General Information Product Overview The GAI-Tronics SP2 POE station is part of a modular industrial multicast VoIP (Voice over Internet Protocol) communication system. The standard SP2 POE configuration is an indoor, multi- party, handset/speaker amplifier station using POE (Power over Ethernet) with RTU control. They are constructed of cold rolled steel with a gray or safety orange powder-coat finish. A number of options are available to add to or modify station capabilities (see the Features and Options sections below). SP2 stations connect to an Ethernet network so the loss of a single station will not adversely affect the rest of the system. The stations require a 100 Mbps link to a switch or router using Category 5e or better cable. To ensure the quality of SP2 audio, it is recommended that SP2 network traffic be isolated from other devices and that network switches and routers be properly configured for IGMP (Internet Group Management Protocol) snooping and multicast filtering. Maximum cable runs between SP2 stations and network switches are limited to 100 meters to comply with Ethernet standards. Figure 1. SP2 Station Front Panel

Manuals\42004-788L2A.docx 08/19 Speaker and 600-ohm Audio Output Volume The speaker volume potentiometer, R36, adjusts the signal level to the speaker from the page line. When 600-ohm audio is also connected, R36 will adjust the volume for both. The volume for the 600-ohm audio must be configured via the CLI (Command Line Interface) when only the 600-ohm audio output is utilized. The default setting is 4 watts from an 8-ohm speaker and 2 watts from a 16-ohm speaker. WARNING —Maximum output power may exceed rated speaker wattage resulting in speaker damage. To adjust the speaker or speaker and 600-ohm output volume: 1. Turn the SPKR speaker volume potentiometer R36 fully counter-clockwise. An audible test-tone will be heard from the speaker. 2. Slowly turn R36 clockwise until the desired output volume is reached. The test-tone ceases three seconds after no adjustment has been made. This setting can also be configured via USB or Ethernet connection using the CLI. NOTE: This setting is overridden if it is configured for the station using the SP2 Console in a mutually provisioned system. See the SP2 Configuration Guide, Pub. 42004-784. Receiver Volume The Receiver Volume is adjusted using the RCVR potentiometer R37. To adjust the volume for the handset: 1. Remove the handset from the cradle. 2. Turn the RCVR potentiometer R37 fully counter clockwise. An audible test-tone will be heard in the handset. 3. Slowly turn R36 clockwise until the desired output volume is reached. The test-tone ceases three seconds after no adjustment has been made. This setting can also be configured via USB or Ethernet connection using the CLI. NOTE: This setting will be overridden if it is configured for the station using the SP2 Console in a mutually provisioned system. See the SP2 Configuration Guide, Pub. 42004-784. Group and Station Number Selector Switches One Group-Number and two Station-Number hex-selector switches are used to configure SP2 stations for Mutual Provisioning (see Figure 10). Each hex switch has a small arrow to indicate the current setting. 1. Adjust the position of the Group-Number selector switch to the desired group [0-F]. 2. Adjust the two Station-Number switches to assign the station number [00–FF]. No two stations can be assigned the same address. At least one SP2 station must be configured as a Master Station to utilize Mutual Provisioning in an SP2 system. Master stations must be assigned addresses [0.01], [0.02], or [0.03] using the selector switches. Master station(s) store the configuration of all SP2 stations on the network. As SP2 stations are powered on, they retrieve the mutual provisioning configuration from the master station. See Pub. 42004-784, SP2 Configuration Guide, for detailed information on configuring SP2 stations and SP2 system mutual provisioning.
