Installation 2-3PRISM 3021

ATA

ORMAL

NVERTED

Position S1-7 is used to select if data is normal or inverted

as shown in Table 2-F.

Units at both ends of the circuit must have this

option set the same.

ROGRAM

LASH

Position S1-8 is used to enable or disable programming the

Flash memory as shown in Table 2-G.

When switch S1-8 is in the Up position,

the unit goes into download mode. After

downloading the unit, move S1-8 to the Down

position. If this switch is left in the Up position

and power is lost, the unit powers back up in the

download mode.

Address Switch S2

Switch S2 sets the unit address. When using the 3021 with

an 8100A Site Controller, each element must have a unique

unit address. The 8100A Site Controller can address up to 50

units (with addresses from 1 to 50). If the unit is not con-

nected to a site controller, the NMS unit address should be

left at the factory default setting of 1

where Position 1 is Up

and all other positions are Down (see Figure 2-3).

Figure 2-3 Switch S2

Switch S2 has eight positions used to create an 8-bit binary

code for an address in the range of 1 to 50. Switch position

S2-1 is the least significant bit (LSB) and S2-8 is the most

significant bit (MSB). If a switch is down, its value is 0. If

up, its value is that of the upper location. The values are

additive. For example, to set a unit address to 5, position S2-

3 (binary value is 4) and position S2-1 (binary value is 1)

would be set Up for a unit address of 5 (4 + 1). All other

positions would be set Down. If all the switches are Down,

the address is 1.

Configuration Switch S3

Switch S3 (Figure 2-4) is used to set the configuration

parameters listed in the following paragraphs.

NMS P

ORT

ATE

Positions S3-1 and S3-2 select the NMS port rate as shown

in Table 2-H. This is a serial RS-232 DCE port configured

for eight bits, no parity, and one stop bit. If the 3021 is being

used with the 8100A, the NMS rate of all units must be set

the same.

SUPV P

ORT

ATE

Positions S3-3 and S3-4 select the SUPV port rate as shown

in Table 2-I. This port is used to access the embedded termi-

nal interface. This is a serial RS-232 DCE port configured

for eight bits, no parity, and one stop bit.
