the HSD terminal. Automatic HSD calls begin when the DTE raises the DTR line in the serial connector. The Inmarsat terminal dials the pre-programmed number. Upon answer by the called system the HSD port is enabled and data transfer can take place. Automatic HSD calls fall into two categories: direct call and address call.
3.1.2 Manual call Manual calls are made with a telephone (designated at installation) connected to the communication unit. The HSD terminal must support manual calls. To make a manual call, turn off DIP switch SW1, and then dial subscriber number as follows: *55* or *56* aaa 00 bb xxxxxxxxx# Subscriber’s Number Country Code Automatic Dialing Land Earth Station (LES) Prefix for HSD Call 55: 56 Kbps 56: 64 Kpbs Upon answer by the called system the HSD port is enabled and data transfer can take place.
3.2 Receiving Certain HSD terminals cannot receive the RI signal and therefore cannot receive. 3.2.1 Automatic call mode and receiving operation Receiving processing depends on the setting of DIP switch SW1 as follows: SW1 State Remarks OFF (direct call) The HSD terminal uses the DTR signal to reply. To do this the HSD terminal keeps the DTR signal OFF when it is not communicating.
3.2.2 Receiving and automatic data rate switching A call arrives at the data rate set on a subscriber’s equipment, and the setting of DIP Switch SW3 determines if the call will be received or not when the data rate is different from that set on the IB-681. SW3 State Remarks HSD call not accepted when its data rate is different from that set on the IB-681. Use this setting when the synchro clock to the HSD terminal cannot automatically be changed to match data rate.

3.4.4 Automatic call clear sequence An automatic call is cleared when the DTR signal is received from the HSD terminal. The HSD terminal turns off DTR, then the automatic call is cleared. The HSD terminal sends clear signal to CES, then HSD modem turns off DCD and CTS. Finally HSD modem turns off DSR.

5. INSTALLATION WARNING ELECTRICAL SHOCK HAZARD Do not open the equipment unless totally familiar with electrical circuits and service manual. Only qualified personnel should work inside the equipment. 5.1 Mounting 5.1.1 Mounting location The mounting location should satisfy the following requirements: • The mounting location should be clean, moderate in temperature and humidity and well ventilated. • Be sure to leave sufficient space around the unit for maintenance and checking.
5.2 Wiring 5.2.1 Wiring between HSD modem and router A serial straight cable with a 25 pin connector (RS-232 interface) or 37 pin connector (RS449 interface) connects between the IB-681 and HSD terminal (ex. Router) as shown below. The interface to use is selected with DIP switch SW2. For the RS-232 interface, the length of the cable must not exceed 15 meters. If a longer cable is required use the RS449 interface instead. Only one HSD Terminal (Router) can be connected.

APPENDIX Usage Tips Communication with other makes of Inmarsat-B terminals HSD communications time may increase depending on communications content when the HSD modem is used in a network. In this case, normal telephone and fax communications are disabled (except distress), thus frequency of communications and communications time must be carefully considered when drawing up communications plans. If communications overlap one another, it may be necessary to install an additional MES.
