General Product Description

The GreenSpring Computers IP-Octal Distribution Panel operates with Octal format IndustryPacks IP-Octal Serial and IP-Octal 422. Each panel interfaces up to two IndustryPacks to industry standard D9 connectors. Each D9 connector can be configured to meet individual channel requirements. The D9 output emulates the IBM-PC/AT style output for RS-232. These signal names are provided in Figure 9 of this manual.

The IP-Octal Distribution Panel is rack mountable into most standard 19" cabinets and only requires 1U (43.6mm) of rack space. Some mounting hardware is provided for your convenience. D9 to DB25 adapter cables are available in groups of eight. These adapters are shown in figure 10 of this user manual.

Installation and Jumper Options

The Octal panel can be mounted in a standard 19" rack with the provided hardware (4, 10-24 x 1" machine screws). consult the rack manufacturer if the provided hardware is not sufficient for installation.

IndustryPacks can be connected via a 50 pin flat cable to J1 and J2 (located on the back of the side panel). J1 is the upper connector, and it connects with channels 1A-1H. Be careful to put pin 1 in the right location. (The IP-50 cable is keyed to prevent incorrect installation)

Each channel of the Octal panel can be configured to meet individual needs. Each channel has a corresponding 16 pin jumper block. Factory default settings are shown below.

The above jumper setting will allow connection to DCE equipment. The pin assignment on the D9 connector will be as follows:

To allow connection to DTE RS-232 equipment, the following jumper setting is required:

The above jumper setting will assign pins on the D9 connector as follows:

To allow connection to DTE RS-422 equipment, the following wire wrapping is required:

The above jumper setting will assign pins on the D9 connector as follows:

The Octal panel can also be jumpered to support the following signals standard to some RS-232 equipment:
DCD (Data Carrier Setect)
DTR (Data Terminal Ready)
DSR (Data Set Ready)
RI (Ring Indicator)

Figure 8 shows the Pinout for the jumper blocks when connected to the IP-Octal serial (RS-232). The pins have been configured to provide the maximum amount of options with the use of shunt. If shunts are not available or the configuration required cannot be achieved with shunts, standard wire-wrapping can be done.
