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.

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
