4 Operation
MS/TP Port
The MS/TP port uses an isolated EIA-485 transceiver that is connected
to both a removable 3-pin connector (Figure 1) and an RJ-11 jack. Either
connector can be used for the MS/TP line. The EIA-485 transceiver’s +
and – lines tie to + and – pins of both connectors. The SC pin ties to the
circuit ground of the EIA-485 transceiver and is isolated from both the
USB and Ethernet ports. You MUST connect the SC pin to the MS/TP
segment signal common — or MS/TP communication will fail!
The router can access 254 MS/TP devices and supports 31 devices on the
local bus at rates of 9600, 19200, 38400, or 76800 bps.
Ethernet Port
This port offers a shielded RJ-45 connector. Through auto-negotiation
and Auto-MDIX, it automatically matches its duplex setting, flow
control, data rate and signal polarity to whatever is needed by the attached
equipment. Thus, the provided CAT5 cable is the only cable needed for the
Ethernet hook-up.
IP Address Reset Switch
When pressed for at least 1 second (at any
time the router is under power), this switch
will reset the default values of the IP
address (192.168.92.68), gateway address
(192.168.92.1) and netmask (24). It is
accessed by a paper clip (or similar
device) via a small hole in the case — then after reboot, the default values
apply.
LEDS
Power glows green if power supplied to the unit is proper
Ethernet glows solid for a valid link (green for 100 Mbps or yellow
for 10 Mbps) and flashes to show activity
MS/TP flashes green when receiving valid MS/TP traffic
