To adjust the position of a jumper , do the following:. Remove power from the IP unit. Remove the six 6 screws from the case top. Locate the desired jumper on the PCB assembly and use needle nose pliers to adjust the jumper , if necessary. Carefully lift up the case top and place it into position on the chassis bottom.

Secure the case top into position using the six 6 screws. Connect power to the IP unit. The IP has a number of options when connecting to the radio. Different jumper settings are required for different revisions of the PCB installed in the IP unit, and are noted below.

Set the jumper position listed for the line according to the connection type shown below. To connect the radio receiver audio to the IP, different jumper settings are required for different revisions of the PCB installed in the IP unit, and are noted below. Set the jumper position for the line according to the connection type shown below. The audio source must be after the squelch circuit to prevent sending continuous noise to the remote console.

Usually the common of the relay contact switch is grounded and the normally open contact connects to the PTT input.

An alternative method to ground the common of the relay internal to the unit is to jumper R line 1 and R line 2 with a piece of wire soldered closed. Usually the common of each relay contact switch is grounded and the normally open contact connects to the MON input.

The IP provides two 2 relay closures for controlling the frequency of the radio, or switching a remote ancillary device. The F1 and F2 contacts can be connected through the DB25 connector. Usually the common of each relay contact switch is grounded and the normally open contact connects to the radio frequency control terminals. An alternative method to ground the common of the relay R1 internal to the unit is to jumper R line 1 and R line 2 , and for relay R2 jumper R line 1 and R line 2 with a piece of wire soldered closed.

These lines are open-collector transistor outputs. They can be programmed on a per line basis to generate any of combinations. Jumpers J8 line 1 and J30 line 2 are used to select the pull up voltage. NOTE: Some radios provide a pull-up voltage. When this occurs, place the jumper into the null position. Recorder output - The analog audio is generated at the connection.

Tone and Console operation require jumpers set to specific locations. The following section discusses the jumper settings. The RX termination J14 line 1 and J24 line 2 should be placed in jumper position A on 4-wire systems for a single unit at the end of a line.

If multiple units are connected in parallel, only one 1 unit should have the RX termination jumper in the A position. The RX termination jumper should be in the null position on the rest of the units. Two 2 jumpers on the transmit pair allow a degree of control over the output impedance. The jumper positions for each line, depending on how many consoles are placed in parallel, are shown below.

The TX condition is caused by an active low. Console Mode — Input - An Ethernet packet supervisor is sent on detection. While under supervisory control, TX traffic from the Ethernet to the console is muted.

Tone Mode — Input - An Ethernet packet supervisor is sent on detection. Once the IP unit is connected to the system, the level potentiometers can be set. Access to test and adjustment points on newer versions of the IP are provided through labeled openings on the case top and on the front panel of the unit. On older versions of the IP, access to some of the test and adjustment points is provided through labeled openings on the front panel; however, the case top needs to be opened to access the other test and adjustment points.

These provide a point to measure the actual signal being placed into the radio or balanced TX line. It is also possible to place jumper J9 line 1 or J26 line 2 into the A position to decrease the output of the TX line by a factor of The final adjustment should allow for undistorted audio to be transmitted for the full range of transmission levels at the desired deviation. This can be accomplished by turning on the TX alignment tone and adjusting the TX output to 0dB, as measured into a ohm load.

The reading should be 0dBm with the AGC turned off. This allows for local TX audio to be sent back on the Ethernet and played at other consoles so both sides of the radio traffic can be heard.

The alignment for TX monitor is similar to 4-wire RX alignment. Verify the RX alignment is completed first. To perform a standard alignment for a 4-wire system , do the following:. Transmit a 0dBm test tone on the TX audio pairs pins 13 and Adjust potentiometer R for line 1 or potentiometer R for line 2 until 0dBm is measured between the test point and GND. The IP is factory tuned to the frequencies shown below.

The detection frequencies cannot be changed as they are coded into the software. However, any actual function or output can be made to work with any existing programmed frequency. Please consult the factory for special requirements for frequency selections. This section describes the programming information for the IP It includes information on setting the IP Address, accessing the IP web setup windows, the setup window standards, and an explanation of the fields on each window used to program the IP Contact your network administrator to obtain the network IP Address and Mask.

IP Addresses consist of four numbers separated by periods. For example, For more information on IP Addresses and subnets, consult your network administrator. NOTE: For operation on different subnets, a gateway address must be configured.

Connect power to the IP To check the IP Address and subnet mask at any other time, press and hold the line button on the front panel of the IP, and then momentarily press the IC button. In the Name field, enter com. Click OK. From the Bits per second drop down menu, select From the Flow Control drop down menu, select None. In the main HyperTerminal window , enter an uppercase S. Enter technobabble for the factory setup password. NOTE: The serial number is fixed and should match the case label.

The following is a brief explanation of the factory setup options shown in Figure B - Allows access to the password if it is new or forgotten. D - Allows the Subnet Mask to be manually entered or changed. E - Allows the Gateway Address to be manually entered or changed. F - Provides the ability to reset back to defaults the Board Parameters.

Press Enter. When Should this target obtain IP settings from the network appears, type Y to obtain the IP settings from the network, otherwise, type N. Close the HyperTerminal program. Before connecting the IP to the web browser, an IP Address compatible with an existing network must be set.

To access the IP web setup windows , do the following:. Open the web browser on the PC. From the User Name drop down menu, type admin or the Username. In the Password field, enter the appropriate Username password. If this is the first time the IP has been started and a password has not been assigned to the unit, no entry is required. Across the top of each setup window are links used to access the various IP configuration pages. On the left side of the links header, the name assigned to the unit, the MAC address, and the version number of the firmware are displayed.

A brief description of each link is provided below. To access a setup window , do the following:. To permanently save changes, do the following:. Click Submit.

Click Save Parameters. Changes are now permanently saved to the IP console. The Welcome window provides a basic description of the IP operating modes and a field to enter a descriptive name for the unit.

This name is displays at the top of each IP web setup window. To change the name of the IP unit , do the following:. In the Console Name field, enter the desired name up to 12 characters.

The fields on this window are described on the following pages. The Serial Number field displays the serial number of your IP The serial number label is located on the back of the adapter box and should match the number in this field. Welcome to ManualMachine.
