Page 7: Power
Power The BASRT-B requires 24 VAC or 24 VDC (see Figure 6) while drawing no more than 3 W of power. The recommended conductor size is 16–18 AWG. COM is directly connected to zero volts and the chassis is DC isolated from zero volts. Input connections are reverse-polarity protected. - Page 8 For MS/TP devices that share a power source with the BASRT-B, see Figure 7 for proper 2-wire bus connections and Figure 8 for proper 3-wire bus connections.

Page 10: Limited Power Sources
Figure 10 — 3-wire MS/TP Bus with Separate Power Sources Limited Power Sources The router should be powered by a limited power source complying with the requirements of the National Electric Code (NEC) article 725 or other international codes meeting the same intent of limiting the amount of power of the source. -
Page 11: Operation
Operation MS/TP Port The MS/TP port uses an isolated EIA-485 transceiver that is connected to a 3-pin removable connector (Figure 1). The EIA- 485 transceiver’s + and – lines tie to + and – pins of the connector. The SC pin ties to the circuit ground of the EIA-485 transceiver. -

Class C subnet mask of 255.255.255.0 (/24). Figure 12 shows the setup for accessing the MS/TP network using BASRT-B, a computer for configuration, and a connection to the MS/TP network. To configure the router, attach it to a computer with an Ethernet connection and a standard web browser. - Page 14 On some systems, this option is: ―My Network Places‖.

Page 16: Device Parameter
The BACnet/IP network number is a 16-bit value (1–65534). Each network within the BACnet internetwork must have a unique number. This includes the BACnet/IP and MS/TP sides of the BASRT-B. Do not use addresses 0 or 65535 since these addresses are reserved. IP Address (Default Value = 192.168.92.68) -

1. equals the highest MAC address of any master, and 2. all masters use sequential MAC addresses starting with 1 Since many BACnet devices do not allow this parameter to be changed, leave the BASRT-B at the default value. Max Info Frames (Default Value = 40) This is the maximum number of messages that can be routed onto the MS/TP network by the router per token pass. - Page 18 those passed by the router from BACnet/IP. The default value usually provides good performance. MS/TP Baud Rate (Default Value = 38400) The baud rate of the MS/TP network can be 9600, 19200, 38400 or 76800 bps. All MS/TP devices on the same MS/TP network must use the same baud rate.
