Page 15: Cable Connections
(supplied) detailed in Appendix C (page 87) between the device port on the serial user device or host device and the RJ45 connector. An NTI RJ45MF-RS232-CO serial crossover adapter has been provided for connection of one DCE type device. More adapters can be purchased separately. -
Page 16: Dual Power Option
Figure 5- Power connections for SERIMUX with Dual Power option DC Power Option The SERIMUX-S-x-48V has connections on the rear for a user-supplied 48VDC power supply. This is typically used when the SERIMUX is installed in a Telecom environment. The SERIMUX-S-x-48V will accept a DC power source between 36~72VDC (48VDC nominal), positive or negative polarity. -
Page 17: Connect Sensors
NTI SERIMUX SERIES SSH CONSOLE SWITCH Connect Sensors The SERIMUX-S-x has two RJ45 connectors for attachment of up to two sensors to monitor environmental conditions. Sensors can be connected to measure temperature (ENVIROMUX-STS), humidity (ENVIROMUX-SHS), temperature and humidity (ENVIROMUX-STHS), temperature and wide range humidity (ENVIROMUX-STHS-99). A sensor can also be connected to detect liquids (ENVIROMUX-LDSx-y). -
