[8]: TRANSCEIVER X2-1
Position 8 is for the I/O interface for a single
transceiver module or for the first transceiver of a
dual transceiver module in transceiver slot two.
The options for this position are identical to those
for position six. There must be, at a minimum, a
transceiver X1-1 in transceiver slot one before
selecting a transceiver in transceiver slot two.
[9]: TRANSCEIVER X2-2
Position 9 is for the I/O interface for the second
transceiver of a dual transceiver in transceiver slot
two.
The options for this position are identical to those
for position seven. It is necessary to have a trans-
ceiver selection in position eight before selecting
transceiver X2-2. See Table 2-3 for possible trans-
ceiver combinations.
[10]: MV2–T1, 3–T1, 4–E1, 5–T1/E1
Position 10 is for the Maintenance Module,
depending on your system needs.
[11]: OPTICAL CONNECTOR TYPE
Position 11 is for the type of connector used for
the fiber optic cables for the optical transceiver(s).
2.3.2 Channel Module Descriptions
The above section, “FOCUS Chassis Options
Summary,” defined the configuration of the base
chassis with the common, or system, equipment.
This section describes the individual channel
modules and the types of application they support.
Channel modules can be supplied mounted in the
base FOCUS chassis or can be supplied individu-
ally as your applications change. You specify and
order the channel modules by referring to the
three- or six-digit alphanumeric codes listed here.
Each choice consists of a channel module and an
external interface.
Figure 2–2. Example FOCUS Module/Interface.
The 232 module provides hardened, point-to-point
RS-232 data communications at a rate up to
19,200 bps with two stop bits and 9600 bps with
no restriction on data structure. The rear interface
module has two female DB-9 type connectors.
The 64F module is identified on the physical
module as 64K. The 64F module does not have a
plug-in rear interface module. Instead, it supports
a direct fiber connection to the FOCUS 64KFE
Fiber Optic Extension for use with the RFL 9300
Charge Comparison Relay. The direct fiber output
(without 64kFE) is designed for use with ABB
REL350 relays.
The 64G module supports a G.703 interface and is
for use with specific IEC standard relays. The rear
interface module is labeled 64G and has a 25-pin
female D-shell connector.
The 64R module is identified on the physical
module as 64K. The 64R module supports both
RS 422 and RS-530 electrical outputs. The rear
interface module is labeled 64V/R and has a 25-
pin female D-shell connector.
