Contact Closure Input and Relay Connections Contact closure input connections The IPL T CR48 can be connected to any relay providing a closure to ground (closed = logic 1 and open = logic 0). The contact closure inputs are connected to 5 VDC via a 1k ohm pull-up resistor and must be wired with a ground. This allows the input to be tied to devices such as motion detectors and alarms. You can define what this input triggers via control software. 1. Connect one end of the input cable to a 3.
Initial start up When you power on the IPL T CR48 for the first time, there are two ways to set up the IP address: zz Use the ARP (Address Resolution Protocol) command method. zz Use the direct PC method. The default Web pages that are preloaded on the IPL T CR48 provide a way to reconfigure the unit once it has an active network connection with IP access. These Web pages are compatible with Internet Explorer® (version 6.0 or higher).
4. On the PC, access the command prompt (from the Windows desktop, click Start, then Run, and type Telnet in the Run dialog box) then execute the arp -s command. Enter the desired new IP address for the IPL T CR48 and the MAC address (located on the rear panel of the controller). For example: arp -s 10.13.170.15 00-05-A6-00-0A-90 Figure 10. Executing the ARP Command 5. Execute a ping command by typing ping followed by a space and the new IP address at the command prompt. For example: ping 10.13.170.
Configuring the IPL T CR48 using direct PC connection This type of connection is used initially to connect to and configure the IPL T CR48. The default settings of the unit (IP address, subnet mask, and [optional] administrator name and password) must be changed in order to use the unit on an intranet (LAN) or on the Internet (WAN). 1. Plug one end of a CAT 5 crossover Ethernet cable into the rear panel Ethernet connector on the IPL T CR48. See figure 7 for RJ-45 connector wiring. 2.
Communication and Control This section describes communication with the IPL T CR48 as well as A/V device control. Topics that are covered include: zz Ports Overview zz Communication with the Interface zz Programmer’s Guide for the Telnet and Web Browser zz Device Control zz Troubleshooting Ports Overview Contact Closure Input Ports The contact closure inputs on the IPL T CR48 are able to detect a closed circuit between any of the inputs and ground.
Relay Ports The relay ports can be used for remote switching of low level signals. The relays can be activated via software in three ways: 1. The Port Settings default Web page found under the Configuration tab (figure 16) 2. Telnet 3.
